Seismologists are closely monitoring Mount Rainier after a swarm of earthquakes struck the Pacific Northwest’s tallest volcano this week. The U.S. Geological Survey (USGS) reports that hundreds of small quakes have occurred since the swarm began, making it the largest such event at the mountain since 2009.Wes Thelen, a seismologist with the Cascades Volcano Observatory, told FOX 13 Seattle that the quakes began as a concentrated group of seismic events happening in quick succession..."We had an increase in activity in seismic activity up to about 26 events an hour, which is a pretty good event rate for a quiet volcano,"...

Martin Köhler, a PhD candidate with the University of Queensland's School of the Environment, said the odd discovery was made while he and other researchers were exploring the southern side of the island of Tongatapu."It was late in the day, and we were talking to some farmers when they directed us to this boulder," ...Köhler says that the massive boulder's location much further inland beyond the team's field work area means that it must have been transported there by some tremendous force...When the first erratics were identified in the 18th century, they were initially considered a major paradox. However, it...

When a 6.4-magnitude earthquake struck central Croatia in 2020, it caused extensive damage to the city of Sisak's town hall—and led to a fortuitous archaeological discovery, The Miami Herald reports. During renovation and repair work to the building, construction crews encountered long forgotten and well-preserved Roman ruins buried just beneath the modern structure’s basement. Archaeologists determined that they belonged to a small theater or odeon, measuring around 65 feet in diameter, which would have once held musical performances and political gatherings. Croatian authorities described the unexpected find as “extremely valuable” and one that helps provide a deeper glimpse into the...

On March 28th, 2025, a magnitude 7.9 earthquake struck Myanmar, causing a rupture in about 460 kilometers (290 miles) of the Sagaing fault line that runs through most of the country, causing shaking of at least intensity X on the Modified Mercalli scale. As heavy shaking was felt throughout much of Myanmar as well as other neighboring countries, the fault line moved side-to-side by as much 6 meters (20 feet) in some places, a movement which was captured by the camera in this video. This is the first (and currently only) known instance of a fault line motion being captured...

A Mag 4.1 earthquake just a few miles south of Knoxville TN at 9:00 EDT 10 May 2025 shook the geological region around between Knoxville and Atlanta GA this morning. No nationally reported reports of damage or injuries, but a low magnitude earthquake less than 5.0 seldom causes much damage. Hillside rock falls and tree falls in the already wet soil after several days of rain are likely the closer to the epicenter one goes. Unlike California's very broken earth and rocks, where small magnitude earthquakes are not felt very distance from the epicenter, the very large, very rigid Eastern...

The Cascadia fault, a 600-mile-long collision between two chunks of the earth's crust off the Pacific Northwest coast, has been quiet for a long time, and that is not a comforting fact. Major earthquakes occur somewhere in the world every year or two. Catastrophic tsunamis - giant waves generated by undersea earthquakes or landslides - strike less often, and some of the largest of tsunamis originate in places that do not, at first glance, appear particularly treacherous. The devastating tsunamis created Dec. 26 by a magnitude 9.0 earthquake that killed as many as 150,000 people on the shores of the...

Source: University Of Washington Date: 2003-10-31 Japanese Shipwreck Adds To Evidence Of Great Cascadia Earthquake In 1700 Evidence has mounted for nearly 20 years that a great earthquake ripped the seafloor off the Washington coast in 1700, long before there were any written records in the region. Now, a newly authenticated record of a fatal shipwreck in Japan has added an intriguing clue. Written records collected from villages along a 500-mile stretch of the main Japanese island of Honshu show the coast was hit by a series of waves, collectively called a tsunami, on Jan. 28, 1700. Because no Japanese...

Researchers plot course of ancient American tsunami Researchers have calculated the scale of a giant wave that devastated the north west coast of America 1,100 years ago. Japanese scientists used computer modelling to recreate the devastation from the ancient tsunami. The team from the Disaster Reduction and Human Renovation Institution in Kobe say the work will help planners minimise the impact of any future wave. The researchers took clues from silt deposits found in the Puget Sound, a Pacific inlet above earthquake fault lines in the Seattle area. Experts say the tsunami could have reached up to seven metres in...

Bangkok experienced an earthquake, slow and rocking, back and forth, long time. No damage.

