Review of volcanic activity from 16 to 22 May 2012

During this period of seismic events occurred in 12 volcanoes, signs of a new volcanic activity appeared in two volcanoes:
Fuego (3763 m, Guatemala, 14,473 ° N, 90,880 ° W)
May 19 seismic activity of the volcano has increased significantly. Explosions could be heard above the Fuego at intervals of 5-10 minutes. The western and eastern slopes of the lava flowed 600 meter and kilometer length, reaching the bottom. The red-hot ash and tephra erupted continuously from the crater. Danger code was raised to "orange", because of the use of flow tephra the motorway in the vicinity of the volcano has been restricted. 13 people had to be evacuated. Later came the activity subsided.
MARAPI (2891 m, about. Sumatra, Indonesia, 0.381 ° S, 100.473 ° E)
May 18 eruption at Marapi lasted about 10 minutes, then a column of ash up to 600 meters above sea level. In four levels of the volcano hazard estimate by 2 points.
This stratovulkanichesky kopmpleks, located in the valley of Bukittinggi is the most active on the island. Sumatra. In the north-eastern and south-western part of the broad peaks within a small 1.4-km caldera has combined several craters. From the late 18th century, the volcano eruptions were more than 50 middle and lower average magnitude. Lava never flowed outside the craters.

Volcanoes of the continuing activity:

BATU-TARA (784 m, about. Komba, Indonesia, 7.792 ° S, 123.579 ° E)

According to data from the satellite, 18, and 20-21 May sang emissions rose above the volcano to a height of 2,4-3 km above sea level and the air flow were attributed to 27-55 km to the north-north-west.
CLEVELAND (1730 m, about. Chuginadak, Alaska, 52,825 ° N, 169,944 ° W)
May 16-22 at the Cleveland does not have a particular change; power emission of ash and other seismic attributes has not increased. Danger code is "orange."
DUKONO (1335 m, about. Halmahera, Indonesia, 1.68 ° N, 127.88 ° E)
May 18 ash cloud rose to a height of 3 km above the volcano and the wind was referred to 55 km to the east.
KARYMSKY (1536 m, East Kamchatka Peninsula, Russia, 54,05 ° N, 159,45 ° E)
Volcano continues to show signs of moderate-intensity activity. 10 and 14 May ash rose over the top at a height of 1.8 km above the volcano. May 10-13, the volcano satellite thermal anomaly was detected. Danger code is "orange."
Kilauea (1222 m, Hawaii, USA, 19,421 ° N, 155,287 ° W)
May 16-22, there was always activity in the crater lake lavogogo Gamalema-mind-at the level of which rose and fell. Several times the contents splashed on the slopes of Kilauea. Gas clouds over the volcano contained a large amount of ash. Small lake of lava on the crater of Pu-u-oh constantly empty out the hot spray out. May 19 one of the edges of the lake broke and capacity of lava took more space. With one of the valves on the southern slope of the volcano to the bottom began to emerge a small lava flow stopped at 750 m from the sea.
Popocatepetl (5426 m, Mexico, 19,023 ° N, 98,622 ° W)
Every day, in spite of the poor visibility over the top of the volcano recorded numerous clouds of gas and ash, with a height of 1.5 km above sea level. Heated rock fragments were ejected from the crater to a distance of 800 m level of seismic activity is extremely high. In volcano "yellow" hazard code of the third stage.
Sakurajima (1117 m, about. Kyushu, Japan, 31.585 ° N, 130.657 ° E)
16-20 and 22 May at the volcano constantly blasts, the ash cloud reached the 1,8-3,7 km, which was complicated by the movement of air transport. Especially the involvement of activity at Showa crater, repeatedly throws portions tephra on distance 1.8 km from the summit. At night on the crater glow noted breed. The Crater Minami activity was less intense, just a few eruptions and pyroclastic flows on the 300-meter distance.
SANTA MARIA (3772 m, Guatemala, 14,756 ° N, 91,552 ° W)
May 21 on the slopes of the volcano down lahars of fallen trees and debris of lava 40-centimeter-wide. May 22 because of another izverzheniynad Caliente crater rose portion ash to a height of 900 m loss ash noted within 12-15 km.
SHIVELUCH (3283 m, the center of the Kamchatka Peninsula, Russia, 56.653 ° N, 161.360 ° E)
May 11-18 explosive activity at the volcano continued. From active crater continuously poured huge lava flow, fumaroles are also constantly working. Lava dome considerably hot. May 10-12 and May 15-16, it was observed thermal anomaly. May 12 ash cloud rose to 8 km above sea level and 20 May at the height of 9.1 km.
Tungurahua (5023 m, Ecuador, 1,467 ° S, 78,442 ° W)
May 16-22, the conditions for monitoring the volcano almost was not. On the western slope of the Tungurahua A few lahars, were small clouds of gas and ash para.soobschaetsya of loss within 8 — km to the south and southwest of the volcano. May 22 Volcano began publishing characteristic growl, still throw ashes.
