Volcán Sheveluch, Kamchatka, Russia
Elevation: 2,800 m
Sheveluch es un stratovolcano inmenso, el más al norte de los volcanos activos en la peninsula rusa de Kamchatka. El volcán está dividido en dos partes. La parte norte es la más alta con 2.447 m, y entre ésta y la parte sudoeste hay una grieta de casi 2.000 m de profundidad. Las erupciones actuales vienen de la parte sudoeste. Las erupciones más violentas sucedieron en el 1854 y el 1964. Desde
el 1854 al 1964 la actividad ha sido continua hasta el 2006.
Así en el 1998, 1997, 1993-94, 1991, 1990, 1989, 1988, 1986-88,
1985, 1984, 1980-81, Abajo un resumen del seguimiento en los últimos tiempos Tuesday, March 29th, 2005 The height of the dome of Sheveluch volcano in Kamchatka has grown by more than 50 m during 20 days and keeps increasing, according to FEDRAS. As a result of the eruption, on February 27 the western part of Sheveluch' summit was completely destroyed. The height of the volcano diminished by more than 200 m. A powerful more than 20-kilometers-long pyroclastic flow, which destroyed the one-storeybuilding of the volcanologists' base and the seismic station, went off the giant's slope. The ash cloud spread to a distance of more than 700 km to the west of the volcano, having covered the peninsula and the adjacent water area of the Sea of Okhotsk with a strip, which was wide up to 150 km. The powerful ash deposits on the snow with an area of 310 x 150 km were clearly seen on the photographs from space provided by the AVO. The nearest neighbor of Shiveluch - Kliuchevskoi volcano - is in the state of high activity. Friday, March 25th, 2005 As of the 25th of March, the Kamchatka Volcano Eruption Response Team (KVERT) reported that the growth of the Sheveluch lava dome continues. A new lava flow is effusing at the lavadome The nearest seismic station from the volcano was destroyed by eruption February 28, 2005. Strong volcanic tremor at nearby Klyuchevskoy volcano makes it difficult to determine seismicity at Sheveluch from a seismic station at Klyuchi (45 km from the volcano). Wednesday, March 23rd, 2005 An eruption by Shiveluch has fully destroyed a camp of vulcanologists and seismic station Baidarnaya, located eight kilometers from the volcano, according to the Institute of Vulcanology and Seismology of the Far Eastern branch of the Russian Academy of Science(FEDRAS). After one/fifth of the volcano's crown caved in, a massive pyroclastic stream of lava flowed down the giant's slope more than 20 kilometers long. There were no people in the area during the event. Scientists believe that this eruption of Shiveluch was the second largest since a disastrous eruption of 1964. Monday, November 8th, 2004 Sheveluch volcano continues to eject ashes to the heights between 1,500 and 4,500 meters. According to experts from the Kamchatka scientific and methodological seismology research group, they registered a 3,000-meter-high emission at 11:05 local time on Monday
May
12th, 2004 Mud torrents flowing from the slopes of Volcano Shiveluch have reached the road that links the district centre of Ust-Kamchatsk with the rest of the region. The road is closed to all types of transport vehicles. Specialists have gone there to estimate the road situation. May 11th, 2004 According to the KVERT, the volcano began an explosive eruption at 13:00 UTC on May 9, 2004, sending a plume of ash up 8,000 meters (26,400 feet) into the atmosphere. (http://www.osei.noaa.gov/) May 1st, 2004 Ash has been ejected 2,000-5,000 meters into the air from the crater of the Shiveluch. April 27th, 2004 Shiveluch has erupted a 8,000-meter-high pillar of ash. The eruption, which took place at 7.26 a.m. local time and which was accompanied by an earthquake that lasted 4.5 minutes, produced an ash cloud, which could be seen at a height of about 1,000 m above the crater for more than an hour, reported the Kamchatka seismological expedition. Februar 27th, 2004 January 11th, 2004. Kliuchevskoi also erupting at same time, and Bezymianny few days later. March, 12th, 2003 In the past few weeks Shiveluch has been extremely active. The seismic stations register broken volcanic vibration in the cupola area. Gas and ash outbursts over the crater rise at times to a height of up to 5,000 metres. Descents of fragment avalanches are registered. The information from satellites shows thermal anomalies. Mud flows come down off the slopes of the volcano. According to head of the Ust-Kamchatski district , the thawing of the snow on the warmed cupola of the volcano had caused a flood of the Bekesh river. The level of water has come close to the sole bridge linking the banks. If the bridge is washed down the Ust-Kamchatski district will be left without land communication between it and the Regional centre for 2-3 months. This, in turn, can become a serious obstacle to the preparation for the 2003 salmon-catching season.
