## Volcano Hazard Warning Products from the Alaska Volcano Observatory (AVO)

**Volcano Hazard Warning Products from the Alaska Volcano Observatory (AVO)**

*The Alaska Volcano Observatory is a cooperative program of the U.S. Geological Survey, *
*the University of Alaska Fairbanks Geophysical Institute, and the Alaska Division of *
*Geological and Geophysical Surveys*

## AVO Role

- Understand the eruptive history, style of eruption, and hazards of Alaska’s volcanoes
- Systematically monitor dangerous volcanoes and look for signs of unrest
- Issue warnings and announcements about unrest, eruptions, evaluating false eruption reports, and announcing cessation of eruptions
- During eruptions, provide frequent updates on the level of activity, the evolving hazard; work with NWS, FAA and others to track the ash cloud and other impacts

## Volcanic Activity Notifications and other resources

- Weekly Update
- Information Release
- Status Report
- Email, fax, web dissemination
- As needed, web only updates during eruptions
- Web page data base and resources
- AVO’s flexibility allows us to be (more) creative than formal products from NWS and FAA

## Weekly Update

**ALASKA VOLCANO OBSERVATORY****Weekly Update****Friday, May 11, 2007 1:15 PM AKDT (2115 UTC)**
**KOROVIN VOLCANO (ATKA ISLAND) **(CAVW#1101-16)52°22'48" N174°9'22" W, Summit Elevation 5030 ft (1533 m)Current Aviation Color Code: **YELLOW**Current Volcanic Activity Alert Level: **Advisory**Intermittent, low-level seismic activity continues at _[Korovin](http://www.avo.alaska.edu/volcanoes/volcinfo.php?volcname=Korovin)_. Clouds obscured views of the volcano by satellite all week.Korovin Volcano is a 1553-m-high (5030 ft) stratovolcano located on the northern part of _[Atka](http://www.avo.alaska.edu/volcanoes/volcinfo.php?volcname=Atka)_ Island in the central Aleutian Islands, about 184 km (110 mi) east of Adak, 538 km (350 mi) west of Dutch Harbor, and 1760 km (1100 mi) southwest of AnchorageKorovin has erupted several times in the past 200 years, including 1907, 1951, 1953, 1954, 1973, 1976, 1986, 1987, 1996, and 1998. All of these eruptions produced minor amounts of ash and occasional but small lava flows. Reports of the height of the ash plume produced by the 1998 eruption ranged from 4900 to 9200 m (16,000 to 30,000 feet) above sea level. **OTHER ALASKA VOLCANOES**Seismic activity is monitored in real time at 31 volcanoes in Alaska. Satellite images of all Alaskan volcanoes are analyzed daily for evidence of ash plumes and elevated surface temperatures. Some volcanoes may currently display anomalous behavior but are not considered to be at a dangerous level of unrest. _[Wrangell](http://www.avo.alaska.edu/volcanoes/volcinfo.php?volcname=Wrangell)_, _[Spurr](http://www.avo.alaska.edu/volcanoes/volcinfo.php?volcname=Spurr)_, _[Redoubt](http://www.avo.alaska.edu/volcanoes/volcinfo.php?volcname=Redoubt)_, _[Iliamna](http://www.avo.alaska.edu/volcanoes/volcinfo.php?volcname=Iliamna)_, _[Augustine](http://www.avo.alaska.edu/volcanoes/volcinfo.php?volcname=Augustine)_, _[Snowy](http://www.avo.alaska.edu/volcanoes/volcinfo.php?volcname=Snowy)_, _[Griggs](http://www.avo.alaska.edu/volcanoes/volcinfo.php?volcname=Griggs)_, Katmai, _[Novarupta](http://www.avo.alaska.edu/volcanoes/volcinfo.php?volcname=Novarupta)_, _[Trident](http://www.avo.alaska.edu/volcanoes/volcinfo.php?volcname=Trident)_, _[Mageik](http://www.avo.alaska.edu/volcanoes/volcinfo.php?volcname=Mageik)_, _[Martin](http://www.avo.alaska.edu/volcanoes/volcinfo.php?volcname=Martin)_, _[Ugashik-Peulik](http://www.avo.alaska.edu/volcanoes/volcinfo.php?volcname=Ugashik-Peulik)_, _[Ukinrek Maars](http://www.avo.alaska.edu/volcanoes/volcinfo.php?volcname=Ukinrek%20Maars)_, _[Aniakchak](http://www.avo.alaska.edu/volcanoes/volcinfo.php?volcname=Aniakchak)_, _[Veniaminof](http://www.avo.alaska.edu/volcanoes/volcinfo.php?volcname=Veniaminof)_, _[Pavlof](http://www.avo.alaska.edu/volcanoes/volcinfo.php?volcname=Pavlof)_, _[Dutton](http://www.avo.alaska.edu/volcanoes/volcinfo.php?volcname=Dutton)_, _[Isanotski](http://www.avo.alaska.edu/volcanoes/volcinfo.php?volcname=Isanotski)_, _[Shishaldin](http://www.avo.alaska.edu/volcanoes/volcinfo.php?volcname=Shishaldin)_, _[Fisher](http://www.avo.alaska.edu/volcanoes/volcinfo.php?volcname=Fisher)_, _[Westdahl](http://www.avo.alaska.edu/volcanoes/volcinfo.php?volcname=Westdahl)_, _[Akutan](http://www.avo.alaska.edu/volcanoes/volcinfo.php?volcname=Akutan)_, _[Makushin](http://www.avo.alaska.edu/volcanoes/volcinfo.php?volcname=Makushin)_, _[Okmok](http://www.avo.alaska.edu/volcanoes/volcinfo.php?volcname=Okmok)_, _[Great Sitkin](http://www.avo.alaska.edu/volcanoes/volcinfo.php?volcname=Great%20Sitkin)_, Kanaga, Tanaga, and Gareloi volcanoes are at Aviation Color Code **GREEN** and Volcanic Activity Alert Level NORMAL. All are at or near normal levels of background seismicity. AVO did not detect ash plumes or significant elevated surface temperatures in the vicinity of any volcano.

