Tsunami advisory issued in parts of Alaska after 7.3-magnitude earthquake
The US Geological Survey described the earthquake as a magnitude 7.3. After the quake, the National Oceanic and Atmospheric Administration issued a tsunami warning, which it later downgraded to an advisory.
The US Tsunami Center said the advisory was in effect from about 40 miles (64.4km) south-west of Homer to Unimak Pass, a distance of about 700 miles (1,126.5km). The area is sparsely populated – among the larger communities in the area is Kodiak, which is home to 5,200 people.
Meanwhile, officials in the Pacific north-west were evaluating whether there was any threat to coastlines there.
The first waves were projected to hit the village of Sand Point, a community of about 580 people on Popof Island, in the Aleutian chain. The first waves were projected to land there, but the state's emergency management division said an hour after the quake that it had received no reports of damage.
'We have seen other earthquakes in the area that have not generated significant tsunami waves, but we're treating it seriously and going through our procedures, making sure communities are notified so they can activate their evacuation procedures,' spokesperson Jeremy Zidek said.
In Unalaska, a fishing community of about 4,100 people, officials also urged people to move at least 50ft above sea level, one mile (1.6km) inland. In King Cove, which has about 870 residents on the south side of the Alaska Peninsula, officials sent an alert calling on those in the coastal area to move to higher ground.
In a social media post, the Kodiak police department urged residents to utilize emergency shelters in the local elementary and high school 'if you need to evacuate from the inundation zone', the Anchorage Daily News reported.
In a social media post, Washington Emergency Management wrote that 'there is NO DANGER for Washington state from this earthquake in Alaska' after analyzing data from Deep-ocean Assessment and Reporting of Tsunamis (Dart) buoys. Oahu Emergency Management added in a similar post that their is no threat to Hawaii either.
Although Anchorage residents may have received an emergency alert, there is no threat to Alaska's largest city, Anchorage Emergency Management wrote on social media.

Trump approves disaster relief for New Mexico mountain town battered by back-to-back floods
President Donald Trump has approved a federal disaster declaration for New Mexico after flash floods tore through a mountain village that had not yet recovered from a deadly flood that killed three people and damaged hundreds of homes three weeks prior. The declaration allows Lincoln County residents to apply for several forms of Federal Emergency Management Agency aid, including home repair assistance, lodging reimbursement and medical coverage for injuries or illnesses caused by the disaster. Severe storms last Wednesday brought flooding and landslides to an already damaged Ruidoso. At least five people who were trapped by the rushing water had to be rescued last Thursday. The southern New Mexico community and its surrounding towns have been reeling this summer, with afternoon thunderstorms bringing more rain than the mountainsides can handle. Past wildfires have stripped the hills of trees and vegetation, leaving the Ruidoso area vulnerable to repeated flooding.

What you need to know about derechos, an uncommon and destructive weather event
Prolonged wind events that unleash heavy rainfall and travel far distances sometimes qualify as derechos. Derechos can happen almost anywhere in the United States but are most common in the central and eastern regions of the country. Winds typically gust over 60 mph (97 kmh) and can cause damage comparable to tornadoes or hurricanes. Here's what you need to know about this uncommon form of extreme weather. What is a derecho? A derecho is a long-lived line of storms that often produces extreme wind damage, said Gino Izzi, a meteorologist at the National Weather Service's office in Chicago. Derechos can last eight hours or longer and travel hundreds of miles (kilometers) across the country with winds typically gusting over 60 mph (97 kmh). 'There's been instances where derechos have moved from Iowa all the way to Washington, D.C.,' said Izzi. Because of the intense straight-line winds and vast distances a derecho can travel, the damage they cause is sometimes comparable to the destructive forces of tornadoes or hurricanes. Hurricanes are low-pressure systems that form over tropical or subtropical ocean waters and have organized thunderstorm activity, according to the National Oceanic and Atmospheric Administration. Unstable air that is hot and humid is supportive of derecho formation. Derechos can happen any time of year, but July and early August are the prime time for this type of extreme weather, said Izzi. Derechos are an uncommon weather event and usually a small number occur each year, but Izzi said several years could pass without a recorded derecho. There are different types of derechos. Serial derechos tend to form with large, powerful storms and typically occur in early spring, fall and early winter. Progressive derechos are usually smaller and tend to form in summer as they feed off of hot, humid conditions. Hybrid derechos have characteristics of both serial and progressive types. Conditions that are favorable for derechos can also lead to small, embedded tornadoes, which are violently rotating columns of air that extend down from a thunderstorm and reach the ground. Derechos tend to produce much more widespread damage than tornadoes because they can produce a swath of damage that exceeds 100 miles (160 kilometers) in width, whereas the damage from violent tornadoes is typically less than a mile (1.6 kilometers) wide. Safety tips include using a radio to listen to the forecast, monitoring devices for severe weather alerts from the NWS and having access to a sturdy shelter. 'It can go from nice, calm weather to 100 miles per hour winds blowing down trees in literally a matter of minutes,' said Izzi. Where do derechos form? Derechos can happen almost anywhere in the U.S. but are most common in the central and eastern regions of the United States. Progressive derechos tend to favor the northern and central Plains eastward into the Midwest, Great Lakes, and Ohio Valley area. That is because domes of heat can form across central parts of the U.S. and derechos tend to form on the northern and northeastern flanks of the dome where there are high levels of atmospheric instability. This also tends to be where the jet stream winds are stronger. Humidity from crops like corn, also known as corn sweat, also magnifies how unstable the hot, humid air is. A 2003 derecho traveled from Arkansas through several southern states, including Alabama, Georgia and South Carolina. Two people died and 11 were hurt. A 2009 storm dubbed a Super Derecho by meteorologists traveled from western Kansas to eastern Kentucky. It caused several deaths and injuries and more than $500 million in damages by the time it had traveled more than 1,000 miles (1,600 kilometers). A 2020 derecho that traveled from eastern Nebraska across Iowa and parts of Wisconsin and Illinois reached wind speeds of a major hurricane. The National Weather Service's Storm Prediction Center reported winds approaching 100 mph (160 kph) in places. In Cedar Rapids, Iowa, residents emerged from their homes to find an estimated 100,000 trees had been snapped or torn out of the ground. In December 2021, a derecho in the Great Plains and Upper Midwest spawned at least 45 tornadoes, caused widespread damage and killed at least five people. Derechos can cause flash flooding Derechos can be associated with a slow-moving or nearly stationary band of thunderstorms. This could potentially lead to heavy rainfall and flash floods that can cause significant damage. Flash floods associated with a derecho that occurred July 4-5, 1969, caused Killbuck Creek in Ohio to rise more than 20 feet (6 meters) above normal level and at least two dozen fatalities, according to NOAA. ___ The Associated Press' climate and environmental coverage receives financial support from multiple private foundations.
