Major earthquake triggers tsunami warning in Alaska (VIDEOS)
A powerful magnitude 7.2 earthquake struck off the southern coast of Alaska on Wednesday afternoon, prompting tsunami warnings across the Southcentral and Southwest regions of the state. The US Geological Survey (USGS) reported that the quake occurred at 12:37pm Alaska time, with its epicenter located roughly 83 miles (134km) southeast of King Cove. The tremor, initiatially measured at 7.3, was felt widely across coastal communities along the Aleutian Chain, Alaska Peninsula, and Cook Inlet. In response, the National Oceanic and Atmospheric Administration (NOAA) and the National Weather Service (NWS) issued tsunami warnings for the Alaska Peninsula, ranging from the Kennedy Entrance to Unimak Pass and extending toward Anchorage. Sirens going off in Old Harbor AK. The Homer Police Department issued an alert advising residents to seek higher ground, while Anchorage emergency authorities stated that the city, which is home to nearly 2/5 of the state's residents, faces no immediate threat. Sirens were heard blaring in Old Harbor and other affected areas, with the warning also broadcast over the radio, according to videos captured by local residents. 🚨 LIVE TSUNAMI ALERT BROADCAST - ALASKA RADIO STATIONS CUT IN🚨This is what it sounds like when the Emergency Alert System (EAS) takes over the airwaves.🚨People in the red zone are being told to get out NOW. There were no reports of casualties or structural damage. Earthquakes between magnitude 7.0 and 7.9 are classified as 'major' and can cause serious damage. The NWS later downgraded the warning to an advisory, urging residents to remain alert, after evaluating the potential threat to other North American coastlines.

Major earthquake triggers tsunami warning in Alaska
A powerful magnitude 7.3 earthquake struck off the southern coast of Alaska on Wednesday afternoon, prompting tsunami warnings across Southcentral and Southwest regions of the state. The US Geological Survey (USGS) reported that the quake occurred at 12:37 p.m. Alaska time, with its epicenter located roughly 83 miles southeast of King Cove, near Sand Point on Popof Island along the Aleutian Chain. In response, the National Oceanic and Atmospheric Administration (NOAA) and the National Weather Service (NWS) issued tsunami warnings for the Alaska Peninsula, ranging from the Kennedy Entrance to Unimak Pass and extending toward Anchorage. The Homer Police Department issued an alert advising residents to seek higher ground, while Anchorage emergency authorities stated that the city itself faces no immediate threat. The tremor was felt widely across coastal communities along the Aleutian Chain, Alaska Peninsula, and Cook Inlet. Authorities have urged residents to remain alert and comply with advisories, as aftershocks are expected and tsunami waves could still impact coastal zones. There were no immediate reports of casualties or structural damage. Earthquakes between magnitude 7.0 and 7.9 are classified as 'major' and can cause serious damage, with only 10–15 such events occurring worldwide each year. DETAILS TO FOLLOW

Alaskan volcano rumbling despite being dormant for over 100 years, scientists say
An Alaskan volcano that has been inactive for more than 100 years is showing signs of rumbling, according to scientists. However, there's a chance that the activity could be signs of a pending avalanche, rather than a volcanic eruption, NASA said. MORE: Eruption at Hawaii's Kilauea volcano sends lava shooting 1,000 feet in air The Iliamna volcano, located near the Cook Inlet in southern Alaska, last erupted in 1867, but would still rumble every few years due to avalanches large enough to register on nearby seismic and infrasound instruments, according to NASA. The region has recently experienced a "flurry of shaking," according to the Alaska Volcano Observatory. On June 15, seismic activity ramped up at a "nearly continuous" rate for several hours, the observatory reported. The Operational Land Imager, a sensor aboard the Landsat 8 satellite, acquired an image of the volcano on June 10, prior to when the rumblings began. MORE: Scientists solve mystery of 'zombie' volcano displaying signs of eruption for decades The seismic activity was similar to those caused by the initial slipping between rock and ice that preceded large avalanches on the volcano in the past, according to the AVO. Iliamna often experiences massive avalanches due to the combination of glacial ice weakened rock and volcanic heat, scientists say. Its peak is covered in glaciers, snow and ice and it sits on a base of Jurassic-era granite, according to the NPS. Since its last eruption, the volcano was recorded ejecting smoke and light ash in 1876, 1933, 1941 and 1947, according to the NPS. MORE: Mile-deep underwater volcano could erupt off West Coast this year, scientists say More reports of smoke and light ash were recorded for the late winter of 1956 or early spring of 1957, but those reports were not confirmed, the NPS said. In 1958, four columns of vapor were shooting out of vents on the eastern side of the volcano, according to the NPS. But that was the last time smoke appeared to be ejected by the volcano. Although Iliamna is remote -- located in the Chigmit Mountains within Lake Clark National Park and Preserve -- it is monitored closely be volcanologists due to its potential hazards. There are several communities within a 200-mile radius of the volcano that could be impacted in the event of an eruption, including Pedro Bay, Port Alsworth and Anchorage, according to the NPS. MORE: Hidden magma cap discovered at Yellowstone National Park The AVO monitors 51 other active volcanos within the state, including the Redoubt Volcano, Iliamna's more eruptive neighbor, which is also located within the preserve. The U.S. Geological Survey currently has Iliamna at a "normal" volcano alert level.

Glenfarne announces over $115 billion strategic partner interest for Alaska LNG project
June 3 (Reuters) - Glenfarne said on Tuesday that its unit, Glenfarne Alaska LNG, has completed the first round of its strategic partner selection process with over 50 companies who have formally expressed interest for over $115 billion of contract value for the Alaska LNG project. The 807-mile 42-inch pipeline project is capable of transporting natural gas to meet both Alaska's domestic needs and supply the full 20 million tonnes per annum (mtpa) Alaska LNG export facility, the company said. Phase One is expected to deliver natural gas about 765 miles from the North Slope to the Anchorage region. Additionally, the Phase Two will add nearly 42 miles of pipeline under the Cook Inlet to the Alaska LNG export facility in Nikiski, which will be constructed simultaneously with the LNG export facility. Glenfarne expects a final investment decision on the domestic portion of the Alaska LNG pipeline by the end of the fourth quarter this year.
