Earthquake of 6.3 magnitude hits east coast of Russia's Kamchatka peninsula
'EQ of M: 6.3, On: 22/07/2025 07:29:38 IST, Lat: 52.50 N, Long: 160.53 E, Depth: 50 Km, Location: Off East Coast of Kamchatka', NCS wrote on X ANI US A strong earthquake of magnitude 6.3 was recorded off the East Coast of Kamchatka, the National Center for Seismology (NCS), reported on Tuesday. According to NCS, the earthquake occurred at 7:30 AM (Indian Standard Time), at a depth of 50 kilometres. "EQ of M: 6.3, On: 22/07/2025 07:29:38 IST, Lat: 52.50 N, Long: 160.53 E, Depth: 50 Km, Location: Off East Coast of Kamchatka", NCS wrote on X. As per the NCS, the location of the earthquake was 1550 km West of Andreanof Islands, Alaska The Kamchatka Peninsula is the meeting point of the Pacific and North American tectonic plates, making it a seismic hot zone. Shallow earthquakes are generally more dangerous than deep earthquakes. This is because the seismic waves from shallow earthquakes have a shorter distance to travel to the surface, resulting in stronger ground shaking and potentially more damage to structures and greater casualties. Previously, a tsunami warning was issued for parts of coastal Alaska after an earthquake in the Gulf of Alaska, according to the US Tsunami Warning System, The New York Times reported. A tsunami warning is the most urgent alert issued by the National Weather Service in the United States, and it means that people should move to higher ground or go inland. A tsunami advisory means people should get out of coastal waters and stay away from beaches and waterways. A tsunami watch means experts are evaluating the threat, so stay tuned for further information. The Alaska-Aleutian subduction system is one of the most seismically active globally, producing more greater than M8 earthquakes over the last century than any other. Many of these earthquakes, as well as coastal and submarine landslides, create tsunamis. The region contains over 130 volcanoes and volcanic fields, and contains well over three-quarters of US volcanoes that have erupted in the last two hundred years.

Alaska Earthquake: 6.2 magnitude tremor strikes days after major quake, no damage reported
Alaska's seismically active coast has seen two major earthquakes in less than a week, both confirmed by the National Center for Seismology (NCS). On 21 July, an earthquake measuring 6.2 on the Richter scale struck the Alaska Peninsula . The tremor occurred at 03:58 IST at a depth of 48 kilometres. The NCS shared the update on X, stating, "EQ of M: 6.2, On: 21/07/2025 03:58:02 IST, Lat: 54.99 N, Long: 159.98 W, Depth: 48 Km, Location: Alaska Peninsula."

The NCS recorded that earthquake at a depth of 36 kilometres, again shallow enough to be considered dangerous. The NCS posted the following details on X, "EQ of M: 7.3, On: 17/07/2025 02:07:42 IST, Lat: 54.91 N, Long: 160.56 W, Depth: 36 Km, Location: Alaska Peninsula." Live Events — NCS_Earthquake (@NCS_Earthquake) This quake triggered a tsunami warning along parts of coastal Alaska. According to The New York Times , the US Tsunami Warning System issued the alert soon after the tremor in the Gulf of Alaska. In the United States, a tsunami warning signals an immediate need to move to higher ground or inland. A tsunami advisory urges people to stay away from coastal waters. A tsunami watch, on the other hand, means experts are still assessing whether there's a threat. Shallow earthquakes pose a greater risk Both of these earthquakes were shallow. That matters because when seismic activity starts close to the surface, the waves don't have far to travel. This results in stronger ground shaking. The impact can be more severe. Buildings, roads, and other infrastructure face greater stress. Casualties are also more likely in heavily affected zones, especially if aftershocks continue. The recent quakes highlight this vulnerability. Though no damage has yet been reported, the shallow depths of both tremors point to a continued risk of aftershocks. Alaska's volatile geology These events are not isolated. The Alaska Peninsula sits on the Alaska-Aleutian subduction system, one of the most seismically active zones on the planet. Over the last hundred years, this region has produced more earthquakes above magnitude 8 than anywhere else in the world. The area is also prone to coastal and underwater landslides, which can trigger tsunamis. There are more than 130 volcanoes and volcanic fields in the area. In fact, over 75 percent of all US volcanic eruptions in the last 200 years have taken place here. With tectonic plates grinding under the surface and the ocean close by, the region remains under constant geological pressure. Scientists continue to monitor the situation closely.

