Lori Dengler | A 60-year perspective on the Great 1964 Alaska earthquake


At 5:36 p.m. AST on Good Friday 60 years ago, a small crack formed about 16 miles beneath the ground near Prince William Sound on the south coast of Alaska. Over the next four minutes, the rupture would grow both towards the surface and laterally, displacing rock along a 500 mile long by 125-mile-wide fault surface, uplifting some areas by more than 30 feet and dropping others down nearly 8 feet.

For the whole time and area that the fault ruptured, it generated seismic waves. Almost everyone in Alaska felt it, from Ketchikan in the southeast to the eastern Aleutian Islands, and as far north as the Brooks Range, an area of over 800,000 square miles. If I center that same felt map near Humboldt Bay, It would have been felt from Los Angeles to Seattle and inland to Utah and Idaho.

Remembering what happened on March 27, 1964, is not only of historic interest. Very large earthquakes are rare and one of the few places on the planet where they occur is right beneath your feet, if you live in coastal Northern California, Oregon, or Washington. Examining what happened in Alaska provides clues to what could happen here.

I’ve read and heard many accounts of people who were in Alaska that day. There is one that is unique. Bob Pate was a salesman for radio station KHAR in Anchorage and aspired to be an on-air reporter. He carried a portable tape recorder with him and, whenever anything of interest happened around him, would turn it on and describe what was happening. That’s what he did from his home that evening.

“Hey, we’re going through an earth (voice trails), hey boy that’s an earthquake for sure…woo-ee, that’s a good one, boy oh boy oh boy,” the recording begins. From the breathlessness of the narrator, he is very frightened. You can hear everything in the house rattling and crashing. Pate stumbles over words as he tries to describe what is going on and frequently repeats himself. The recording starts about five seconds after the shaking began. By that time, the vibrations are already violent. This strong shaking phase lasts well over a minute and some swaying continues until the end of the recording, more than three minutes later.

While Pate is frightened, he is not panicking. The action of turning on the recorder is a rational one and his attempts to describe what is going on probably help to focus his thoughts. He describes moving the television off the table, so it won’t fall. After the strongest shaking passes, he does a tour of his house to check the damage. And just like I would probably do, he keeps flicking on the light switch only to be reminded that the power is out.

About 100,000 people lived in Anchorage in 1964 and all of them, like Bill Pate, were in the zone of strongest shaking. The Modified Mercalli (MMI) scale is a qualitative measure of shaking strength that varies from zero to XII. We often use Roman numerals to distinguish intensities from magnitude. Intensity V is the level when some items topple over and everyone indoors will feel it. The Anchorage area varied between VIII and X, strong enough to toss items into the air and damage even some well-built structures.

Despite the extreme level of shaking, only nine deaths were directly caused by the earthquake. Four were in Turnagain Heights, a middle-class suburb of newer homes built on the gentle hillslope above the Cook Inlet. When the shaking began, friction melted some of the frozen ground triggering liquefaction and causing 130 acres to slide a third of a mile towards the sea. The ground didn’t move uniformly. It broke into chunks forming great chasms in between. Some of the 75 homes atop the sliding ground likewise broke apart.

Liquefaction also played a role in other parts of Anchorage. The control tower at the airport collapsed killing an air traffic controller. Several areas in the downtown subsided damaging Penny’s Department Store where two people died and Government Hill Elementary School broke in half. Fortunately, it was a holiday, and no one was in the school at the time.

The Good Friday holiday and the early evening hour contributed to the low death toll. Schools and businesses were closed, and most people were at home. But the built environment also contributed; homes were built of wood, and outside of the liquefaction zones, had little structural damage despite their proximity to the fault rupture zone.

Fewer than one hundredth of a percent of the population died from shaking. But like Bill Pate, they were without power and other services. Areas of Anchorage were isolated from one another due to landslides and damage to roads and bridges. Severe weather prevented outside relief efforts for days; more remote areas were on their own for weeks.

For those first hours and days, it was neighbors helping neighbors. Alaskans are resilient by nature and set up informal neighborhood centers to help one another, sharing food and emergency first aid. One radio station was back on air within 24 hours, providing a calming voice and what little information was available. Lyndon Johnson, only four months into his presidency, declared a state of emergency, but it took days for assistance to reach Anchorage.

