Pavlof Eruption Intensifies

Alaska’s Pavlof Volcano ejects a plume 28,000 feet asl

Pavlof is erupting vigorously, exhibiting strongest seismic activity detected so far this year, characterized by intense, continuous tremor and intermittent explosions suggesting lava fountaining and ash production, Alaska Volcanoes Observatory (AVO) reported.

The wave of intense activity started late on Monday and continued into Tuesday, with trace ash fall reported in the community of King Cove about 30 miles southwest of the volcano.

AVO Daily Update  – Tuesday, June 25, 2013 @ 12:33 PM AKDT (Tuesday, June 25, 2013 @ 20:33 UTC)

PAVLOF VOLCANO (CAVW #1102-03-)
55°25’2″ N 161°53’37” W, Summit Elevation 8261 ft (2,518 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code:   ORANGE
In its daily briefing AVO said:

Vigorous eruptive activity indicated by a distinct increase in seismicity beginning around 6:50 UTC (22:50 AKDT) last evening is continuing. The level of seismicity for the past 11-12 hours has been the strongest seismic activity detected so far during the 2013 eruption of Pavlof Volcano. The seismicity is characterized by intense, continuous tremor and intermittent small explosions that are likely associated with lava fountaining and ash production.

• A distinct plume extending to the west of the volcano rising as high 28,000 feet above sea level (a.s.l.) according to Satellite data and pilot reports.

• Satellite imagery also show strong thermal signals at the volcano summit.

• AVO received a report of trace ash fall on the community of King Cove about 30 miles southwest of the volcano on June 25, 2013.

At this level of unrest it is likely that lava fountaining and ash emission are occurring. Lava fountaining is likely producing spatter-fed lava flows that are descending the flanks of the volcano over ice and snow and could be producing substantial steam plumes. These plumes probably contain variable amounts of ash. At the level of unrest observed over the past 11-12 hours, the volcanic plume has not been particularly ash rich; however, this could change if the character of the eruption changes and it remains possible for more robust ash plumes to be generated at any time. AVO is monitoring the eruption closely and will issue further information as it becomes available.

Mount Pavlof, one of the most active volcanoes in the U.S.,  has been erupting since May 13, spewing ash and lava at a low intensity.

Veniaminof Volcano Activity [Source: AVO]

Continued volcanic tremors  suggest that the Veniaminof Volcano is still erupting, said AVO. Recent satellite images  show elevated surface temperatures at the intracaldera cone; webcam images from Perryville show a light-colored plume rising above the rim of the intracaldera cone, some 8,200 feet a.s.l.

It is possible for activity at Veniaminof Volcano to increase above its current level at any time and more vigorous ash emissions may result. Sustained periods of volcanic tremor may correspond with continuous ash emission which may not be detected in satellite data, especially if ash plumes remain below 15,000 to 20,000 feet above sea level. Brief bursts of ash emission and small explosions with ash fall limited to areas on the flanks of the volcano are likely to occur while the volcano is at its current level of unrest. A larger explosive episode and associated ash emission is not expected at the current level of unrest; however, this remains possible and would be evident in seismic and satellite data.

DISASTER Diary – 21 May 2013

Major Disaster Declared in Oklahoma after Mega Tornado Kills Dozens

The Disaster President has declared a major disaster exists in the State of Oklahoma in the area affected by severe storms and tornadoes beginning on May 18, 2013, and continuing.

The areas worst affected are the counties of Cleveland, Lincoln, McClain, Oklahoma, and Pottawatomie.

At least 91 people, many of them children, are feared to have been killed and about 240 others injured after a mega tornado ripped through Oklahoma City suburbs, leveling numerous blocks in the city of Moore (pop: ~ 55,000),  Cleveland County, Oklahoma.

The death toll included 51 confirmed deaths and an additional 40 bodies on their way to the Medical Examiner’s office. (See also the ‘Joplin Syndrome’).

• The tornado was rated as at least an EF4, with winds of up to 200mph, according to NWS preliminary damage ratings.
• The tornadic event began at 2.56pm CDT on Monday and lasted for 40 minutes.
• Moore twister was as much as two miles wide, and carved a 20-mile path of destruction.
• The tornado left obliterated many hundreds of homes and other buildings in Moore.

This is a preliminary tornado track for the tornado that affected Newcastle, Moore, and Oklahoma City on May 20, 2013. The tornado touchdown at around 2:56 pm in Newcastle, OK and moved through Moore and south OKC before lifting at around 3:36 pm. The path length is estimated to be about 20 miles long with a preliminary damage rating of at least EF4. —NWS

“Our hearts are broken,” Oklahoma Gov. Mary Fallin said. “This is bigger than anything I’ve ever seen. It’s absolutely huge. It’s horrific.”

More Severe Weather Expected from Great Lakes to Central Texas on Tuesday

More severe weather is expected on Tuesday from the Great Lakes across the Mississippi River Valley and into central Texas. Primary threats will be very large hail, damaging winds and tornadoes. Some of the storms could also produce heavy rainfall leading to flash flooding concerns, especially in the Ark-La-Tex region. —NWS

Satellite Images of Recent Volcanic Activities

Recent Activity at Shiveluch Volcano

Shiveluch Volcano on Russia’s Kamchatka Peninsula ejected a plume of ash, volcanic gases and steam, while dark rivulets flowed down the volcano’s snowy slopes. The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA’s Terra satellite captured this image on February 13, 2010. Dark flows on the snowy slopes could result from lava and/or lahars—avalanches of water and mud likely prompted by heat from the summit.

