Remote Alaska volcano might erupt soon, experts say


Alaska's Cleveland Volcano could soon be leaking from its flanks if the lava inside continues to build up, officials at the Alaska Volcano Observatory reported.

The observatory reported that the volcano's lava dome was 262 feet in diameter on August 30 and has now expanded to 394 feet.

"The presence of the lava dome increases the possibility of an explosive eruption, but does not necessarily indicate that one will occur," the observatory said. "Short-lived explosions could produce an ash cloud that exceeds 20,000 ft above sea level......"

Cleveland Activity - Color Code ORANGE : Alert Level WATCH


2011-09-06 16:08:56 - VAN/VONA:

Observations of Cleveland Volcano from Tuesday September 6, 2011 show that the small lava dome in the summit crater has resumed growth and now fills the floor of the crater. In response, AVO is raising the Aviation Color Code to Orange and the Alert Level to Watch.

A persistent thermal anomaly has been observed since September 3, probably marking the timing of resumed lava dome growth. The size of the dome as of August 30 when it appeared to have stopped growing was approximately 80 meters (262 feet)in diameter. The current dome is approximately 120 meters (394 feet) in diameter. If dome growth continues, lava flows onto the flanks of the volcano may develop but would not be hazardous to aviation. The presence of the lava dome increases the possibility of an explosive eruption, but does not necessarily indicate that one will occur. Short-lived explosions could produce an ash cloud that exceeds 20,000 ft above sea level. These events can occur without warning and may go undetected in satellite imagery for hours.

Mount Cleveland Volcano Continues Building Massive Dome

A persistent thermal anomaly has been observed since September 3, probably marking the timing of resumed lava dome growth. The size of the dome as of August 30 when it appeared to have stopped growing was approximately 262 feet in diameter. The current dome is approximately 394 feet in diameter. If dome growth continues, lava flows onto the flanks of the volcano may develop but would not be hazardous to aviation....

Yeah, but a lot of the fallout would affect native folks in the area that are already having a bad year. Many have a subsistence existence (live off the land). It has already been gloomy and rainy all summer this year where I work part time in SW AK, so they sure don't need any more gloom. Things not growing well as it is.

Over the past 24 hours, satellite views of Cleveland have been obscured by clouds.

A persistent thermal anomaly was observed September 3-6, indicating lava dome growth. If dome growth continues, lava flows onto the flanks of the volcano may develop but would not be hazardous to aviation. The presence of the lava dome increases the possibility of an explosive eruption, but does not necessarily indicate that one will occur. Short-lived explosions could produce an ash cloud that exceeds 20,000 ft above sea level. These events can occur without warning and may go undetected in satellite imagery for hours.

Alaska Volcano Now on Advisory Status


September 9, 2011

Based from a sattelite data by the U.S. Geological Survey (USGS), the growth of the Cleveland Volcano lava dome has stopped.

Aleutian volcano's behavior a challenge for scientists


A volcano in Alaska's Aleutian Islands has been in an unusual low-level eruption for two months, raising the spectre of an explosive eruption with little warning, officials at the Alaska Volcano Observatory said on Friday.

Scientists Concerned By Continued Eruptions At Alaskan Volcano
September 18, 2011


"The two-month long, low-level eruptions occurring at a volcano in Alaska’s Aleutian Islands have volcanologists worried that there could be a larger eruption forthcoming, Yereth Rosen of Reuters reported on Friday.

The volcano causing concern is Cleveland Volcano (also known as Mount Cleveland), a 5,676-foot peak located less about 940 miles southwest of Anchorage....."

Cleveland Volcano lava dome may be growing

The Alaska Volcano Observatory said Sunday satellite data is indicating a "thermal anomaly" at Cleveland Volcano in the Aleutian Islands, which means a lava dome at the mountain may be growing.

New picture of the lava dome has been taken.

