Earthquake swarm detected around underwater volcano near Hawaii


HONOLULU, Hawaii – Seismologists believe a recent uptick in earthquake activity off the coast of Hawaii’s Big Island is likely associated with the movement of magma beneath an underwater volcano, but even if an eruption were imminent, it would not lead to major impacts for the archipelago.

The United States Geological Survey says it has detected dozens of earthquakes around Kamaʻehuakanaloa, with at least two measuring greater than a magnitude 4.0.

The underwater volcano is located about 30 miles southeast of the Big Island – far enough away that the earthquake swarm has rarely been felt.

The agency says previous swarms around the volcano have led to thousands of tremors but did not result in eruptions that affected the islands.

“Elevated seismicity continues at Kamaʻehuakanaloa, but it is not expected to impact other volcanoes or any infrastructure on the Island of Hawaiʻi. The source of the earthquakes is difficult to determine at this time, but it may be related to the movement of magma beneath Kamaʻehuakanaloa. Prior swarms related to probable eruptions at the volcano have consisted of thousands of earthquakes over days to weeks. Eruptive activity at this volcano would have no impact on residents of the Island of Hawaiʻi,” the Hawaiian Volcano Observatory stated.

The name “Kamaʻehuakanaloa” was changed in 2021 from “Lōʻihi” by the Hawaii Board on Geographic Names in an effort to preserve the indigenous Hawaiian language and traditions.

The name roughly translates into ‘the child of the deep ocean,’ reflecting the mountain’s status off the Hawaiian coast.

Kamaʻehuakanaloa is a shield volcano similar to the more notorious Kīlauea and Mauna Loa mountains on the Big Island. 

The underwater volcano rises about 10,200 feet above the ocean floor but even at its tallest peak, is still several thousand feet below the ocean surface, according to the USGS.

The volcano’s last known eruption occurred in 1996, with only around a handful of episodes during the last 150 years.

The Hawaiian Volcano Observatory said it is closely monitoring the situation but has not issued any increased alerts.

Kilauea is currently the most volcano on the islands with occasional steam rising from a lava flow field, but the observatory says the mountain is not actively erupting.

PHOTOS: 4 ways locals celebrated July 4 this year


HONOLULU (KHON2) — Various celebrations — beyond the usual fireworks and barbecues — marked the U.S.’s 250th anniversary on Independence Day.

From regatta to an annual Japanese tradition on Oʻahu, here’s four other events that took place on this July 4.

84th Regatta

To start off the morning, the 84th Walter J. Macfarlane Memorial Canoe Regatta was held at Waikiki Beach.

“Today there’s a swell. It’s not huge, but it’s not flat, so I mean it’s like a perfect requirement day, there’s excitement, there’s enough activity to keep it, first the variable, and keep everybody on their toes, and it makes for close races,” said Jim Foti with the Lanikai Canoe Club.

Canoe paddlers of all ages hit the water for a full day of racing.

“We have had some really fun races this morning,” said Siana Austin Hunt, president of the Oahu Hawaiian Canoe Racing Association. “Our kids did really well. We also had some great finishes with a lot of crews finishing on the same wave.”

The regatta is a tradition that is recognized as the longest-running outrigger canoe races in the world.

America250

Kapiolani Park served as the backdrop for America’s once-in-a-lifetime celebration commemorating 250 years. The free event brought families together for food, music, performances and special recognition for our military and veterans.

“There’s a lot of people that’s been going around the different booths and the different venues and enjoying themselves, listening to the music every hour on the hour, and at the same time they’re looking at some of the auditory, tasting the various different types of food, and just enjoying yourself and relaxing,” said Lynn Mariano, commissioner of Hawaii America250 Commission.

La Hoʻihoʻi Ea

While many celebrated Independence Day, others gathered at Iolani Palace to reflect on a different perspective of Hawaiʻi’s history into statehood.

The event highlighted La Hoʻihoʻi Ea, or Sovereignty Restoration Day, which commemorates the history of the Hawaiian Kingdom and encouraged a discussion about Hawaiian sovereignty and self-determination.

“We’re here to reclaim our place to retell our stories and to resound the message of Hawaiian sovereignty restoration,” said Imai Winchester, lead organizer for La Hoʻihoʻi Ea.

The free event included cultural performances, music, educational exhibits, speakers and family activities. It was the first of a month-long series of events that will lead up to a celebration on July 26 at Thomas Square.

Organizers said it’s an opportunity to learn, reflect and celebrate Hawaiian identity.

Mōʻiliʻili Summer Fest

An annual Japanese tradition fell on the 4th of July this year. The popular Mōʻiliʻili Summer Fest drew in thousands to the Old Varsity Theater parking lot on University Avenue.

Now in its 13th year, the event prides itself on having one of Honolulu’s largest bon dances — and no obon festival is complete without taiko drums and andagi.

One of the booths was prepared to sell thousands of the deep-fried treat, with proceeds supporting Hawaii’s young athletes.

The festival is held every first Saturday of July.

First Alert Forecast: Classic Hawaii trade wind weather


HONOLULU (HawaiiNewsNow) – Partly to Mostly Sunny skies with windward and mauka showers drifting leeward at times. Most of the rainfall will be light and in the overnight to early morning hours with an increasing trend on Tuesday and stronger trends on Thursday and Friday; which is good because we need to beneficial rainfall.

View the latest weather conditions here.

Trade winds will continue blowing from the east all week while a high-pressure system sits north of Hawaii, keeping conditions mostly stable. On Tuesday, a weak weather system moving in from the east will bring some extra showers across the islands, but nothing major. A more significant system arrives Thursday through Friday—it’s actually the leftover remains of a tropical cyclone—and will bring noticeably heavier rain, especially on the windward sides of the islands (the sides facing the trade winds) and on mountain slopes, with humidity increasing as well. The highest rainfall will happen Thursday through Friday, though overall rainfall amounts will stay limited due to large-scale stability in the atmosphere.

A Small Craft Advisory now in effect for all Hawaiian waters (a warning for smaller boats to be cautious). A new long-period swell from the south-southwest is already moving in and will boost south shore surf heights to near-High Surf Advisory levels through Monday before gradually fading. East-facing shores will remain rough and choppy throughout the week from the strong winds, while north-facing shores will stay relatively flat. These windy conditions and Small Craft Advisories will continue through the entire week.
