Review of volcanic activity from 23 to 29 May 2012 It is interesting
During this period of seismic events occurred in 16 volcanoes, signs of a new volcanic activity appeared in five volcanoes:
Fuego (3763 m, Guatemala, 14,473 ° N, 90,880 ° W)
May 22-23, after the explosions at the volcano ash cloud rose to a height of 700 m above the crater and flew off to the west and southwest. From the south-east side of the Fuego A few showers with rubble. May 25 in the crater appeared fresh lava. Ash rose even higher, to 2 km, and dropped in populated areas within 8 km. Later came down from a volcano pyroclastic flow. May 26-29, ash emissions were repeated, the new lava flow down to 200-300 m down with new avalanches. May 28-29 at the volcano glow noted rock at a height of 100 m
GALUNGUNG (2168 m, west of. Java, Indonesia, 7,25 ° S, 108,058 ° E)
Activity at the volcano increased gradually, starting in mid-February. However, from the end of April the temperature, pH-balance of water in the lakes around the crater and external surveillance forced seismologists reduce risk code from the second to the first level (on the four-level scale). Forest-covered cone volcano caldera is truncated in a horseshoe shape, whose age is not less than 4200 years. Despite infrequent eruptions, they bring a lot of trouble and destruction. Thus, in 1822, pyroclastic flows and lahars have caused the deaths of more than 4 thousand people. Large losses suffered population of the island during the peak activity Galungunga in 1982-1983.
Nevado del Ruiz (5321 m, Colombia, 4,895 ° N, 75,322 ° W)
May 29 seismic activity of the volcano has increased significantly. Began to rise above the crater new cloud of ash to a height of 1 km. Danger code was raised to "orange." On the loss of ash reported localities within a radius of 33 to 78 km. Satellites detected the cloud of sulfur dioxide over Colombian volcano, which was confirmed by the testimony of local residents who feel the characteristic smell.
SIRUNG (862 m, about. Pantar, Indonesia, 8,508 ° S, 124,13 ° E)
May 13-18 scattered white clouds of smoke rose to 10-50 m above the volcano. By May 23 the recently increased activity decreased slightly, which caused a decrease in the code risk level 2 on a four-point scale. Sirung belongs to the 14-km-long line of volcanic centers forming Pantar Island. Gore, mainly consisting of solidified basaltic lava truncated caldera width of 2 km. In the 20th century it was the site of several phreatic eruptions.
SOPUTAN, (1784 m, about. Sulawesi, Indonesia, 1,108 ° N, 124,73 ° E)
May 21-27, at 5-150 m above the top of the volcano there were white clouds of smoke. May 25 earthquake activity has increased significantly, so the danger level was raised to a value of 3. Soputan located on the southern edge of the Quaternary caldera Tondano. Virtually all of the crater eruptions occur Esput and the valve on the northeast flank of the volcano, formed in 1906. In the period up to 1924 from there flowed the main mass of lava.
Volcanoes of the continuing activity:
Bagan (1750m, about. Buganvill, Melanesia, 6,140 ° S, 155,195 ° E)
With the help of satellite imagery on the eastern slope of the volcano was detected lava flow. But does not apply to the current phase of activity. The volcano is located in a remote part of the island and is one of the youngest and most active volcanoes in Melanesia. By its nature, it is a symmetrical cone of lava origin, formed over 300 years and continues to evolve. Normally, emissions of lava at Bagan are no explosions, just sometimes accompany pyroclastic flows.
CLEVELAND (1730 m, about. Chuginadak, Alaska, 52,825 ° N, 169,944 ° W)
May 23-29, new emission of ash and other signs of activity at the volcano was observed. Danger code is "orange."
DUKONO (1335 m, about. Halmahera, Indonesia, 1,68 ° N, 127,88 ° E)
May 25 ash above the volcano rose to 4.5-meter height. A couple of days emissions repeated.
KARYMSKY (1536 m, East Kamchatka Peninsula, Russia, 54,05 ° N, 159,45 ° E)
May 18-25 volcanic activity remained at an average level, ash rose to a height of 2.2 km, and May 27 at 3 km. 17-18, 20, 22 and 24, the volcano was observed thermal anomaly. Danger code is "orange."
Kilauea (1222 m, Hawaii, USA, 19,421 ° N, 155,287 ° W)
May 23-29 at the volcano saw the rise and fall of the level of lava in the crater Gamalema-mind-y, which is why some sites edge of the crater collapsed. Cloud of gas and ash portions periodically erupted from the volcano. May 23 is a small stream of lava down the slope of a small crater on the south side. Closer to May 28 is no longer boiling lava and spitting from the crater Pu-u-Oh.
Popocatepetl (5426 m, Mexico, 19,023 ° N, 98,622 ° W)
May 23-29, at 2 km reappeared clouds of ash and gas. Ashes fell within 10-25 km. May 23-26, hot rock fragments periodically breaking out of the crater. Danger code volcano remains "yellow" in step 3.
Sakurajima (1117 m, about. Kyushu, Japan, 31,585 ° N, 130,657 ° E)
May 21-25 at the volcano recorded eight explosive episodes on Showa crater and a little push to Minami-dake. 23-24 and 26-28 May explosions raised portion of the ash to a height of 1,8-4,6 km above sea level.
Sangay (5230 m, Ecuador, 2,002 ° S, 78,341 ° W)
On May 28, the volcano erupted, after which the ashes rose to 6.1 km above sea level. However, the images from space availability ash column was not confirmed.
SANTA MARIA (3772 m, Guatemala, 14,756 ° N, 91,552 ° W)
22-23 and May 28-29 at the lava dome in the Caliente complex Santiaguito been several eruptions, accompanied by emission of ash to a height of 400-900 m 26-27 May lava flows caused an avalanche of debris on the west side of Santa Maria. May 29 at the southern foot of the lahars down, seized the tree branches and stones with a diameter of 1-1.5 meters.
SHIVELUCH (3283 m, the center of the Kamchatka Peninsula, Russia, 56,653 ° N, 161,360 ° E)
May 18-25 explosive activity at the volcano did not wane. Daily thermal anomaly observed. Active crater continued to produce lava flows, fumaroles continued their activities, as well as the heating of the lava dome. Ash was observed at an altitude of 8.9 km above sea level. Aviation Hazard Code is "orange."
Tungurahua (5023 m, Ecuador, 1,467 ° S, 78,442 ° W)
May 23-24 from the volcano in all directions echoed gas and ash that fell within 8 kilometers to the south-east and 30 km to the south. May 25 was a new eruption, accompanied by characteristic sounds of rustling and another portion of the ash at an altitude of 2.5 km. Later, clouds hid the volcano observation.
