Scientists report in the journal Nature that the distribution of
altered rocks within Mount Rainier volcano is much more restricted
than previously described. By using high-resolution helicopter-borne
electromagnetic and magnetic sensors and recent geologic mapping
of the volcano, USGS scientists found that an appreciable volume
of mostly buried altered rocks is mainly on the west flank of
Mount Rainier beneath Sunset Amphitheater. See details
of this work.

Scientists have completed the installation of the most sensitive
instruments available for monitoring the strain deep beneath the
surface of a volcano. Three sites on Mauna Loa and one on Kilauea
volcanoes in Hawai`i now have an ultra-sensitive strainmeter and a
seismic package consisting of a three-component broadband seismometer and
a strong-motion sensor. See details
of this work from the USGS Hawaiian Volcano Observatory.

(8/15/2000)
Using the latest multibeam sidescan sonar technology, scientists
from the U.S. Geological Survey and the University of New Hampshire
finished mapping
the bottom of Crater Lake, Oregon, in
Crater Lake National Park.

(12/17/1999)
Lava erupted from Kilauea Volcano finally reached
the sea again on December 13, three months after the supply of magma
to the volcano's vent, the Pu`u `O`o cinder and spatter cone, was briefly
shut off on September 12.

(11/10/1999)
USGS
scientists participate in an
emergency-communication exercise regarding an eruption
in Long Valley caldera, California. The exercise used a
hypothetical eruption from along the Mono-Inyo Craters volcanic
chain to test the emergency communication systems and pathways
between government agencies and private industry.
-
(5/19/1999) Using data from newly installed seismometers
and from civilian meteorological satellites, scientists of the
Alaska Volcano Observatory tracked an increasing
unrest Shishaldin Volcano for 2 1/2 months and issued several
eruption warnings. The warnings were based on analysis of data
from new seismic stations installed near the volcano.
-
(2/5/1999) A two-year
cooperative
pilot project is under way to develop, deploy, and begin operation of
an automated system to detect the occurrence of a lahar in the Puyallup
River valley, downstream from Mount Rainier volcano in Washington.
-
(12/11/1998) A new report provides summary information about the
historically
active volcanoes of Alaska.
-
(10/2/1998) A new report summarizes the
volcano hazards at Crater Lake, Oregon.
-
(4/28/98) In the next few months, scientists plan to expand several volcano-monitoring
networks in order to better track volcanic unrest in the United
States.
-
(2/25/1998) A recent four-day swarm of small earthquakes beneath
Mount Hood, Oregon, is typical for the volcano based on
earthquakes recorded in the past 20 years. The volcano remains
quiet and no other signs of activity have been detected.
-
(1/15/1998) Scientists are closely monitoring the continued
unrest at Long Valley caldera in California. This document provides
a summary of what's going on there and provides anchors to monitoring
information available on line.
-
(1/3/1998) Scientists mark the 15-year eruption anniversary of
Kilauea Volcano on the Island of Hawaii with a summary, The Pu`u `O`o-Kupaianaha eruption:
still flowing after all these years! This article appeared in
the 1/4/98 edition of the Hawaii Tribune-Herald as part of the weekly
Volcano Watch articles written by scientists of the USGS Hawaiian
Volcano Observatory.
-
(12/4/1997) A new report
on Newberry volcano, located 40 km south of Bend, Oregon, describes the
potential hazards from future eruptions of one of the largest volcanoes
in the Cascade Range of the Pacific Northwest.
-
(10/2/1997) The longest-lasting
east rift eruption of Kilauea Volcano in the past 200 years
continues.
-
USGS scientists conduct the Mammoth
'97 experiment to help answer unresolved questions about the
geologic structures and ongoing activity in the Long Valley caldera
-
USGS scientists spotlight volcano
hazards for educators and the public in Washington and Hawaii
-
USGS scientists continue to work with scientists in Mexico and
Montserrat to help reduce the risk from eruptions at Popocatépetl and
Soufriére Hills volcanoes and to gain new experience in
monitoring potentially explosive volcanoes.
-
Expanded volcano monitoring network along Alaska's Aleutian
Island chain
-
Is Mount Hood Volcano a potentially
dangerous volcano? A new report explains how future volcanic
activity of Mount Hood in southwestern Oregon is likely to affect
nearby communities and recreation areas.
