On September 9 of last year, in the middle of the morning, seismometers began lighting up around East Asia. From South Korea to Russia to Japan, geophysical instruments recorded squiggles as seismic ...

Seismic waves traveling through Earth's interior often propagate at different speeds depending on their direction, a ...

Geophysicists find link between seismic waves called PKP precursors and anomalies in Earth's mantle that are associated with hotspots associated with volcanism on the surface. For the decades since ...

New research published in the journal Geophysical Research Letters uses the San Gabriel Valley Basin in California as a case study for a new method of monitoring groundwater storage. Monitoring the ...

New NASA InSight research reveals that Mars has a liquid core rich in sulfur and oxygen, leading to new clues about how terrestrial planets form, evolve and potentially sustain life. Scientists ...

Complex interior: illustration showing the two different layers of the Martian mantle between the core and crust. Also shown is how the layers affect seismic waves detected by InSight. (Courtesy: IPGP ...

It was the USA's deadliest tornado in decades and the costliest ever recorded: The catastrophic EF5 twister that tore through Joplin, Mo., in May 2011 killed 158 people and injured over 1,000 in a ...

Applied geophysics is the study of how the Earth works and what it's made of. Scientists called geophysicists use this knowledge to explore what's under the ground, check for dangers like earthquakes, ...

Starting in the spring of 2018, experts around the world puzzled over strange seismic waves that no one actually felt but that were recorded globally by seismometers. Volcanic activity on the seafloor ...

Geophysics has shown that precise measurements and a little modeling can perform wonders, like showing us the detailed structure of the Earth’s interior despite the fact that it is inaccessibly buried ...
