ALASKA VOLCANO OBSERVATORY

CURRENT STATUS REPORT

Saturday, July 15, 2006 12:00 PM AKDT (2000 UTC)




AUGUSTINE VOLCANO (CAVW#1103-01-)

59°21'48"N 153°26'W , Summit Elevation 4134 ft (1260 m)

Current Level of Concern Color Code: YELLOW



Seismicity at Augustine remains low. Partly cloudy webcam views today show the usual steam plume.



Rockfalls and avalanches of hot debris from the cooling lava dome and flows can still occur with little or no warning. These events produce small, localized ash plumes. Larger rockfalls can produce block and ash flows or avalanches that are hazardous to anything in their path. Airborne ash from these events, however, is not likely to travel much beyond Augustine Island.



VENIAMINOF VOLCANO (CAVW#1102-07-)

56°11'44"N 159°23'18"W , Summit Elevation 8225 ft (2507 m)

Current Level of Concern Color Code: YELLOW



Seismicity at Veniaminof remains low. Partly cloudy webcam views continue to show a white steam plume.



Intermittent, short-lived, very small-volume steam and ash bursts from the intracaldera cone have been common over the past few years. Ash from these events is not likely to extend beyond the caldera rim. There are no indications that a larger eruption is imminent.

VOLCANO ALERT LEVELS
NORMAL
Volcano is in typical background, noneruptive state or, after a change from a higher level, volcanic activity has ceased and volcano has returned to noneruptive background state.
ADVISORY
Volcano is exhibiting signs of elevated unrest above known background level or, after a change from a higher level, volcanic activity has decreased significantly but continues to be closely monitored for possible renewed increase.
WATCH
Volcano is exhibiting heightened or escalating unrest with increased potential of eruption, timeframe uncertain, OR eruption is underway but poses limited hazards.
WARNING
Hazardous eruption is imminent, underway, or suspected.

AVIATION COLOR CODES
GREEN
Volcano is in typical background, noneruptive state or, after a change from a higher level, volcanic activity has ceased and volcano has returned to noneruptive background state.
YELLOW
Volcano is exhibiting signs of elevated unrest above known background level or, after a change from a higher level, volcanic activity has decreased significantly but continues to be closely monitored for possible renewed increase.
ORANGE
Volcano is exhibiting heightened or escalating unrest with increased potential of eruption, timeframe uncertain, OR eruption is underway with no or minor volcanic-ash emissions [ash-plume height specified, if possible].
RED
Eruption is imminent with significant emission of volcanic ash into the atmosphere likely OR eruption is underway or suspected with significant emission of volcanic ash into the atmosphere [ash-plume height specified, if possible].
