Reventador volcano (Ecuador): activity remains high, frequent small to moderate explosions
Mon, 8 Aug 2016, 16:52 16:52 PM | BY: T
At the moment, this is Ecuador's most active volcano. According to the Istituto Geofisico (IGEPN), its activity is "high". A lava dome continues to grow at the summit crater.

Strong degassing generates a plume of steam and gas rising 500-1000 m and frequent small to moderate explosions produce ash plumes that rise to similar heights. In total, IGPEN counted 38 explosions during an 24 hour interval, based on seismic and webcam observations. Most of the time, these can not be observed directly due to frequent cloud cover.
Based on satellite observations, a stronger ash emission was reported by VAAC Washington this afternoon (at 14:18 UTC) with an ash plume reaching 19,000 ft (6.5 km) altitude, or approx. 2 km height above the crater.

Reventador volcano (Ecuador) - Smithsonian / USGS Weekly Volcanic Activity Report for 3 August-9 August 2016 (Continuing Activity)
During 3-9 August IG reported a high level of seismic activity including explosions, long-period earthquakes, harmonic tremor, and signals indicating emissions at Reventador; cloud cover sometimes prevented visual observations. Incandescent blocks rolled as far as 1 km down the flanks. Gas, water vapor, and ash plumes rose from the crater during 3-4 and 6-7 August; the plumes rose as high as 1 km on 6 August. ... Read all

Reventador volcano (Ecuador) - Smithsonian / USGS Weekly Volcanic Activity Report for 22 June-28 June 2016 (Continuing Activity)
On 24 June IG stated that surficial activity at Reventador had remained high during recent months. While conducting routine maintenance work of the monitoring network on 8 June, IG staff noted continuous gas-and-water-vapor emissions rising 800 m above the crater and drifting NW. Explosions produced sounds similar to gunshots and generated ash plumes that rose 2 km. ... Read all
