Geologists Issue Quake Warning
Kelly Incidents prompt Geologists To Alert Public
Geologists issued a rare earthquake alert this week after a
swarm of quakes was detected near kelly and the famous
Steamboat Geyser erupted in Yellowstone NP.
Geologists of Jackson Hole, a coalition of professionals, said a
recent "swarm" of small quakes near kelly, plus changes in
springs at the National Fish hatchery, caused them to tell the
public of undeground events. Their statement, issued Monday,
came as Yellowstone officials announced Friday's eruption of
Steamboat Geyser, the tallest in the world. In addition, geologist
said there have been reports of peculiar odors and increased
gases in wells and ponds "and the curious flow stop and restart
at the National Fish Hatchery Spring."
The quake swarm involved 31 small quakes of magnitude two
and greater located one and a half to three miles south of kelly
since January 1.That's a big increase from the 25 quakes
recorded within six miles of the area in the previous 25 years,
from 1986 to 2001.
In Yellowstone, nobody witnessed Steamboat erupt park
spokeswoman Cheryl Matthews said. A geyser gazer - one of a
number of volunteers who track eruptions - is still probably
kicking himself for leaving the Norris Geyser Basin at 6 PM Friday,
within two hours of when Steamboat likely went off, Matthews
Matthews said Dr. Bob Smith, (A Geologist), at the University of
Utah is looking to see whether the eruption was associated with
any quakes. ......
