Man-made earthquakes, a side effect of some high-tech energy drilling, cause less shaking and in general are about 16 times weaker than natural earthquakes with the same magnitude, a new U.S. study found.
It is not unusual for swarms of small earthquakes to precede a volcanic eruption. They can reach a point of such rapid succession that they create a signal called harmonic tremor that resembles sound made by various types ...
A mega-quake in 1255 that wrecked the Nepalese capital, wiped out a third of the population of Kathmandu Valley and killed the country's monarch, King Abhaya Malla, was of a kind that may return to the Himalayas, seismologists ...
The magnitude-4.0 earthquake that rattled people awake across the Puget Sound region last Wednesday probably struck on the western edge of the Seattle Fault, according to geologists.
Sumatra quake was part of crustal plate breakup: Study shows huge jolt measured 8.7, ripped at least 4 faults
Seismologists have known for years that the Indo-Australian plate of Earth's crust is slowly breaking apart, but they saw it in action last April when at least four faults broke in a magnitude-8.7 earthquake that may be the ...
The U.S. Geological Survey has recorded seven small earthquakes shaking central Oklahoma in a span of about 14 hours.
(AP)—Seismologists in Alaska say earthquakes have jolted four different parts of the state in the last 12 hours.
If a monster earthquake struck off Alaska's coast, tsunami waves would rush toward California, crippling the nation's busiest port complex and flooding coastal communities, a report released Wednesday suggests.
Two moderate earthquakes have struck central California, one of which was widely felt across the region.
Monitoring slow earthquakes may provide a basis for reliable prediction in areas where slow quakes trigger normal earthquakes, according to Penn State geoscientists.
