Strange Sounds | Dec 14, 207 | Enhanced volcanic activity around the world: AGUNG (Indonesia) , CLEVELAND (Alaska), SAKURAJIMA (Japan), NEVADO DEL HUILA (Colombia), SANTIAGUITO (Guatemala) |

Many volcanoes are currently puffing large ash plumes around the world. Here a compilation of active volcanoes erupting worldwide.

Agung volcano, Indonesia

Volcanic activity continues at Agung volcano on the island of Bali with eruptions as well as gray, white, thick, medium pressure ash puffs reaching a height of about 500 to 2000 m above the summit and slope westward and eastward. At night, the glow of the incandescent lava in the crater of the volcano is observed.

Communities around G. Agung and mountaineers / visitors / tourists must not climb, climb or do any activity in the danger zone around the G. Agung crater area and in all areas within 8 km from the crater.

Cleveland volcano, Alaska:

An explosion was detected at Cleveland Volcano in seismic and infrasound data this morning 04:20 AKST (13:20 UTC). The explosion produced an eruption cloud that was observed in satellite data to an altitude of up to 20,000 ft asl and moving to the east.

AVO is raising the color code for Cleveland to Aviation Color Code ORANGE and Alert Level WATCH. No new activity has been observed at Cleveland Volcano since the explosion at 04:20 AKST (13:20 UTC) this morning.
Sakurajima volcano, Japan

An explosion at Showa Crater (at Aira Caldera’s Sakurajima volcano) occurred at 18:45 on 4 December and generated an ash plume that rose 1.4 km above the crater rim.

Very small events occurred at Minamidake Crater during 7 and 9-10 December, and at Showa Crater on 10 December. The Alert Level remained at 3 (on a 5-level scale).
Nevado del Huila, Colombia

The level of activity of the volcano continues at the level of activity yellow or (III): changes in the behavior of volcanic activity.

Between 5 and 11 December 2017, the Colombian Geological Service – Volcanological Observatory of Popayán reports 209 seismic events were recorded, 153 of which were related to rock fracturing processes (type VT) and 56 to fluid dynamics in volcanic canals. Of these, 52 were classified as long-period type events (LP type), three (3) as low-amplitude Tremor pulses (TR type) and one (1) hybrid event, which were associated with as in the transit of fluids (type HB). Webcams in Tafxnú, Maravillas and La Palma, recorded degassing of the volcanic system, sending white columns of ash and gas at the top of the volcano. No variations of soil deformation, magnetic fields and infrasonic waves have been recorded. Therefore, the volcano shows a stable behavior.
Santiaguito, Guatemala

Active degassing is observed. Ash and gas plume reach 9,515 ft and disperses in the southwest direction. Seismic station have recorded weak explosions at night and early morning hours, generating gray columns at an approximate height of 3,200 meters (10,499 feet), moving southwest.

Be prepared in case a volcano erupts around where you live!
