☆ A mega-earthquake could strike the Pacific Northwest any day — and we're not prepared

People along the coast now have 10 to 30 minutes to reach high ground before a giant wave engulfs the Pacific Northwest. The scene above is a worst-case scenario of a megaquake striking the Pacific Northwest. "It's ominously quiet," Harold Tobin, Washington's state seismologist and the director of the Pacific Northwest Seismic Network, told BI. The Pacific Northwest, by contrast, only found out about the danger posed by the Cascadia subduction zone in the 1980s. The Cascadia subduction zone pushed those mountains up about 10 million years ago, carving the mountain range that makes the Pacific Northwest so stunning.

CNN —It started with a melting glacier that set off a huge landslide, which triggered a 650-foot high mega-tsunami in Greenland last September. And no place was immune; the signal traveled from Greenland to Antarctica in about an hour, he added. Eastern Greenland had never experienced a landslide and tsunami like this before, Svennevig said. The threat goes beyond Greenland, Svennevig said; similar-shaped fjordsexist in other regions, including Alaska, parts of Canada and Norway. Recent rock avalanches in the Arctic as well as in Alpine regions, are “an alarming signal,” she told CNN.

☆ Nankei Trough advisory: Japan is bracing for a once-in-a-century earthquake. Does it need to?

A special committee warned that another “major earthquake” could hit in the coming week – the first time in its history the body had issued this type of nationwide advisory. Then there’s the looming threat of the Nankai Trough megathrust earthquake – the most powerful of its kind, with magnitudes that can exceed 9. Japan’s government has warned of the possible Nankai Trough quake for so many years that the possibility of it occurring has become common knowledge. The ‘big one’The Nankai Trough is a 700-kilometer long (435-mile) subduction zone, which refers to when tectonic plates slip beneath each other. “I tell (my students), the Nankai Trough earthquake will definitely come, whether it’s your generation or your children’s generation,” he said.

☆ Earth’s inner core has slowed so much it’s moving backward, scientists confirm. Here’s what it could mean
▼ + stars: | 2024-07-05 | by ( Mindy Weisberger | ) edition.cnn.com time to read: +10 min

Comparing the timing of seismic signals as they touched the core revealed changes in core rotation over time, confirming the 70-year rotation cycle. But the depth and inaccessibility of the inner core mean that uncertainties remain, she added. The mysterious region where the liquid outer core envelops the solid inner core is especially interesting, Vidale added. “We might have volcanoes on the inner core boundary, for example, where solid and fluid are meeting and moving,” he said. Because the spinning of the inner core affects movement in the outer core, inner core rotation is thought to help power Earth’s magnetic field, though more research is required to unravel its precise role.

In January of 2014, a meteor fell from space off the coast of Papua New Guinea. Last fall, Benjamin Fernando, a planetary seismologist at Johns Hopkins University, led a team that re-examined the nearby seismic signals and concluded that they were not evidence of the extraterrestrial, or anything close to it. Recently, he sat down with The New York Times to preview what his team had found. In 2014, a meteor entered the atmosphere and went “bang.” Sometimes, you hear these meteors on seismometers. Avi Loeb wrote a paper to say that he’d found the seismic signal from this meteor and that he’d used it to locate exactly where the meteor debris fell.

☆ Modern US earthquakes could be century-old aftershocks, study says
▼ + stars: | 2023-12-04 | by ( Allison Chinchar | ) edition.cnn.com time to read: +9 min

Earthquakes vs. aftershocksThe modern seismic activity the researchers studied is likely a mixture of aftershocks from the big quakes from the 1800s and background seismicity, Chen said. “Are small earthquakes in the New Madrid seismic zone aftershocks of 1811-1812 or not?” Hough said in an email. “The new study considers the question from a different angle, considering how tightly clustered earthquakes are, and concluding that some of the events are ongoing aftershocks,” Hough said. Aftershocks might still be continuing, but once the normal seismic rate for the area returns, she said, you can no longer identify them as aftershocks. “For this reason, we seismologists sometimes disagree about which earthquakes are foreshocks or aftershocks,” Ebel said, “and I think those disagreements are inherently unresolvable.”

Estonian Navy Handout/Handout via REUTERS/File Photo Acquire Licensing RightsCOPENHAGEN, Oct 13 (Reuters) - Nordic and Baltic seismologists said that they had detected blast-like waves on Sunday when a Baltic Sea gas pipeline ruptured but that the data was not strong enough to determine whether explosives were involved. Waves measured after explosions tend to leave different signals to those sent out by earthquakes, the seismologists said. But processing the data had separated the seismic waves from the background noise even though stormy weather in the Gulf of Finland, an arm of the Baltic Sea stretching eastwards into Russian waters, had complicated the analysis, seismologists said.

“I shake it off, I shake it off,” Taylor Swift sang. A Taylor Swift concert in downtown Seattle last weekend shook the ground so hard, it registered signals on a nearby seismometer roughly equivalent to a magnitude 2.3 earthquake, seismologists said. “It’s certainly the biggest concert we’ve had in a while,” said Mouse Reusch, a seismologist at the Pacific Northwest Seismic Network, which monitors earthquake activity in the Pacific Northwest. “We’re talking about 70,000 people and all the music and paraphernalia associated with the concert.”The so-called “Swift Quake” recorded a maximum ground acceleration of roughly 0.011 meters per second squared, said Jackie Caplan-Auerbach, a seismologist at Western Washington University. Seismologists use acceleration to measure ground vibrations, which are then converted to the more conventional Richter scale, the common measurement for earthquakes.

☆ Scientists unlock secrets of Earth's wickedly hot innermost realm
▼ + stars: | 2023-02-21 | by ( Will Dunham | ) www.reuters.com time to read: +4 min

The planet's internal structure comprises four layers: a rocky crust on the outside, then a rocky mantle, an outer core made of magma and a solid inner core. This metallic inner core, about 1,500 miles (2,440) wide, was discovered in the 1930s, also based on seismic waves traveling through Earth. Scientists in 2002 proposed that lurking within this inner core was an innermost section separate from the rest, akin to a Russian Matryoshka nesting doll. The researchers were able to differentiate the two regions because the seismic waves acted differently between them. "The latent heat released from solidifying the Earth's inner core drives the convection in the liquid outer core, generating Earth's geomagnetic field," Pham said.
