The USGS has issued its now annual seismic-hazard forecast for the central and eastern United States. The updated maps, which highlight both natural and human-induced earthquakes, show that millions of Americans are likely to feel the earth shake beneath their feet over the next 12 months.
A little-known fault underneath the southern Californian city of Santa Barbara is capable of producing stronger shaking and more damage during an earthquake than previously thought, according to new research. Called the Ventura-Pitas Point Fault, it’s now thought to be capable of producing magnitude 8.0 earthquakes,…
A magnitude 7.8 earthquake has rocked the Solomon Islands about 42 miles off the coast of Kirakira. A subsequent Tsunami watch was issued for Hawaii, but was canceled. Areas close to the quake are also on tsunami alerts.
A magnitude 6.5 earthquake struck Indonesia’s Aceh province earlier today, leaving 97 dead and hundreds injured. Though the quake did not trigger a tsunami, it triggered memories of the horrific 2004 Indian Ocean earthquake when more than 100,000 were killed in Aceh alone.
It’s generally believed that hydraulic fracturing is behind the recent spate of earthquakes in regions not usually associated with seismic activity, but the underlying processes are still poorly understood. New research from Canada strengthens the link between the two, showing how the controversial practice can…
Seismologists are warning that the latest earthquake to strike New Zealand could trigger other large earthquakes in the coming days and weeks, but sensationalistic claims of a devastating “mega-quake” are likely overblown.
A magnitude 5.0 earthquake rattled the Oklahoma prairie town of Cushing last night, damaging several buildings and threatening one of the world’s largest oil terminals. Earthquakes are now a disturbingly frequent phenomenon in the region, with all signs pointing to the practice of disposing oil and gas field…
A new ground displacement map shows the dramatic degree to which the Italian landscape moved during the October 30 earthquake, including an unfortunate mountain village that heaved over two feet.
Human-induced earthquakes are on the rise in the United States and Canada, likely as a result of oil and gas industry practices. New research suggests this isn’t a new phenomenon, and that several quakes felt in Los Angeles during the early 20th century were likely caused by human activity.
Geologists have discovered that two deadly faults beneath San Francisco—the Hayward and Rodgers Creek faults—may be linked. Should one slip, it could trigger the other fault to collapse as well, causing an earthquake even larger than the one that struck back in 1989.
A series of quakes under the Salton Sea may be a signal that the San Andreas Fault is on the verge of buckling. For the next few days, the risk of a major earthquake along the fault is as high as 1 in 100. Which, holy crap.
Oklahoma was hit with an earthquake yesterday, its second 5.0+ quake this year. The increased number of earthquakes have been linked to the use of hydraulic fracturing, or fracking—specifically the underground disposal wells where the run off from fracking is stored. The Oklahoma Corporation Commission has taken note…
A 5.6 magnitude earthquake shook parts of the US Midwest earlier this morning, rattling homes from Nebraska to North Texas. The unusually strong quake will likely draw further scrutiny to the practice of disposing oil and gas field wastewater deep underground.
Since the time of Isaac Newton, scientists have wondered if the gravitational pull of the sun and moon might be strong enough to trigger earthquakes and tremors on Earth. An analysis of 81,000 low-frequency earthquakes along the San Andreas Fault now confirms these suspicions.
Japan and Ecuador were rocked by major earthquakes over the weekend, prompting speculation that the two seismic events were somehow related. Here’s why that’s extremely unlikely.
A geophysicist in California says the San Andreas fault could be triggered into rupturing by the smaller San Jacinto fault nearby, causing a single devastating earthquake. Such a “joint rupture” may have happened before—and it could very well happen again.
At a big seismic summit yesterday at the White House, the federal government reaffirmed its commitment to creating an early warning system for earthquakes. A great new video shows exactly how this might work—and illustrates how it could help save lives.
The sounds bamboo chopsticks emit when they’re snapped in half are remarkably similar to the laws that govern the magnitude and frequency of earthquakes. Such insights could one day help engineers determine more precisely when a bridge or dam, for instance, might be about to fail.
Shortly after Apollo 16 blasted off from Florida in 1972, the Saturn V Booster was used as an experiment in and of itself, to measure seismic activity within the moon. Now, the crash site has been found.
When seismology became a global science, researchers realized that there was something weird about how earthquakes traveled through the ground. At first they thought the weirdness was due to a liquid core. This drawing proved they were half right.
