Using supercomputer modeling, scientists have unveiled a new explanation for the geology underlying recent seismic imaging of magma bodies below Yellowstone National Park.

High-resolution recordings of the powerful infrasound waves generated by an eruption at Ecuador’s Tungurahua volcano have given scientists a rare view inside the activity at the volcano’s mouth. The acoustic waves generated by the July 2013 eruption were one of the most powerful volcanic infrasound recordings ever captured. The low-frequency infrasound waves from the eruption are too low for human ears to hear but were as powerful as waves one meter (three feet) away from a jet engine.

Scientists have used some of the world’s most powerful supercomputers to model ground shaking for a magnitude (M) 7.0 earthquake on the Hayward Fault and show more realistic motions than ever before.

A global view of some well-known deformation features on Venus’s surface may indicate it’s capable of crustal motion, and that motion might even be happening today, scientists report.
Scientists have never directly observed magma beneath the Earth’s surface. But thanks to the discovery of easily accessible magma chambers, it may now be possible, report scientists at the 2017 American Geophysical Union Fall Meeting in New Orleans.

New research reveals that mysterious intraplate seismic zones underwent significant deformation hundreds of millions of years ago.

Researchers have successfully quantified Earth’s vibrational “hum” using seismic instruments on the bottom of the ocean. A new study determined at the ocean bottom the frequencies at which the Earth naturally vibrates, and confirmed the viability of using ocean instruments to study the phenomenon.

A research team took to the lab to recreate the magmatic melt that once formed the lunar surface and uncovered new insights on how the modern moonscape came to be. Their study found found that one of the great mysteries of the lunar body’s formation – how it could develop a crust composed largely of just one mineral – cannot be explained by the initial crust formation and must have been the result of some secondary event.

Rising sea levels could diminish the ability of Brazil’s coral reef systems to weaken incoming ocean waves, resulting in stronger waves hitting populated areas on the Brazilian coastline, according to new research.

Scientists at the University of Utah report that small seismic signals emanating from lakes can aid science. As a record of wave motion in a lake, they can reveal when a lake freezes over and when it thaws. And as a small, constant source of seismic energy in the surrounding earth, lake microseisms can shine a light on the geology surrounding a lake.