Shiveluch is among Kamchatka’s most active volcanoes. In mid-February 2010, the Alaska Volcano Observatory reported that activity at Shiveluch had been elevated above background levels for days, including a lava flow as well as ash plumes reaching an altitude of 5.2 kilometers (17,060 feet).

Partial Dome Collapse at Soufriere Hills

Soufrière Hills Volcano on the Caribbean island of Montserrat experienced a partial dome collapse on February 11, 2010 at 12:35 pm local time. Lasting nearly an hour, the event sent a plume 15 km (50,000 feet) skyward, and sent pyroclastic flows—avalanches of hot gas and debris—some 300 to 400 meters (980 to 1,200 feet) out to sea. The pyroclastic flows destroyed many buildings in the village of Harris north of Sourfrière Hills, and the Montserrat Volcano Observatory described the dome collapse as the most severe incident since May 2006.

The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured this true-color image on February 11, 2010, the same afternoon that the dome collapsed. An east-west volcanic plume completely obscures the island of Montserrat, casting a shadow toward the northeast. Two smaller, fainter plumes also extend from the island, one to the north and the other to the south. The northern plume lies in the shadow of the east-west plume and consequently must occur at a lower altitude. NASA image by Jeff Schmaltz, MODIS Rapid Response Team  at NASA GSFC.

Before the volcano became active in July 1995, about 5,000 people lived in Plymouth, located 4 km west of English’s Crater. During the first two years of the eruption, ash and noxious gas from explosions and pyroclastic flows frequently settled on Plymouth. On August 3, about 3 weeks after this image was taken, the first significant pyroclastic flow swept through the evacuated town. The flow triggered many fires and caused extensive damage to buildings and community facilities by direct impact and burial. Date: 12 July 1997. Credit: R.P. Hoblitt/ USGS

Tao-Rusyr Caldera

Tao-Rusyr Caldera, Onekotan Island, Kuril Islands, Kamchatka Peninsula, Russia

Latitude: 49.35°N 49°21’0″N
Longitude: 154.70°E 154°42’0″E

The huge Tao-Rusyr caldera on southern Onekotan Island is one of the most spectacular volcanoes of the Kuril Islands off the southern tip of Russia’s Kamchatka Peninsula.  The 7.5-km-wide caldera was formed about 7500 years ago during a catastrophic volcanic eruption, one of the largest Holocene eruptions in the Kuril Islands. Today, the basaltic-to-andesitic ancient Tao-Rusyr Caldera is filled by the deep blue waters of Kal’tsevoe Lake, whose surface is 400 m above sea level.

A large symmetrical post-caldera cone, 1325-m-high andesitic Krenitzyn Peak, forms a 4-km wide island that towers high above the caldera rim and fills the NW portion of the caldera lake. A 350-m-wide, 100-m-deep crater truncates the peak and a large lateral crater is located on the upper NE side.

The Advanced Land Imager (ALI) on NASA’s Earth Observing-1 (EO-1) satellite acquired this true-color image of southern Onekotan on June 10, 2009. In this late-spring shot, snow or ice lingers on the land, forming white streaks on a brown-and-green land surface. In the northwest quadrant of the caldera is Krenitzyn Peak, which rises to a height of 1,325 meters (4,347 feet).

Like the other Kuril Islands, Onekotan lies along the Pacific Ring of Fire. The Kuril Island volcanoes are fueled by magma generated by the subduction of the Pacific Plate under the Eurasian Plate, which takes place along a deep trench about 200 kilometers (120 miles) to the islands’ east. The only historical eruption at Krenitzyn Peak occurred in 1952, a week after a magnitude 9.0 earthquake along the subduction fault.

A large symmetrical post-caldera cone, 1325-m-high Krenitzyn Peak, forms a 4-km wide island that towers above the rim of 7.5-km-wide Tao-Rusyr caldera. A 350-m-wide crater caps the peak, and a large shallow lateral crater (left center) is located on the upper NE flank. The small dark mass along the eastern shoreline (right-center) is a lava dome that was emplaced in 1952 during the only historical eruption of the volcano. Kal’tsevoe lake fills a caldera that was formed about 7500 years ago during one of the largest Holocene eruptions in the Kuril Islands.

Bezymianny Volcano on Russia’s Kamchatka peninsula erupts

PETROPAVLOVSK-KAMCHATSKY. The Bezymianny Volcano on Russia’s Kamchatka peninsula has erupted, Itar-Tass reported.

During the period of unrest, it emitted an ash column with a diameter of about 100 km.

The eruption was forecast prior to the unrest. The Bezymianny Volcano (2,800m high) is one of 28 active volcanoes on the peninsula. Bezymianny erupts explosively once or twice each year. The eruptions can last up to several days.

During its most powerful eruption in 1956, Bezymianny dome exploded collapsing about 280m of its summit (reduced from 3080 to 2800m). It ejected about one cubic kilometer volcanic debris in a very short time. [See VEI below.]
