Though earthquakes have terrorized people since ancient times, it's only been in the past 100 years that scientists have come to understand what causes them, and to develop technology to detect their origin and measure their magnitude. In addition, engineers and architects have worked to make bu...
Other possible environmental effects include underwater earthquakes, as scientists have found a great deal of seismic activity in the area. Back in 1817, a 7.4 earthquake at the northern end of the Triangle caused a tsunami that violently tossed ships as far north as the Delaware River south of...

Learn about earthquakes and how they form. Discover the connection between plate tectonics and earthquakes, the formation of faults, and how scientists measure earthquakes using seismographs. Finally, explore best practices for earthquake safety. Related to this QuestionWhat is used to find earthquak...
Researchers from UC Berkeley are working together with Telekom Innovation Laboratories on a smartphone-based earthquake early warning system. In February 2017, the team presented the app MyShake, which can pool Android smartphones to create a network of seismic sensors that can warn of earthquak...
In addition, we have another concrete use case that looks at assessing damage postcrisis—for example, with earthquakes, looking at high-quality satellite imagery, automating the analysis for those images, and understanding better the magnitude of damage and the locations to expedite aid g...
In Haiti, after a devastating earthquake killed more than 100,000 people in 2010, personal seismometers were distributed to the homes of volunteers, and a “citizen seismic network” set up to help capture the location and magnitude of earthquakes, and monitor for dangerous aftershocks. Frigon ...
“We hope this new approach can really give people a better chance of catching those events early on, so that people have more time to react,” Zhan says. In 2018, similar research was published that showed that seafloor cables had the potential to detect earthquakes and tsunamis — but tha...
“People don’t really understand or realize how damaging aftershocks can be,” said Ipsen. “They could go on for weeks. I was here for Northridge, and some of the aftershocks were actually worse than the initial quake.” Aftershocks differ from earthquakes only in that we expect them. ...
So here’s the design thing: even earthquakes with high magnitudes will have different intensities, depending on how far away a person is from the action. While Ridgecrest shook intensely, Las Vegas just saw some swinging light fixtures. The designers of the app figured that most people wouldn...