An earthquake rattled Los Angeles hours after the 2025 Academy Awards ceremony wrapped up in Hollywood, according to multiple reports. The 3.9-magnitude tremor struck North Hollywood at around 10:13 p.m. on Sunday, according to the United States Geological Survey. Shaking was reported to be felt miles across LA, including in Pasadena, Long Beach, San Fernando Valley, Torrance, Redondo Beach and Glendale, NBC Los Angeles reported. There have been no immediate reports of injuries or damages, according to ABC 7. The Los Angeles Fire Department posted on X that they would not enter “earthquake Mode” following the quake.

Santorini has been hit by a powerful, shallow 5.3 magnitude earthquake, which is the strongest to strike the Greek island during recent seismic activity in the area. The tremors were felt in Athens on Monday evening and measured a focal depth of 17km (10.6 miles). ... The tourist hotspot has been rocked by seismic activity since January and more than 12,800 quakes have been detected by the University of Athens' Seismological Laboratory. ... Landslides have occurred in many parts of Santorini due to the frequency and intensity of the tremors and experts have not ruled out a major earthquake. Seismologists...

BREAKING: 8.0-magnitude earthquake hits the Caribbean Sea - PTWC

Rémy Bossu, Secretary-General of the European-Mediterranean Siesmological Centre, said “days, or perhaps, weeks” would be needed to evaluate the unusual tremors but said that the series of quakes typically occur in the build-up to a larger tremor. A state of emergency has been declared in the idyllic Greek island of Santorini amid a series of near-constant tremors in recent days, which have almost emptied the famous Greek tourist haven of visitors and residents. The largest tremor so far was recorded on Wednesday evening, when a quake with a magnitude of 5.2 coursed through the island. It was the first to...

A state of emergency has been declared on the Greek island of Santorini after days of consecutive earthquakes. It comes after a magnitude 5.2 tremor was recorded at 21:09 local time (19:09 GMT) on Wednesday between the Greek islands of Amorgos and Santorini, making it the strongest in recent days. It is estimated to have occurred at a depth of 5km (3.1 miles). The decree will be in effect until 3 March to "address the emergency needs and manage the consequences", officials said. More than 11,000 people have already left Santorini, with around 7,000 departing by ferry and 4,000 by...

A series of earthquakes near the Greek island of Santorini have led authorities to shut down schools, dispatch rescue teams with sniffer dogs and send instructions to residents including a request to drain their swimming pools. he strongest earthquake recorded was magnitude 4.6 at 3:55 p.m. Sunday, at a depth of 14 kilometers (9 miles), the Athens Geodynamic Institute said. A few tremors of over magnitude 4 and dozens of magnitude 3 have followed. There were no reports of damage or casualties. Earthquake experts and officials from the Ministry of Climate Crisis and Civil Protection and the fire service have...

For the past decade, a suite of devices have been monitoring Axial’s every action — rumbling, shaking, swelling, tilting — and delivering real-time data via a seafloor cable. It’s “the most well-instrumented submarine volcano on the planet,” says Mark Zumberge, a geophysicist at Scripps Institution of Oceanography in La Jolla, Calif., who was not involved in the work. But in November, a particular milestone caught Chadwick’s eye: Axial’s surface had ballooned to nearly the same height as it had before its last eruption in 2015 — fortuitously, just months after monitoring began. Ballooning is a sign that magma has accumulated...

A strong earthquake shook a high-altitude region of western China and areas of Nepal on Tuesday, damaging hundreds of houses, littering streets with rubble and killing at least 95 people in Tibet. Many others were trapped as dozens of aftershocks shook the remote region. Rescue workers climbed mounds of broken bricks, some using ladders in heavily damaged villages, as they searched for survivors. Videos posted by China’s Ministry of Emergency Management showed two people being carried out on stretchers by workers treading over the uneven debris from collapsed homes. At least 130 people have been injured in the earthquake-hit area...

A 4.1 magnitude earthquake shook the Los Angeles County area on New Year’s Day. The temblor struck off the coast about 12 miles south of Rancho Palos Verdes and south-southwest of San Pedro at 8:27 a.m., according to the U.S. Geological Survey. The quake had a preliminary magnitude of 4.3 but that was later reduced to 4.1 by the USGS. Shaking from the quake, which had a depth of just over 7 miles, was felt across the county.
