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.

Tourist accused of hurling rock at endangered Hawaii monk seal’s head is arrested by federal agents

Tourist accused of hurling rock at endangered Hawaii monk seal’s head is arrested by federal agents


A tourist who drew widespread condemnation in Hawaii after a witness recorded him chucking a coconut-sized rock at “Lani,” a beloved, endangered Hawaiian monk seal off a Maui beach, was arrested Wednesday by federal agents.

Igor Mykhaylovych Lytvynchuk, 38, of Covington, Washington, is charged with harassing a protected animal, the U.S. attorney’s office in Honolulu said, adding that National Oceanic and Atmospheric Administration special agents arrested him near Seattle. He was scheduled to appear in U.S. District Court in Seattle on Thursday.

The court docket didn’t list an attorney, and a person who answered the phone at a number associated with Lytvynchuk declined to comment.

A state Department of Land and Natural Resources officer last week investigated a report of Hawaiian monk seal harassment in Lahaina, the community that was largely destroyed by a deadly wildfire in 2023. A witness showed the officer video of the seal swimming in shallow water while a man watched from shore.

“In the cellphone video, the man can be seen holding a large rock with one hand, aiming, and throwing it directly at the monk seal,” prosecutors said in a criminal complaint. The rock narrowly missed the seal’s head, but caused the “animal to abruptly alter its behavior,” the complaint said.

When a witness confronted the man, he said “he did not care and was ‘rich’ enough to pay any fines,” the complaint said.

Maui resident Kaylee Schnitzer, 18, told HawaiiNewsNow she witnessed the incident while taking photos nearby.

“What he was picking up was like a rock the size of a coconut,” Schnitzer said. “It wasn’t no small rock. It was the size of a coconut. And he threw it right, directly aiming towards the monk seal’s head.”

Maui Mayor Richard Bissen said the charges send a clear message that cruelty toward protected wildlife won’t be tolerated. Lani’s return after the wildfires brought a sense of healing and hope during a difficult time, he said.

“Lani is a reminder that humanity and the instinct to protect what is vulnerable are still values people can unite around,” Bissen said in an emailed statement.

The mayor said he called the U.S. attorney in Honolulu to advocate for prosecution.

Hawaiian monk seals are a critically endangered species. Only 1,600 remain in the wild.

“The unique and precious wildlife of the Hawaiian Islands are renowned symbols of Hawaii’s special place in the world and its incredible biodiversity,” U.S. Attorney Ken Sorenson said in a statement. “We are committed to protecting our vulnerable wild species, in particular, endangered Hawaiian monk seals.”

If convicted, Lytvynchuk, faces up to one year in prison for each charge. He also faces a fine of up to $50,000 under the Endangered Species Act and a fine of up to $20,000 under the Marine Mammal Protection Act.

In 2016, a man was seen on video appearing to beat a pregnant Hawaiian monk seal in shallow water.
