Arctic Quake Sends Waves Through Nevada

 CBS 5 Earthquake Section

NORTH FORK, Nev. (AP) ― Scientists say what appeared to be an earthquake in northeastern Nevada was actually a seismograph picking up waves from an earlier quake in the Arctic Ocean.

A preliminary report from the U.S. Geological Survey had said a magnitude-4.2 temblor centered about 18 miles west of North Fork shook Elko County at 3:07 a.m. Tuesday morning.

USGS geophysicist Jessica Sigala says a seismologist reviewed the event and determined that phases from a magnitude-5.8 quake in the Arctic Ocean seven minutes earlier had been wrongly interpreted by a seismograph as a local quake.

Sigala says shaking could not be felt in Nevada, but that waves from a quake like the one in the Arctic can be detected around the world.