The details of what happened that Good Friday wouldn’t be known for years. It took painstaking field investigation and re-examination of data, some of which is still ongoing, to draw a more complete picture. 1964 was the dawn of the modern tectonic era and ‘subduction zone’ wouldn’t enter the literature for another six years. A very large earthquake had occurred nearly four years earlier along the coast of southern Chile and the magnitude scale in use at the time gave a value of 8.6. Using that outdated magnitude estimate, the 1964 Alaska had a value of 8.4, barely larger than the 1906 San Francisco quake then ranked at an 8.3.

It would take 15 years before the moment magnitude scale was developed and the true size of these great quakes could be accurately compared. The 1960 Chile earthquake still sits at the top of the earthquake leaderboard at a magnitude of 9.5, Alaska is in second at 9.2 and 1906 San Francisco earthquake, revised to magnitude 7.9, doesn’t even make the top 100. But these changes weren’t made until much later. For people in Alaska, they knew something extraordinary had happened.

We still use a variation of MMI today, although now it is augmented by instruments that measure ground accelerations and responses of people who experienced the earthquake on the USGS “Did You Feel It?” web site.

In case you hadn’t noticed, there is not one mention of a tsunami in what I have written above. Tune in to next week’s column for what happened then and how it might play out differently were a repeat to happen today.

In US Supreme Court case over which absentee ballots count, Alaska doesn’t pick a side

In US Supreme Court case over which absentee ballots count, Alaska doesn’t pick a side

Alaska’s appointed attorney general on Friday filed a friends of the court brief in a case before the U.S. Supreme Court involving whether absentee ballots that arrive after Election Day can be counted.

The filing does not side with either party in the case, which arose in Mississippi.

Instead, it informs the court of the logistical hurdles in Alaska — far-flung villages, lack of roads and severe weather — that make it difficult to receive absentee ballots by Election Day.

Alaska, like roughly half the other states in the U.S., allows some ballots cast by Election Day to be received later, the brief says.

The case, Watson v. Republican National Committee, challenges a law in Mississippi that allows absentee ballots received shortly after Election Day to count if they are postmarked by Election Day.

The Republican National Committee, the Mississippi Republican Party, the Libertarian Party of Mississippi and a Mississippi voter challenged the law in 2024. They argue that under federal law, ballots must received by state officials by Election Day to be counted.

The case could have national implications by influencing midterm elections, and comes amid baseless assertions from President Donald Trump that mail-in voting results in “MASSIVE VOTER FRAUD.”

The Alaska brief was filed by Jenna Lorence, the first Alaska solicitor general after Attorney General Stephen Cox created the role and appointed the Indiana attorney in October to fill it.

The 14-page brief says it does not support either party in the case.

The state’s impartiality drew criticism from an elections attorney, Scott Kendall, one of the main architects of the state’s ranked choice voting and open primary system.

“If you’re going to file something, take a position in favor of Alaska’s laws because they’re there for a very good reason,” Kendall said.

If the U.S. Supreme Court strikes down the law in Mississippi, that could lead to the disenfranchisement of many Alaska voters whose ballots arrive after Election Day, he said.

“Thousands upon thousands of Alaskans, through no fault of their own, wouldn’t be able to vote, and that’s not the democracy I signed up for,” Kendall said.

Under Alaska law, absentee ballots sent in state are counted if they are received “by the close of business on the 10th day after the election,” the filing says. Ballots from overseas must be received by the 15th day after the election.

Asked why the solicitor general did not take a position defending Alaska’s law or siding with either party, the Department of Law said in a statement emailed by spokesperson Sam Curtis:

“The State is committed to providing fair elections for Alaskans and will do so whatever rule the Court adopts. Alaska has previously filed these factual briefs to ensure courts understand the State’s unique perspective. Here, we wanted to ensure the Supreme Court knew how circumstances in Alaska make rules that might be simple in Mississippi more complicated in our State. We’re asking for clarity, so the Division of Elections and Alaska voters have straightforward rules to apply in the 2026 election.”

The filing notes that most Alaska communities are hard to reach.

“With over 80 percent of Alaskan communities off the road system, and extreme weather making access by boat or plane unreliable during certain months, including November, Alaska’s Division of Elections will continue to establish processes unlike any other State to ensure that its geography does not limit its citizens’ ability to vote,” the filing says. “Alaska asks that as this Court crafts a rule in this case, it provide clear parameters for Alaska to apply.”

The filing provides examples of how determining when a ballot was “received” by the Division of Elections is not always clearly defined, the Department of Law said.

