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.

Alaska Senate budget crafters reduce dividend size in effort to avoid draw from savings

Alaska Senate budget crafters reduce dividend size in effort to avoid draw from savings


JUNEAU — Senate budget crafters have adopted a spending plan that includes dividend payments of nearly $1,600 for eligible Alaskans.

The Senate Finance Committee this week reduced the dividend payments approved by the House earlier this year, which would have given every eligible Alaskan nearly $2,300 and would have required a significant draw from already-depleted state savings.

The final dividend figure is set to be at the center of end-of-session negotiations. But other than the differences in cash payments to Alaskans, the two chambers are largely in agreement on the funding items in the operating budget, which covers the cost of running state agencies and services for the fiscal year that begins in July.

The House and Senate appear poised to hold the line on agency spending and include $175 million in one-time, outside-the-formula funding for public education to help make up for years without inflation-proofing and Gov. Mike Dunleavy’s veto of a permanent increase to the school funding formula.

Differences between the House and Senate spending plans — including the size of the Permanent Fund dividend — will be worked out by a small group of lawmakers from both chambers in the final two weeks of the session, which must end by mid-May.

By reducing the size of the dividend, Senate Finance Committee members said they hoped to avoid a draw from the state’s main savings account, called the Constitutional Budget Reserve, which requires the approval of three-quarters of House and Senate members.

Legislative Budget Director Alexei Painter said Thursday that the Senate’s spending plan would lead to a deficit of almost $7 million in the coming fiscal year — far less than the projected deficit included in the House version of the spending plan. Senate Finance Co-Chair Sen. Bert Stedman, a Sitka Republican, said he expected that by the time the spending plan was approved by both the House and Senate, the deficit would be eliminated altogether, producing a budget that balances expected revenues and spending.

According to an agreement between the Senate and House made earlier this year, the full Senate has until May 2 to pass its version of the operating budget. Once the Senate approves the budget bill, it will be sent to the House for an up-or-down vote. Unless a majority of House members agree to changes made to the bill by the Senate, it will be sent to a conference committee to work out the differences.

The biggest task for the conference committee will be to find common ground on the size of the dividend. Senate members said Friday that the number would likely be closer to the $1,600 figure they had proposed, because the House plan would have created a nearly $270 million gap in state finances — with few options to cover the deficit.

Those options could include either cutting the size of the capital budget, which is used to cover the cost of infrastructure projects and facility maintenance, or drawing from savings.

The Constitutional Budget Reserve had around $2.5 billion at the beginning of the current fiscal year, below the minimum $3.5 billion that Painter said is recommended to buffer the volatility in the price of oil, which still accounts for a large portion of state revenues.

Stedman said the Legislature should look to build the account — rather than drawing from it — by “at least half of a billion” to prepare for fluctuating oil prices.

“Reading the tea leaves, I don’t think that there is a will in either body, really, to do a draw from the (Constitutional Budget Reserve) account to access the additional funds,” Sen. David Wilson, a Wasilla Republican who serves on the Senate Finance Committee, said Friday. “No matter how much I wish I could give my constituents a larger PFD, I just don’t think the will in both bodies is going to be there.”

Wilson said the sticking points in the final weeks of the legislative session will likely come not in the operating budget, but from key pieces of legislation where the Republican-controlled House majority and the bipartisan majority in the Senate have not found common ground.

“I think that’s going to be more contentious than the operating budget this year,” said Wilson, listing energy, education, criminal law reform and election policy as the areas of disagreement.

“So there are still four big items where the House and Senate have not come to a fully agreeable compromise yet. I think that’s going to be more of a struggle to get consensus, over the budget,” Wilson said.

That would be a departure from past years, when the House and Senate have diverged in their visions for the operating budget, leading to dramatic budget showdowns in the final days of the session. The state budget is seen as the most important piece of legislation passed every session — and the only one constitutionally required to be adopted each year.

The Senate’s dividend amount was calculated by appropriating one-quarter of Permanent Fund earnings toward the dividend — at around $1,350 per eligible Alaskan — leaving three-quarters of the annual draw from the Permanent Fund to pay for state government. The Senate’s dividend was boosted by just over $200 per recipient in energy relief payments, which were calculated using excess oil revenue from the current fiscal year.

The House’s larger dividend plan was cobbled together using Permanent Fund earnings, energy relief funds and surplus earnings that would otherwise be deposited in the Constitutional Budget Reserve.

The Senate again added a so-called “waterfall” provision to the budget this year — similar to the one approved last year — meaning that if oil revenue in the coming fiscal year is higher than currently expected, some of the additional funds could be redirected to next year’s dividend payouts in the form of energy relief checks.

Unlike the dividend, which is taxed by the federal government, energy rebates are tax-exempt.