Earthquake Today: Tremors of magnitude 6.2 strikes Alaska
An earthquake of magnitude 6.2 struck Alaska on Monday, a statement by the National Center for Seismology (NCS) said. As per the statement, the earthquake struck at a shallow depth of 48km, making it susceptible to aftershocks. In a post on X, the NCS said, "EQ of M: 6.2, On: 21/07/2025 03:58:02 IST, Lat: 54.99 N, Long: 159.98 W, Depth: 48 Km, Location: Alaska Peninsula." Earlier on July 17, an earthquake of magnitude 7.3 on the Richter Scale rattled Alaska, a statement by the National Center for Seismology (NCS) said. As per the NCS, the massive earthquake occurred at a shallow depth of 36km, making it susceptible to aftershocks. In a post on X, the NCS said, "EQ of M: 7.3, On: 17/07/2025 02:07:42 IST, Lat: 54.91 N, Long: 160.56 W, Depth: 36 Km, Location: Alaska Peninsula."

Earthquake of magnitude 7.3 rattles Alaska, tsunami warning issued
An earthquake of magnitude 7.3 on the Richter Scale rattled Alaska in the early hours of Thursday (local time), a statement by the National Center for Seismology (NCS) said. As per the NCS, the massive earthquake occurred at a shallow depth of 36km, making it susceptible to aftershocks. In a post on X, the NCS said, "EQ of M: 7.3, On: 17/07/2025 02:07:42 IST, Lat: 54.91 N, Long: 160.56 W, Depth: 36 Km, Location: Alaska Peninsula."

Alaska has more large earthquakes than the rest of the United States combined. More than three-quarters of the state's population lives in an area that can experience a magnitude 7 earthquake. The nation's coastlines are vulnerable to the interrelated hazards posed by earthquakes, landslides, and tsunamis. In the marine environment, these events often occur in concert, and distant triggers can cause severe local effects, making the issue global in scope. As the population continues to migrate toward the coastlines, the social impacts of these hazards are expected to grow.

Tsunami alert as huge 7.2 magnitude quake hits off Alaska coast
A tsunami warning has been issued for Alaska after a 7.2 magnitude tremor struck at a depth of 22 miles rocked the Pacific and sparked a massive alert for the US state. A tsunami warning has been issued after a massive 7.2 magnitude earthquake struck just off the coast of Alaska, sparking fears of dangerous waves crashing into coastal areas. The US Geological Survey (USGS) said it recorded the tremor 50 miles south of Sand Point at about 12:30pm local time on Wednesday. The area is just south of the Alaska Peninsula, reports the Mirror. The National Tsunami Warning Center confirmed that a tsunami warning is now in effect for parts of South Alaska and the Alaska Peninsula, covering the Pacific coasts from Kennedy Entrance (40 miles southwest of Homer) to Unimak Pass (80 miles northeast of Unalaska). Officials are urging residents in the warning zone to be on high alert, stay away from the shore, and follow all emergency instructions. 'Thrust faulting' behind major tremor Experts at the USGS said the earthquake was caused by "thrust faulting on or near the subduction zone interface between the Pacific and North America plates", the same kind of tectonic movement responsible for many of the region's most dangerous quakes. The USGS added: "The preliminary focal mechanism solution indicates rupture occurred on a fault dipping either shallowly to the northwest, or steeply to the southeast. " Fears of serious damage A tremor of this strength has the potential to cause "serious damage," according to experts. Michigan Technological University experts previously said tremors between 7.0 and 7.9 can cause serious damage to affected areas. The Alaska-Aleutian subduction zone is no stranger to strong quakes. The USGS said: "Since 1900, nine other earthquakes M7 and larger have occurred within 250 km of the July 16, 2023 event. "The largest of these was a M8.6 earthquake on April 01, 1946, which occurred about 150km to the west-southwest of the July 16, 2023 earthquake. Join the Daily Record WhatsApp community!

"The 1946 M8.6 generated a tsunami that devastated the lighthouse on Unimak Island and swept away its five occupants. Tsunami damage also occurred at Dutch Harbor and Ikatan Island in the Aleutian Islands, on the west coasts of North and South America, and in Hawaii." Authorities will continue to monitor the situation closely. No immediate reports of injuries or damage have been confirmed.
