They were able to identify nearly 500 additional fault lines that could produce damaging earthquakes. In the last 200 years, 37 U.S. states have seen earthquakes exceeding magnitude 5, "highlighting a long history of seismic activity across this country," the USGS said. Which areas are most a...
Geologists initially blamed the earthquake on the movement of the Caribbean tectonic plate eastward along theEnriquillo–Plantain Garden (EPG) strike-slip fault system. However, when no surfacedeformationwas observed, the rupturing of the main strand of the fault system was ruled out as a cause. ...

The United States Geological Survey (USGS) carries out an extensive program of seismic, geodetic, and geologic studies in California that may be relevant to designing new experiments on the North Anatolian Fault Zone. A telemetered microearthquake network of ~350 stations monitors seismicity down to...
There's a major fault linein New Jersey called the Ramapo Fault, which stems from the Appalachian mountains, and there are at least five smaller fault lines under Manhattan island. The quake comes just a few months after the USGS warned nearly75% of the United States could face damaging qua...
to Fantastic Pit in the first place requires navigating through a labyrinth of other, smaller pits. But for cavers who have the experience—or are willing to learn vertical caving skills—it's a rare opportunity to drop through the deepest cave pit (that we know of) in the United States....

There are only about 15 earthquakes that reach the 7.0 magnitude range per year, according to CNN’s Chad Myers and the United States Geological Survey. “But they typically don’t happen so close to land; this one was not very far offshore,” Myers said. He added that a 7.0-magnitu...
