California was thought to be an exception, a place where oil field operations and tectonic faults apparently coexisted without much problem. Not any more.
A network of sensitive instruments in schools around Australia is recording the eerie silence of the coronavirus pandemic — and tiny earthquakes that would otherwise be undetectable.

Puerto Rico’s January earthquakes came after many foreshocks and have been followed by numerous aftershocks. Scientists are studying these sequences to improve earthquake forecasting.
This unusual earthquake type generates an outsized tsunami.

A tricky kind of earthquake that happens in the soft rock of the ocean floor causes much larger tsunamis than their magnitude would predict. New research pinpoints a way to identify the danger fast.

There are three important issues to consider when thinking about quakes: what causes them; how to prepare and plan for them; and, how to move on after a damaging quake.

Engineers know how and where to build to minimize earthquake damage. But laws don’t always reflect that wisdom. A new study suggests it’s because of a mismatch between risk perceptions and reality.
The quake prompted several buildings to be evacuated in central Darwin.

Because it happened within the Australian Plate rather than at a plate boundary, shockwaves from the quake travelled more efficiently to Darwin than to cities closer to the epicentre.

North Korea is a major military threat to the US and its Asian allies, but exactly how powerful are its nuclear weapons? An earth scientist explains why it’s hard to answer this question.

New research shows that injecting wastewater deep underground can cause earthquakes far from the injection site. It also raises questions about which rock layers are the safest injection targets.
Africa’s physical landscape is not a permanent fixture and is being constantly shaped by massive geological forces.