In some cases, even in-person votes can struggle to reach the state elections division due to weather and geographical challenges, the filing says.

In 2024, poll workers in Atqasuk in northern Alaska tallied the votes cast on Election Day, but could not reach the elections division by phone that night.

So they “placed the ballots and tally sheets into a secure package and mailed them to the Division, who did not receive them until nine days later,” the filing says. “This exemplifies the hurdles that the Division regularly faces to receive and count votes from rural areas.”

The 5th Circuit Court of Appeals held that ballots must “be both cast by voters and received by state officials” by Election Day, the filing says.

“While that rule may invalidate laws like Mississippi’s delayed receipt deadline, what does it do in a situation like Atqasuk, where votes were cast and received by some poll workers on election day, but state officials did not receive the physical ballots or vote tallies until days later?” the filing says.

“Even more standardized voting situations in Alaska raise these questions,” the filing says.

“For example, when a voter casts an in-person absentee ballot in a remote area shortly before election day, the absentee voting official must send the ballot (in its unopened absentee ballot envelope) to the regional office, which may take some time,” the filing says. “Is the ballot ‘received’ the day it is turned over to the voting official? Or is it ‘received’ only once it reaches the regional office, where, for the first time, the Division evaluates eligibility before opening the envelope and counting the ballot within?”

“While it is clear when a ballot is ‘cast’ in Alaska (meaning that the vote cannot be changed), when certain ballots are actually ‘received’ is open to different interpretations, especially given the connectivity challenges for Alaska’s far-flung boroughs,” the filing says.

Alaska Lt. Gov. Nancy Dahlstrom, who oversees elections, said in a prepared statement that Alaska wants the Supreme Court “to provide clear guidance that protects election integrity while recognizing Alaska’s logistical challenges, so every eligible voter can make their voice heard.”

Cox said in the statement that Alaska wants the court to “consider how a rule that seems straightforward in some states might raise more questions in others. All we want is clarity in the rules.”

The filing also points out that for absentee ballots, many voters rely on the United States Postal Service.

“But unlike in other states, where mail delivery can be accomplished by simply driving to someone’s house via a continuous road system, USPS must use creative solutions to reach 82 percent of Alaskan communities,” the filing says.

In a separate matter, new guidelines from the U.S. Postal Service could also lead to votes not being counted across the U.S.

The postal service said on Dec. 24 it cannot guarantee that it will postmark ballots the same day they are put into a mailbox.

Multiple small avalanches release in Juneau after city issues evacuation advisory

Two small avalanches released on a slide path of Mount Juneau, above the Behrends neighborhood, as Ezra Strong was on a walk this morning in the pouring rain. 

The city issued an evacuation advisory about an hour earlier for Juneau residents in all known slide paths downtown and along Thane Road. Strong and his wife live on Gruening Avenue with their dog. He said he’s not heeding the advisory.

“I think in part because we’re a little bit protected by a rock wall and some other things behind us, in part because we have seen slides come down before on the main slide path that didn’t even get close to us,” he said.

During an online press conference Friday morning, the City & Borough of Juneau’s new Avalanche Advisor John Bressette said that many small slides reduce the hazard by decreasing the amount of snow that could be released in a larger slide.

“So it’s actually a good thing that we’re seeing smaller slides reducing the total snow load that is capable of producing an avalanche,” Bressette said. 

Some avalanches released above the Flume Trail today. The Alaska Department of Transportation and Public Facilities confirmed numerous small avalanches along Thane Road this morning. The agency expects more avalanches this evening since the forecast shows continued heavy rainfall, strong winds and warming temperatures. The closure of Thane Road could be extended multiple days.

Some residents of the Behrends neighborhood have evacuated to friends’ houses or Centennial Hall, the official shelter set up by the city and the American Red Cross.

Carlos Cadiente lives kitty-corner from Juneau-Douglas High School: Yadaa.at Kalé in the Behrends slide path. He evacuated at around 11:30 a.m. in one vehicle while his wife drove behind in another. At a stop sign, he told KTOO they were headed to a friend’s house just down the street. 

“We already had a go bag going and we already had the cars loaded up and ready to roll, and so we’re rolling,” Cadiente said.

He said this is the first time they’ve heeded an avalanche evacuation advisory in the decades they’ve lived here. 

“It’s kind of an extreme measure, you know, extreme weather that we’ve had,” he said. “So we’re just kind of trying to be proactive and not be a problem,” he said. 

