On the morning of November 11, just before 9:30 UT, a mysterious rumble rolled around the world. The seismic waves began roughly 15 miles off the shores of Mayotte, a French island sandwiched between Africa and the northern tip of Madagascar. The waves buzzed across Africa, ringing sensors in Zambia, Kenya, and Ethiopia. They traversed vast oceans, humming across Chile, New Zealand, Canada, and even Hawaii nearly 11,000 miles away. These waves didn't just zip by; they rang for more than 20 minutes. And yet, it seems, no human felt them. Only one person noticed the odd signal on the...

Full Title: "The mystery of the 'rumble in the Indian Ocean': Strange seismic waves that shook the world on November 11 baffle researchers" Mysterious seismic waves in the Indian Ocean that were picked up by monitoring stations from Madagascar to Canada three weeks ago have baffled scientists. Researchers and earthquake enthusiasts who spotted the signals have narrowed down the origin to a region just off the coast of the island Mayotte. The slow waves detected on November 11 rumbled for more than 20 minutes, unbeknownst to most people. They are similar to those typically seen after large earthquakes, which are...

Scientists have found evidence that an earthquake 3,800 years ago in Northern Chile is the largest in human history, according to a new study. The quake had a magnitude of around 9.5, prompting tsunamis that struck countries as far away as New Zealand and boulders the size of cars to be carried inland by the waves, according to researchers at the University of Southampton. Since earthquakes occur when two tectonic plates rub together and rupture, a longer rupture indicates a bigger earthquake, they said. "It had been thought there could not be an event of that size in the north...

Anon-earthquake event triggered the USGS ShakeAlert system, which dozens of people across the county reported feeling, despite it not being an earthquake. The U.S. Geological Survey (USGS) issued a statement via Twitter: Hi everyone - #ShakeAlert detected a non-earthquake event which triggered our system. Fortunately, no public alerts were sent out. This is a bit of a first time for us because these events happen so rarely. Apologies for any confusion from our previous tweets. — USGS ShakeAlert (@USGS_ShakeAlert) April 15, 2022 The USGS said they are investigating the cause of the non-earthquake event, and also tweeted they're improving the...

NASA's InSight lander arrived in November 2018 and started listening for Mars' heartbeat, we learnt something really remarkable: Mars is rumbling. To date, InSight has detected hundreds of marsquakes – enough to give us a detailed map of the Martian interior. Tkalčić and his colleague, geophysicist Weijia Sun of the Chinese Academy of Sciences, wanted to look for quakes that might have gone unnoticed in the InSight data. They used two unconventional techniques, only recently applied to geophysics, to hunt seismic events in the InSight data. Based on nine templates of known marsquakes, the pair detected 47 new seismic events,...

GEOMAGNETIC STORM WATCH (G3-CLASS): Strong G3-class geomagnetic storms are possible during the early UT hours of March 31st when a Cannibal CME is expected to hit Earth's magnetic field. During such storms, naked-eye auroras can descend into the USA as far south as, e.g., Illinois and Oregon (geomagnetic latitude 50o). North Americans should be alert for auroras after local nightfall on March 30th. The hours before dawn on March 31st are probably best for Europeans. Aurora alerts: SMS Text. X-CLASS SOLAR FLARE: Earth-orbiting satellites have just detected an X1.3-class solar flare (March 30 @ 1737 UT). The source is active...

Fatima and Antonio Soares, who are in their 70s, decided to leave their home along with dozens of other residents on Saturday, a week since thousands of tremors started to rattle the volcanic, mid-Atlantic island. Seismologists fear the more than 12,700 tremors, which have had a magnitude of up to 3.3, could trigger a volcanic eruption or a powerful quake. Dozens of other Sao Jorge residents also left early on Saturday, with the latest government figures showing about 1,250 people left the island on March 23 and March 24 alone. The region's CIVISA seismo-volcanic surveillance centre raised the volcanic alert...

A strong earthquake has shaken the eastern coast of Taiwan in the early hours of Wednesday local time. The tremor, estimated at 6.9 or 7.0 magnitude, was registered at the depth of 10 kilometers under the Philippine Sea, some 63 kilometers south of the city of Hualien.

The United States Geological Survey is tracking a 7.3 magnitude earthquake that has hit off the coast of Japan, triggering a tsunami warning.

It's a big one.