While the budget plans are largely similar, small differences remain between the funding priorities of the House and Senate.

The House included $20 million for the University of Alaska Fairbanks to achieve R1 status, the top classification for U.S. research universities. That funding was left out of the Senate’s version of the budget.

The Senate included $12 million in education funding to account for what federal officials have said the state owes certain districts in coronavirus relief dollars. The Dunleavy administration has disputed the federal government’s assertions, and the funding was not included in the budget by the House.

The Senate eliminated funding altogether for the Alaska Gasline Development Corp., which has received millions of state dollars to explore the development of a natural gas pipeline, with limited results. The House had reduced funding for the corporation but not eliminated it entirely.

Every difference between the House and Senate versions of the budget could become a piece of the final session negotiations, as lawmakers look to return to their home districts — and in some cases to awaiting re-election campaigns — in which legislative accomplishments could prove vital.

“I think the real knowledge here is that there’s not a lot you can do with this budget,” said Sen. Scott Kawasaki, a Fairbanks Democrat, explaining lawmakers’ pivot to focus on legislation that does not come with a price tag. “There’s not that many levers that you can move up or down. There’s not that much money that you can just transfer into savings. And there’s not that much money that you can transfer to increase the Permanent Fund dividend at this point.”

Judge says high-flying pilot can't transport pot to Alaska villages by air; his loss of license will stand

Judge says high-flying pilot can't transport pot to Alaska villages by air; his loss of license will stand


In 2017, the Federal Aviation Administration revoked James M. Fejes Jr.’s pilot’s license, after he had been flying cannabis products to shops around Alaska with Flying High Investments, his company that was dissolved in 2020.

Fejes challenged the revocation in federal district court, saying the federal government does not regulate commerce within the state of Alaska. He was not crossing state lines with his bundles of weed, so interstate commerce laws didn’t apply. His arguments failed the Ninth Circuit.

“Although many states have legalized recreational marijuana, it continues to be a controlled substance federally,” Judge Ryan D. Nelson wrote in the ruling.

Fejes, who held a pilot certificate issued by the FAA, came under scrutiny after Alaska’s Alcohol and Marijuana Control Office (AMCO) reported him for violating regulations pertaining to the transportation of marijuana. Despite marijuana being legalized for most uses under Alaska state law, Fejes’s activities were deemed illegal under federal statutes.

The FAA invoked § 44710(b)(2), a provision that mandates the revocation of a pilot certificate when the individual knowingly engages in an activity related to controlled substances punishable by imprisonment for more than one year. Fejes’s use of aircraft for the distribution of marijuana fell squarely within this provision, leading to the revocation of his pilot certificate.

Fejes contested the revocation, arguing that the FAA lacked jurisdiction to regulate purely intrastate commerce such as marijuana delivery within Alaska. However, the panel rejected this argument, citing the constitutional authority of Congress to regulate interstate commerce, including the use of airspace.

Furthermore, Fejes attempted to invoke an exemption under FAA regulation 14 C.F.R. § 91.19, which allows for the transportation of controlled substances authorized by federal or state statutes. However, the FAA maintained that this exemption did not apply to Fejes’s case, as it relied on a different provision in law.

Finally, Fejes challenged the interpretation of § 44710(b)(2) by the FAA, arguing that his conduct did not align with enforcement priorities outlined in a memorandum on marijuana-related prosecutions. However, the panel dismissed this argument, emphasizing that a criminal conviction is not a prerequisite for the revocation of a pilot certificate under the statute.

The ruling fortifies the FAA’s authority to regulate aviation activities, even in the context of state laws that conflict with federal statutes.

While the U.S. Department of Justice has directed prosecutors to use discretion in spending resources to pursue marijuana crimes in states where pot is legal, the court opinion noted: That “does not alter marijuana’s status — it remains illegal under federal law.”

April sun is eroding Alaska’s snow


ANCHORAGE, Alaska (KTUU) – Warming temperatures are taking a spring bite out of Alaska’s accumulated winter snow.

The warmth is causing the ice on interior rivers to begin the melting process and the river that many folks watch is the Tanana River, which snakes through the town of Nenana.

Mixed showers will remain a possibility along the western coasts and Aleutian Chain as a result of low pressure circulating in the Bering Sea.

With that rotation over the Bering, and high pressure over the Arctic, winds are whipping across the northern coasts. A blizzard warning is in effect for the central and eastern Beaufort Sea Coast through 10 p.m. Friday. Winds will gust to 50 mph, causing low visibility in blowing snow.

Southcentral Alaska sees a chance of showers move in Friday, along with increased cloud cover.

The showers will most likely be along the western side of Cook Inlet, and southern and eastern portions of the Kenai Peninsula.

The hot spot for Alaska today was Haines at 63 degrees.

The cold spot goes to Point Thomson at 11 degrees.
