Scientists have discovered that a major earthquake zone in Southern California may be carrying more built-up stress than at any time in the past 1,000 years. While this does not mean a large earthquake is about to happen, researchers say the findings highlight the importance of being prepared. Earthquakes occur when stress builds up along […] The post California’s “earthquake gate” may be under m…

7.8-magnitude quake hit the southern island of Mindanao killing at least 55 people and leaving a trail of destruction It was just before midnight when the rescue team pulled the body from the rubble of a grocery store destroyed by the most powerful quake to hit the Philippines in half a century. The family wailed at the sight. “While tragic, it offered the family a painful consolation,” said Rene…

The largest Philippines shock in a half century -- a magnitude 7.8 event -- struck an earthquake-weary country on June 7, 2026, shaking the southernmost island of Mindanao. As of this writing, the Philippines authorities are reporting 47 deaths, several building collapses, and extensive building and infrastructure damage in General Santos City, which lays 55 kilometers (35 miles) north of the ep…

Scientists have confirmed a rare “impossible” earthquake deep beneath Utah, revealing a hidden source of seismic activity inside Earth’s mantle. Nearly five decades after a puzzling earthquake struck deep beneath northern Utah, scientists have confirmed that the event was real and part of a rare category of earthquakes that occur much deeper underground than researchers [...]

A huge earthquake fault line has been found underneath Auckland, New Zealand's largest city. The fault line, just south of the city, is active and could cause a city-destroying earthquake, new research shows. The discovery has also raised questions over a recent decision to exempt Auckland from earthquake building regulations. A study in the New Zealand Journal of Geology and Geophysics shows tha…

The city is exempted from earthquake building rules due to its northerly location, but a study of the Mangatangi Fault has thrown that into question A fault line south of New Zealand’s most populated city, Auckland, is active and could trigger a devastating earthquake new research shows, dispelling the region’s long-held belief it was largely immune from intense seismic activity. The research has…

California has enjoyed a relative lucky streak when it comes to earthquakes. How long will it last?

STEMgineer’s Guide to Problem Solving Workbooks Earthquakes shape landscapes, impact communities, and challenge engineers to design safer buildings. Some earthquakes are so minor that many […] The post How does an earthquake get measured? appeared first on STEM Education Works .

Earthquake was region’s strongest tremor in nearly 150 years and was also felt in parts of Mexico including Cancún An earthquake on Monday off the coast of Cuba , which was that region’s strongest tremor in nearly 150 years, could be felt in Florida and parts of Mexico . The 6.1-magnitude earthquake, which struck in the afternoon, occurred approximately 65 miles (105km) north-west of Mantua, Cuba…

The earthquake centered off Mindanao, the second most populous Philippine island, and injured nearly 500 people.

A magnitude 6.1 earthquake struck off the coast of Cuba in the Gulf of Mexico on Monday, with "reports of shaking across Southwestern Florida," according to a social media post from the National Weather Service’s (NWS’s) Miami office. The quake occurred 104 kilometers (about 65 miles) northwest of Mantua, Cuba, says Robert Garcia, a warning coordination meteorologist at the NWS Miami office. It o…

The magnitude-7.8 earthquake that hit the Philippines happened at a subduction zone, places capable of producing the largest earthquakes possible

People told to prepare for waves of up to three metres in parts of the Philippines, with smaller waves possible in Indonesia and Malaysia A magnitude 7.8 earthquake shook part of the southern Philippines early on Monday, sparking tsunami warnings on some regional coasts, collapsing some houses and killing at least one person. “Many buildings were affected, but I cannot enumerate them now because …

The Philippine Institute of Volcanology and Seismology said the epicenter was 8 miles from General Santos city on the island of Mindanao.

A magnitude 7.8 earthquake shook the Mindanao region in the southern Philippines, and a tsunami was possible on some coasts. But there was no threat to Hawaii or the U.S. mainland.

The Great Pyramid of Khufu has naturally survived millennia of seismic activity due to its immense mass, broad base, low center of gravity, and a structural frequency mismatch that prevents destructive seismic wave amplification

Scientists are now warning that scaling back the Ocean Observations Initiatve could put Washington and Oregon at risk. However, the cable system managed by the UW Pacific Northwest Seismic Network used for earthquake and tsunami monitoring is not being removed. ESS Professor and PNSN Director Harold Tobin is interviewed.
