The earliest scientists first observed the waves that earthquakes produce before they could accurately describe the nature of earthquakes or their fundamental causes, as discussed in Lessons 1–5.

When a 7.9-magnitude earthquake struck central China's Sichuan province in 2008, seismic waves rippled through the region, toppling apartment houses in the city of Chengdu and swaying office buildings ...

The Anchorage International Airport control tower collapsed, killing the controller on duty. ANCHORAGE, Alaska — For the first time, a new computer model details the path of destruction wrought by the ...

Scientists have known that seismic waves slow down when passing through ultra-low velocity zones, or ULVZs, but only knew they existed around hotspots that create volcanic island chains. Now, a new ...

Stanford researchers have devised a technique that transforms the tiny tremors generated by the everyday hustle and bustle of city life into a tool for probing the subsurface of Earth A new technique ...

How can we determine how empty or full the soil reservoir is in areas that are difficult to access? Researchers have now demonstrated an elegant method to track groundwater dynamics in high mountains: ...

Large earthquakes in densely populated areas can be deadly and very damaging to the local economy. Recent earthquakes in El Salvador (magnitude 7.7 on January 13, 2001), India (magnitude 7.6 on ...

Mars has had its first CT scan, thanks to analyses of seismic waves picked up by NASA’s InSight lander. Diagnosis: The Red Planet’s core is at least partially liquid, as some previous studies had ...

Researcher have uncovered a new geophysical phenomenon where a hurricane or other strong storm can spark seismic events in the nearby ocean as strong as a 3.5 magnitude earthquake. A Florida State ...
