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.

East Africa Rift is undergoing a process that will see the Horn of Africa split from the rest of the continent.
The epicenter of Mexico’s lethal September 2017 earthquake was less than 65 miles outside the nation’s capital.
Not all earthquakes are made equal. A study on the Sept. 2017 quake that killed 300 in Mexico City found that both its location and cause were unusual.
Seismic shockwaves after a meteorite’s collision could affect systems all over the planet.
Research suggests a new threat to life on Earth from the meteorite's crash: Via seismic waves, the impact triggered massive undersea eruptions, as big as any ever seen in our planet's history.
Fires break out across San Francisco after the April 18, 1906 earthquake.
According to current forecasts, California has a 93 percent chance of an earthquake with magnitude 7 or greater occurring by 2045. Early warning systems, now in development, could limit casualties and damage.

The Nov. 12 earthquake wasn't centered on any known major faults in the Earth's crust. In its wake, scientists will collect data to add detail to what they know about seismic activity in the area.

Human-induced earthquakes have been reported from every continent except Antarctica. We asked a geologist to investigate whether North Korea's nuclear tests could trigger geological changes.

As global demand for energy and mineral supplies increases worldwide, the number of man‑made earthquakes is expected to rise. That increases the importance of understanding connection between the two.
The city of Juchitan, on Mexico’s southern Pacific coast, was hit particularly hard by the 8.2-magnitude earthquake that shook the region on Sept. 7, 2017.
The Tehuantepec gap in southeastern Mexico, where this month's massive earthquake originated, was long thought to be 'aseismic.' On September 7, scientists learned otherwise.
South Korea’s Meteorological Administration, on the case.
Within hours of North Korea's latest underground nuclear test, Japan and South Korea were both able to independently confirm it had happened. How?

Gravity waves recorded in the sun for the first time reveal some interesting facts.
Research into the 2016 Kaikoura quake revealed a domino effect that could change our understanding of seismic events worldwide.
Romans stand on the road after leaving buildings following an earthquake on January 18.
Recent research contradicts the belief that a period of calm usually follows a serious earthquake.
Small earthquakes can point to a region where larger, destructive and potentially deadly quakes may occur.
Potentially deadly and dangerous earthquakes can strike at any time. But can authorities get some early warning from monitoring the hundreds of small quakes that usually go unnoticed?
Truth is out there.
Sonification is a technique for converting data into sound. It could transform the study of distant worlds.
