Roundup of Global Volcanic Activity

Klyuchevskoy | Central Kamchatka (Russia) | 56.056°N, 160.642°E | Elevation 4754 m

KVERT reported that a Strombolian eruption at Klyuchevskoy continued during 14-21 October. Gas-and-steam emissions with variable amounts of ash rose from the summit crater and from the cinder cone in the Apakhonchich drainage on the E flank. A lava flow traveled down the Apakhonchich drainage. Satellite images showed a large and bright daily thermal anomaly at the volcano, and ash plumes from explosions that rose to altitudes of 5-6 km (16,400-19,700 ft) a.s.l. and drifted 300 km NW, E, and SE during 14 and 18-19 October. The Aviation Color Code remained at Orange.

Sheveluch | Central Kamchatka (Russia) | 56.653°N, 161.36°E | Elevation 3283 m

KVERT reported that during 14-21 October lava-dome extrusion onto Sheveluch’s N flank was accompanied by strong fumarolic activity, dome incandescence, ash explosions, and hot avalanches. Satellite images showed a daily thermal anomaly over the dome. According to video and satellite data, explosions generated ash plumes that rose to altitudes of 6-7 km (19,700-23,000 ft) a.s.l. and drifted 210 km NW, E, and SE during 14-16, 18, and 20 October. The Aviation Color Code remained at Orange.

Turrialba | Costa Rica | 10.025°N, 83.767°W | Elevation 3340 m

OVSICORI-UNA reported that during 18-22 October continuous passive ash emissions rose from Turrialba as high as 1 km above the vent and drifted NE and W. The activity was accompanied by stable, low-to-moderate amplitude tremor with a few brief intervals of rest. Ash fell in Siquirres (30 ENE), Guacimo (23 km NNE), Guapiles (21 km N), and Moravia (27 km W). During 23-25 October emissions were discontinuous and ash content was low; plumes drifted NW and W. Ashfall was reported in San José (36 km WSW), Tibás (35 km WSW), Guadalupe (32 km WSW), Curridabat (32 km WSW), Tres Ríos (27 km SW), Moravia, San Pedro (32 km WSW), and various areas of the Valle Central.
