All shook up!An earthquake in Alaska didn't just rock the locals. It caused a shake-up 3,100 kilometers (2,000 miles) away in Yellowstone National Park Yellowstone National Park, 2,219,791 acres (899,015 hectares), the world's first national park (est. 1872), NW Wyo., extending into Montana and Idaho. It lies mainly on a broad plateau in the Rocky Mts., on the Continental Divide, c. . Scientists found that the quake jolted the park's geysers The examples and perspective in this USA may not represent a worldwide view of the subject. Please [ improve this article] or discuss the issue on the talk page. This is an alphabetical list of notable geysers, a type of erupting hot spring: Alaska's Denali fault (boundary along which rocks slide past each other) suddenly shifted, generating powerful seismic waves (vibrating vibrating, v using quivering hand motions made across the client's body for therapeutic purposes. energy waves that travel through the ground). The fault sent its shuddering waves on a collision course with the Western U.S. "[Yellowstone] happened to be right in the path," says Robert Christiansen of the U.S. Geological Survey. The vibrations passed through the park. Hundreds of smaller local quakes were triggered, rattling underground cracks that feed hot water to the park's geysers. "Geysers are very sensitive to changes in their underground plumbing systems," says Henry Heasler, Yellowstone's park geologist. The rattling loosened minerals that block pipes and keep eruptions in check. Result: Some geysers blew their tops more often, and others less frequently. But one famous geyser geyser (gī`zər) [Icel.], hot spring from which water and steam are ejected periodically to heights ranging from a few to several hundred feet. was unfazed un·fazed adj. Not fazed or disturbed. . Old Faithful lived up to its name--erupting right on schedule. |
