Alaska Volcanoes Update

Friday, January 3, 1997, 12:00 noon AST (2100 UTC)

Pavlof Volcano: 55.42N, 161.9W 8,262 ft elevation

CURRENT LEVEL OF CONCERN CODE IS YELLOW

The eruption at Pavlof Volcano is intermittent and much reduced

from the vigorous activity of last weekend. Seismicity has

remained low and clouds have obscured the volcano for much of

the week. This morning, however, a National Weather Service

observer in Cold Bay spotted a small burst of ash rising just

above the summit of the volcano.



A pilot report yesterday also noted steam and ash drifting south from

the summit. Based on the previous pattern of eruptive

activity at Pavlof, a resumption of more energetic ash and lava

emission could resume with little or no warning. AVO continues to

monitor the volcano closely and will issue further updates as the

situation changes.



Pavlof is located 600 miles southwest of Anchorage. The nearest towns

to the volcano are Cold Bay (37 mi SW), King Cover (30 mi SW),

Sand Point (60 mi E), and Nelson Lagoon (50 mi NE). AVO has a

seismic network of six stations near the volcano. (repeated in

subsequent updates)



Other volcanoes:

Seismic activity is monitored in real time at the following volcanoes.

Some of the volcanoes listed below may have anomalous

seismicity as noted, but are not considered to be at a dangerous

level of unrest. (repeated in subsequent updates)

Spurr, Redoubt, Augustine, Griggs, Katmai, Trident, Mageik, Martin,

Dutton, Akutan, and Makushin volcanoes are all at or near

normal levels of background seismicity. (repeated in subsequent

updates)

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].