It fills the crater now, and you can see that here:

The thermal anomaly persists at Cleveland and an explosive eruption might occur at any time with no warning. AVO has no instruments on the volcano and can’t tell what it’s going to do until it does it.

Quakes have continued to occur there in the Fox Islands, in the same area of the subduction zone all the others hit during The last six weeks. I’m not at all sure what the connection with Cleveland might be, if any, but it is interesting. Two more quakes hit there today, a 5.8 and a 5.4...well time will tell

2011-09-20 12:56:04 - Status Report



Recent observations of Cleveland volcano show that the current eruption, characterized by effusion of lava within the summit crater continues. The size of the lava dome is now about 165 m (540 ft) in diameter compared to 150 m (490 ft) in diameter on September 9,2011. The growing lava dome remains entirely contained within the summit crater but is now approximately 20 meters below the eastern rim.

To follow

Incoming CME due late 9/22 or early 9/23 could heighten activity on Cleveland.

well, we will see if this is connected

interesting stuff

Could see a large quake in this area as well.

Ionosphere has been disturbed for nearly two weeks now.

Particularly troubling is that the f-region has been periodically reaching absorption frequencies up to 15 MHz.

Cleveland volcano in Alaska showing signs of eruption
September 23, 2011

Mount Cleveland, also called the Cleveland Volcano, in the Aleutian Islands in Alaska, has been reportedly oozing lava, presaging a possible eruption.

Satellite images showed a 165 meter (541 feet) in diameter lava dome in the summit crater on Sept. 20, which increased from 150 meters (490 feet) as of Sept. 9, according to the Alaska Volcano Observatory.

Its all going on.
Thread: September the 23rd, Volcano day?
Read the stuff in my other post about volcanos.
Also the last few days there have been alot of earthquakes around the ring of fire, usually you'll only get a dozen on one side or a few small ones on either side, there has been loads the last day or two.

Lava builds in volcano on Alaska's Aleutians

ANCHORAGE, Alaska - Lava has reached the edge of a crater in a volcano in Alaska's remote Aleutian Islands, indicating the mountain could explode and send up an ash cloud that could threaten aircraft.

The Alaska Volcano Observatory says satellite images show lava at the edge of the crater rim of 5,675-foot Cleveland Mountain on uninhabited Chuginadak Island, about 940 miles southwest of Anchorage.

and here's the

Alaska Volcano Observatory

2011-10-07 11:02:33 Status Report:

The eruption of a lava dome in the summit crater of Cleveland Volcano continues. Satellite observations over the past week show that the edge of the dome is now at the level of the crater rim on the southwest and east-northeast sides, and may soon overflow the crater rim on these flanks. At present, most of the lava dome volume is contained within the summit crater, and thus not prone to gravitational collapse. No ash emissions have been detected during the current eruption which began in July, 2011, and AVO has received no other reports of activity at this volcano.

If the lava dome continues to grow in the summit crater, the possibility of an explosive event increases. With continued lava dome growth, lava may eventually overflow the crater rim to produce a lava flow and/or collapse to produce pyroclastic flows. Sudden collapse of the effusing lava could result in the generation of a volcanic ash cloud. However, lava may continue to erupt without an explosive event. It is possible that explosions from the summit crater vent could produce ash clouds that may exceed 20,000 ft above sea level. These events can occur without warning and may go undetected in satellite imagery for hours. However, lightning associated with significant ash-producing events may be detected within minutes using an automated alarm system.

The Alaska Volcano Observatory says satellite images show lava at the edge of the crater rim of 5,675-foot Cleveland Mountain on uninhabited on Chuginadak Island, about 940 miles southwest of Anchorage.

Volcano monitors say if the dome continues to grow, it could overflow the rim and increase the possibility of an explosion.

The observatory says an eruption could send up an ash cloud 20,000 feet or more.

The nearest village, Nikolski, is on another island about 50 miles east and has 18 permanent residents. The village was not considered in harm's way in previous eruptions of the volcano.
