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.
Many of Greater Mexico City's 22m residents aren't receiving the help they need.
The military can make a big difference right away but humanitarian deployments should generally be rare and brief.
Natural disasters are not only bad in the short term. Many families will see their health, well-being and ability to escape poverty affected for decades, and some will be affected for life.
The interests of future holiday-makers are far from important in times of crisis, but tourism is economically key to these countries.
Shattered by powerful back-to-back earthquakes, Mexico is facing daunting damages across six states. Now Chiapas and Oaxaca, the country's two poorest states, which were hit first, fear neglect.
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.
A 8.1 magnitude earthquake hit off the coast of Mexico on 8 September 2017. Fortunately, initial fears of a damaging tsunami hitting the coastline now appear unfounded.
Within hours of North Korea's latest underground nuclear test, Japan and South Korea were both able to independently confirm it had happened. How?
Sometimes 'stuff' isn't just stuff.
The world's largest mud volcano has consumed several villages, but we're no closer to the answer of how and why it began.
From crossing a road to fracking for oil, everything has inherent risks. At best, we can only aim to agree that, on balance, they are contained and justified.
An international team discovers extreme underground conditions at New Zealand's Alpine Fault, which is due to rupture in a major earthquake in the next few decades.
Two years after the second earthquake rocked Nepal in 2015, the recovery efforts have been stalled by political instability and money mismanagement.
Oklahoma is trying to limit the number of earthquakes caused by oil and gas extraction, but some existing faults there – which could be activated by wastewater injection – have never been mapped.
A new study suggests the enigmatic Makran region could see a magnitude 9 earthquake.
Research into the 2016 Kaikoura quake revealed a domino effect that could change our understanding of seismic events worldwide.
Can California's wet weather make earthquakes more likely? Scientists are still learning about what triggers these events. Even human activity can be a culprit.
