Fuego (Guatemala) - Report for 21 October-27 October 2015 - NEW

GVP Eruption Reports - Wed, 10/28/2015 - 12:57am

INSIVUMEH reported that during 21-22 October explosions at Fuego generated ash plumes that rose 350-650 m above the crater. A lava flow advanced in the Santa Teresa (W) drainage. Seismicity increased during 25-26 October, and gas-and-ash plumes rose 1.2 km and drifted S and SW. Lava fountains rose as high as 200 m, feeding 850-m-long lava flows in the Santa Teresa and Trinidad (S) drainages. On 27 October lava fountains rose 300 m, and lava flows advanced as far as 1.5 km in the Santa Teresa, Trinidad, and Las Lajas (S) drainages. Strombolian explosions produced ash plumes that rose almost 1 km high.

Rinjani (Indonesia) - Report for 21 October-27 October 2015 - NEW

GVP Eruption Reports - Wed, 10/28/2015 - 12:57am

PVMBG reported that on 25 October at 1004 an eruption at Rinjani generated an ash plume that rose 200 m above the Barujari crater, inside the caldera. Ash fell on the flanks, especially to the SW. The report noted that no seismic nor surficial precursory events were detected. The Alert Level was raised to 2 (on a scale of 1-4). Based on satellite observations, the Darwin VAAC reported that on 26 and 28 October ash plumes rose to altitudes of 3-4 km (10,000-13,000 ft) a.s.l. and drifted 45-75 km SW and WSW.

Turrialba (Costa Rica) - Report for 21 October-27 October 2015 - NEW

GVP Eruption Reports - Wed, 10/28/2015 - 12:57am

OVSICORI-UNA reported that a small ash eruption at Turrialba began at 1153 on 23 October. An explosion at 1710 on 24 October produced an ash plume that rose 800 m above the crater and drifted SSW. Multiple explosive events occurred during 24-25 October; poor weather conditions sometimes prevented views of the activity. On 25 October 10-minute-long explosive events began at 0730 and 0927 and generated ash plumes that rose 1.5 km and 200 m, respectively; plumes drifted NW and W. Pyroclastic flows from collapsing ash columns were generated both times. Volcanologists conducting fieldwork on 26 October observed morphological changes at the S edge of the W crater and nearby areas due to the recent activity. They noted fresh light-colored ash and tephra deposits on the steep wall of the active crater. Three small explosions generated ash, steam, and gas emissions. Tephra was deposited as far as 400 m away in various directions from the crater.

Santa Maria (Guatemala) - Report for 21 October-27 October 2015

GVP Eruption Reports - Wed, 10/28/2015 - 12:57am

INSIVUMEH reported that on 21 October heavy rainfall in the area triggered steaming hot lahars which descended Santa María’s Nima I and San Isidro drainages. Both lahars carried blocks as large as 1.5 m in diameter; the Nimá I deposit was 18 m wide and 1.5 m deep. Explosions during 21-22 October generated ash plumes that rose 700 m above the crater and drifted SW, causing ashfall in El Rosario Palajunoj finca. Ash plumes from explosions drifted S and SE during 25-26 October; ashfall was reported in areas downwind.

Servicio Geológico Colombiano’s (SGC) Observatorio Vulcanológico y Sismológico de Manizales reported that during 20-26 October seismicity at Nevado del Ruiz was characterized by long-period earthquakes and short-duration volcanic tremor associated with gas-and-ash emissions. Earthquakes occurred at depths between 1.1 and 8.8 km. The largest event was recorded at 0953 on 21 October, a local M 2.3, near Arenas Crater at a depth of 3.4 km. Significant amounts of water vapor and gas rose from the crater during the week. A gas, steam, and ash plume rose 2 km on 22 October. The Alert Level remained at III (Yellow; "changes in the behavior of volcanic activity").