Britt Tonnessen is the community disaster program manager for the Red Cross of Alaska in Southeast. In coordination with the city, the Red Cross set up an emergency shelter at Centennial Hall downtown for residents on Friday. 

At the shelter on Friday morning, she said the Red Cross has been preparing for the last week in case of an evacuation. 

“We’ve seen multiple fatal landslides and avalanches in the past decade,” she said. “Evacuating to a congregate shelter is not people’s dream idea. It’s a safe place to go. We do the best to meet the needs and we have incredible, loving, warm volunteers to meet people.”

Tonnessen said that anyone from avalanche zones, as well as those who feel the load on their roof is becoming too heavy, are welcome at the shelter. 

She said they are prepared to take 150 people, and around 30 people signed in by the early afternoon

Avalanche, weather and road conditions are expected to worsen this evening.

Only in Alaska. Welcome to the ‘totem pole capital of the world.’

Only in Alaska. Welcome to the ‘totem pole capital of the world.’


play

  • Ketchikan, Alaska is known as the “totem pole capital of the world” with over 80 poles.
  • Totem poles are unique to the Indigenous peoples of the Pacific Northwest and represent family history, stories, and events.
  • Many of Ketchikan’s oldest totem poles were moved from abandoned villages to the Totem Heritage Center for preservation.

KETCHIKAN, Alaska – An arched sign stretching between two city blocks welcomes travelers to “Alaska’s first city” and the “salmon capital of the world.” But Ketchikan, the first port on many Alaska cruises, has another nickname: the “totem pole capital of the world.” 

Totem poles are unique to the Indigenous peoples of the Pacific Northwest. The ones around Ketchikan are particularly old and numerous.

“The history and the clans that own (the totem poles), like their animal clan crests, those are still living,” said Irene Dundas, Cultural Resources manager for the Ketchikan Indian Community. According to KIC’s website, its tribal citizens descend from Southeast Alaska’s three main Native peoples – Tlingit, Haida, Tsimshian – as well as other Alaska Native tribal nations. “We’re not black-and-white photos … We still practice our culture every day, and we live it.”

“Travelers should know that there are spectacular and diverse Indigenous experiences and stories across every region of the United States, each unlike the other and each transcending generations to get to them,” said Sherry L. Rupert, who is Paiute and Washoe and CEO of the American Indigenous Tourism Association. 

Here’s what else visitors should know about Ketchikan, the “totem pole capital of the world.”  

Why it matters

“Totem poles are often used to show like family history, clan relationships, crest animals, stories, events, or to memorialize a specific person or event, like a battle or a visit by a dignitary, those types of things,” said Hazel Brewi, a visitor information assistant at the Southeast Alaska Discovery Center, an interagency visitors center for public lands across the state.

There are more than 80 totem poles around Ketchikan, many of which are visible to the public, according to Erika Jayne Christian, program coordinator for Ketchikan Museums, which include the Totem Heritage Center, where the oldest totem poles are found. 

Normally, she said, “They’re only really meant to last a generation – 70 or 80 years from the time that this giant western redcedar is felled and then carved and then raised in ceremony” until it naturally deteriorates. 

However, in the late 19th and early 20th centuries, residents of Native villages on neighboring islands began moving to Ketchikan for various reasons, including job opportunities. When surveyors went back decades later, they discovered many totem poles had been vandalized or stolen.

“When it comes to the totem poles, our village was totally wiped out by an expedition that came up,” said Teresa DeWitt, who is Tlingit and serves as a program assistant for Ketchikan Museums.  

To protect the totem poles that remained, elders from Tlingit villages on Tongass Island and Village Island and a Haida village on Prince of Wales Island allowed theirs to be moved. “It was a very big thing,” DeWitt said. “It’s not something we normally do.” 

The Totem Heritage Center was built to house these totem poles, which still belong to the villages’ descendants, and preserve and perpetuate the traditions behind them, with continuing guidance from a Native advisory board. 

Outside the center and elsewhere around Ketchikan, visitors can find newer totem poles, including recreations carved as part of a Civilian Conservation Corps project that began in 1930s and modern-day totem poles by master carvers. 

“There has been a real revival effort, and so people are learning to carve and learning to do Northwest Coast design,” said Dundas. “Totem poles are just a little sliver of the overall beautiful, beautiful culture.”