Parts of the central U.S. are at risk of a devastating magnitude 7 earthquake within the next 50 years, experts are warning, with added urgency due to what they say is a sense of 'complacency' in those areas. Experts have been predicting a magnitude 7 earthquake in the areas surrounding the New Madrid fault line in Missouri for decades. It covers an area including Memphis, Tennessee, as well as St. Louis, Indianapolis and Little Rock, Arkansas. Despite 45 million people living within the danger zone, warnings have largely been ignored, said Robbie Myers, the emergency management expert from the region....

A 6.2-magnitude earthquake struck western Guatemala early Wednesday, the United States Geological Survey said, though no injuries had yet been reported. The epicenter of the quake, which had a depth of 84 kilometers (52 miles), was in the coastal district of Escuintla, just under 100 kilometers southwest of the capital, Guatemala City. Local authorities put the tremors at 6.8 in magnitude, saying it was followed by an aftershock of 4.8.

LOWER TOWNSHIP, New Jersey (WPVI) -- There's still no word on what caused the mysterious booms in South Jersey on Tuesday. When Fran Garretson's home in Erma started to shake, she thought someone was stomping on her porch. "Like really walking hard or heavy. It lasted for a few seconds, a good 15-20 seconds," said Garretson. From Rio Grande to Lower Township to Cape May Courthouse, people felt and heard something strange around 1:30 p.m. "About 18 (minutes) after 1 p.m. we were out here on the apron of the firehouse. We felt the ground shake and a loud rumble...

On the morning of January 24, 2022, two earthquakes of M5.4 and M5.6, respectively, hit the department of Nippes, Haiti. According to the General Directorate of Civil Protection (DGPC), two people died while 52 others were injured. The housing and education sectors have been the most affected. In the Sud and Nippes departments, all schools were forced to close their doors. Some 21 students were admitted to the Sainte Thérèse Hospital in Miragoâne, including 7 who were unconscious and 3 “in a state of shock”. Approximately 190 houses were destroyed and more than 590 were damaged. No further damage to...

The disaster had a reported depth of 10 kilometers, and a 5.6 magnitude. The departmental delegate reported that one person had died and at least three people were hurt. In August of 2021, Haiti experienced a 7.2 magnitude earthquake that killed more than 2,000 people. At least 5,700 people were injured in the Caribbean nation, with thousands more displaced from their destroyed or damaged homes. The earthquake struck the southwestern part of the hemisphere’s poorest nation, almost razing some towns and triggering landslides that hampered rescue efforts in a country already struggling with the coronavirus pandemic, a presidential assassination, and...

Just watching the end of a 3 Stooges video on YT at 1:08 a.m. when it hit . Biggest one we've had since the 2 giant quakes that caused death and destruction almost 6 years ago . Rocked all of Kyushu and parts of eastern Honshu . Sure it'll make the US TV news today . We're ok here in Kumamoto , just a little shaken up . Finishing my Suntory beer before trying to get some sleep . It's almost 2 a.m.

A magnitude 6.2 earthquake was recorded at 12.21 pm California time, December 20. This was later reduced to 5.5 and another aftershock was measured at 5.7 and also reduced to 5.5 A very strong 5.5 earthquake was just recorded in a depth of 5.6 miles depth 45 miles off the coast of Eureka, California, USA. USGS also reported a 6.2 magnitude quake recorded off Petrolia, California Another aftershock was recorded off the coast of Ferndale, California.

Why is Earth pulsating every 26 seconds, and why canÂ’t scientists explain it after 60 years? This is an enigma wrapped in a periodically predictable mystery motion. It could be a harmonic phenomenon, a regular seismic chirp caused by the sunÂ’s energy, or a beacon drawing scientists to its source to begin a treasure hunt. âž¡ The world is weird. We'll show you how it works. In the early 1960s, a geologist named Jack Oliver first documented the pulse, also known as a "microseism," according to Discover. Oliver, who worked at Columbia University's Lamont-Doherty Geological Observatory at the time, heard...

A rash of seismic activity across an arc of southern Japan in recent weeks – including the most powerful earthquake to strike Tokyo in a decade – has triggered renewed concern that a major natural disaster may be imminent, potentially the much-feared rupture of the Nankai Trough. Experts and government agencies have called for calm and insist there are no signs of an impending disaster to rival the March 2011 magnitude-9 quake, a tremor that unleashed a towering tsunami and caused devastation across much of northeast Japan. The Great East Japan Earthquake caused nearly 20,000 deaths and the meltdown of...