## Information Release

**ALASKA VOLCANO OBSERVATORY****INFORMATION RELEASE****Tuesday, January 17, 2006 8:00 AM AKST (1700 UTC)**
**AUGUSTINE VOLCANO** (CAVW#1103-01-)59.3633°N 153.4333°W, Summit Elevation 4134 ft (1260 m)Current Level of Concern Color Code: **RED**A strong seismic signal began at approximately 7:58 AST, marking an the onset of an explosive eruption of Augustine. We are changing the level of concern color code from **ORANGE** to **RED**. AVO is monitoring the situation closely and will issue further updates as new information and analyses become available.

## Daily Status Report

**ALASKA VOLCANO OBSERVATORY****Current Status Report****Monday, May 14, 2007 11:50 AM AKDT (1950 UTC)**
**KOROVIN VOLCANO (ATKA ISLAND) **(CAVW#1101-16)52°22'48" N174°9'22" W, Summit Elevation 5030 ft (1533 m)Current Aviation Color Code: **YELLOW**Current Volcanic Activity Alert Level: **Advisory**Intermittent, low-level seismic activity continues at Korovin. Clouds obscured views of the volcano by satellite today.Korovin has erupted several times in the past 200 years, most recently in 1998. Eruptions typically produce minor amounts of ash and occasional, small lava flows. Ash plume heights could exceed 20,000 ft above sea level. Korovin occasionally produces large steam plumes from its summit.**CLEVELAND VOLCANO **(CAVW#1101-24-)52°49'20" N169°56'42" W, Summit Elevation 5676 ft (1730 m)Current Aviation Color Code: **YELLOW**Current Volcanic Activity Alert Level: **Advisory**Clouds obscured views of Cleveland by satellite today. AVO has received no new information about activity at Cleveland. The lack of a real-time seismic network at Cleveland means that AVO is unable to track local earthquake activity related to volcanic unrest. Short-lived explosions with ash plumes that could exceed 20,000 ft above sea level can occur without warning and may go undetected on satellite imagery.VOLCANO INFORMATION ON THE INTERNET: http://www.avo.alaska.eduRECORDING ON THE STATUS OF ALASKA'S VOLCANOES (907) 786-7478

## Information Releases

- Kamchatkan and Northern Kuriles Volcanic ActivityKVERT INFORMATION RELEASE 17-07Sunday, May 13, 2007, 21:20 KDT (08:20 UTC)BEZYMIANNY VOLCANO: 55°58'N, 160°36'E; Elevation 2,895 mCURRENT LEVEL OF CONCERN COLOR CODE IS **ORANGE**Growth of the lava dome continues. The activity of the volcano could affect low-flying aircraft in the vicinity of the volcano.According to seismic data from Kozyrevsk, probably the explosive eruption occurred at Bezymianny volcano from 14:30 till 15:00 UTC on May 11. According to satellite data, an ash plume extended to the north from the volcano. The ash fall was observed at Klyuchi from about 16:00 UTC till ~22:00 on May 11. Because the eruption of Klyuchevskoy volcano continued too ash deposits at Klyuchi were a mix of ash from Bezymianny and a small part (as addition) of ash from Klyuchevskoy. According to satellite data, large plumes different directions were observed over the Northern Kamchatka from 16:00 UTC on May 11. According to visual data from Kozyrevsk, at 22:30 UTC on May 11, there was one of hot avalanches that happens after the eruption. Ash plume rose up to 4.0 km ASL. According to satellite data, a long thermal anomaly (11 pixels in size) extending to the south-east from the lava dome was noted at 18:58 UTC on May 12 (NOAA-15). Probably this anomaly reflection hot deposits of pyroclastic flow.Clouds obscured the volcano several last days.IF YOU HAVE ANY QUESTIONS OR CONCERNS, PLEASE CONTACT:Olga Girina, KVERT, IVS FED RASE-mail: girina@kscnet.ruTel.