What to see

Visitors can see totem poles throughout Ketchikan, but there are three clusters. 

Totem Heritage Center: A $9 Museum Pass covers admission to both the Totem Heritage Center and its sister museum, Tongass Historical Museum. “You’re able to really learn about where it is that you’re visiting … where you are in place and time,” said Christian. 

Single museum admission costs $6 for adults under age 65, and $5 for those who are older. Admission is free for children age 17 and under, active-duty military service members, and local residents. Both museums are in downtown Ketchikan and reachable by foot from the cruise port or the borough’s free shuttle bus during the summer.

Saxman Totem Park: Visitors can see recreations of historic totem poles, a community clan house and a working totem pole workshop in the Organized Village of Saxman, less than 3 miles from downtown Ketchikan. Totem park tours run throughout the cruise season, from late April to early October. They can be booked directly through Cape Fox Tours, part of the village’s Alaska Native Corporation, or as excursions through cruise lines. Self-guided tours cost $8 while Cape Fox’s guided tours start at $129 and may include additional experiences, like traditional dance performances.

Kristy Shields, who is Tlingit, recalls being told as a kid “that we were going to dance on the dock for big canoes and it ended up being cruise ships.” Now she helps pass the tradition on to younger generations as tours dance manager for Cape Fox Tours. “They are dancing. They know their songs. They know who they are. They know where they come from.” Saxman can be reached by Ketchikan’s free shuttle in the summer or $2 city bus. There is also a foot and bike path, but walking from downtown takes about an hour.  

Totem Bight State Historical Park: More than a dozen Tlingit and Haida totem poles and a community clan house stand in this 11-acre state park, according to a guide on its website. Like many of the totem poles in Saxman, Christian said these were carved as part of a CCC totem pole restoration program. Park admission costs $5 per person from May through September and is free from October through April. The park is roughly 10 miles north of downtown Ketchikan and can be reached by $2 city bus. 

Not-so hidden gems 

Salmon Walk: This scenic 1.5-mile loop meanders through the heart of the city, along Ketchikan Creek, where salmon famously swim in the summer. There are various interpretative signs and points of interest along the way, including famous Creek Street and both Ketchikan museums. Visitors who don’t want to complete the loop can catch a free downtown shuttle from the Totem Heritage Center, which marks the path’s halfway point.

Southeast Alaska Discovery Center: This is a great point for learning about the region through ranger-led activities, educational films and elaborate exhibits. Three master-carved totem poles in the atrium represent the region’s three main Native peoples. Visitors can learn more through the Native traditions exhibit, developed by Tlingit, Haida and Tsimshian elders so “they could tell their own story,” Brewi said. “The voices of the elders echo through that space and it is absolutely beautiful to walk through, especially at the quieter times of the day, because it’s all motion-activated and you can actually stand and just listen to those elders speak.” 

The Southeast Alaska Discovery Center is located a few blocks from the cruise port. Admission is free from October through April. From May through September, admission costs $5 for visitors over the age of 15 and is free for anyone younger. Visitors with America the Beautiful Interagency Passes also get free entry. 

Tongass National Forest: Ketchikan is nestled within America’s largest national forest and the “world’s largest intact temperate rainforest,” according to the USDA. Visitors eager to explore the great outdoors will find over two dozen hiking trails around Ketchikan, many of which can be reached on public transit, according to Brewi. She recommends first stopping by the Southeast Alaska Discovery Center for the latest information on conditions and bears.

Best time to visit 

By far, summer is the busiest time of year with the mildest weather and the widest array of visitor experiences. Travelers hoping to avoid crowds may opt to visit early or late in the cruise season.  

However, Dundas notes, “Later in the season, like in October, you’re really, really pushing it with weather and you have to be prepared for Ketchikan weather.” Ketchikan got over 12 feet of rain in 2025, according to the National Weather Service, and October is among its soggiest months.  

She recommends visiting in July and early August, when various festivals are held, and packing a raincoat like locals.  

If you go

Getting there: Most visitors arrive by cruise, including more than 1.5 million people in 2025, according to the Ketchikan Visitors Bureau.  

Travelers can also fly into Ketchikan International Airport, a short ferry ride away on Gravina Island. Alaska Airlines provides daily service between Ketchikan and Seattle, as well as several other Alaska cities.  

Where to stay: Ketchikan offers a variety of hotels. Campgrounds and vacation rentals are also available nearby.
