Hundreds of Quakes Are Rattling Yellowstone: DENVER — In the last two weeks, more than 100 mostly tiny earthquakes a day, on average, have rattled a remote area ofYellowstone National Park in Wyoming, putting scientists who monitor the park’s strange and volatile geology on alert.

Researchers say that for now, the earthquake cluster, or swarm — the second-largest ever recorded in the park — is more a cause for curiosity than alarm. The quake zone, about 10 miles northwest of the Old Faithful geyser, has shown little indication, they said, of building toward a larger event, like a volcanic eruption of the type that last ravaged the Yellowstone region tens of thousands of years ago. Bron: The New York Times
