Fuego (Guatemala) - Report for 11 March-17 March 2015 - NEW

GVP Eruption Reports - Tue, 03/17/2015 - 11:45pm

INSIVUMEH reported that during 10-11 March the magnitude and number of explosions at Fuego increased, producing ash plumes that rose 650-950 m above the crater and drifted 12 km W, NW, and N. Shock waves from explosions were detected in nearby areas including Panimache I and II (8 km SW), Morelia (9 km SW), Sangre de Cristo (8 km WSW), and San Pedro Yepocapa (8 km NW). During 12-13 March explosions generated ash plumes that rose 800 m and drifted 10-12 km S and SW. Incandescent tephra was ejected 100 m high. During 15-16 March ash plumes from explosions rose 550-950 m and drifted 10-12 km WSW; shock waves were reported and ash fell in Panimache, Morelia, and Santa Sofía (12 km SW).

Turrialba (Costa Rica) - Report for 11 March-17 March 2015 - NEW

GVP Eruption Reports - Tue, 03/17/2015 - 11:45pm

Based on webcam views, weather models, and OVSICORI-UNA updates, the Washington VAAC reported that on 8 March diffuse ash emissions rose from Turrialba's West Crater and seismicity increased. OVSICORI-UNA reported an ash emission at 0100 on 11 March. Another ash emission occurred at 1050 on 12 March. Almost continuous ash emissions were observed in the afternoon and were punctuated by two noticeable explosions at 1338 and 1450. Ash plumes rose as high as 2 km above the crater and drifted NW. Ashfall occurred in the Central Valley and in the capital of San Jose (30 km WSW), and caused the closure of the Juan Santamaria International Airport, 48 km W, which reopened during the evening on 13 March. The local Tobias Bolanos airport (40 km WSW) closed intermittently. On 13 March two short explosions occurred at 1045 and 1100, and then a third occurred at 2100. According to the VAAC, ash plumes that day drifted 45 km NE at an altitude of 9.1 km (30,000) a.s.l. and drifted over 35 km W at an altitude of 6.1 km (20,000 ft) a.s.l.

Ubinas (Peru) - Report for 11 March-17 March 2015 - NEW

GVP Eruption Reports - Tue, 03/17/2015 - 11:45pm

Instituto Geofísico del Perú (IGP) Observatorio Volcanológico del Sur (OVS) reported that during 10 February-17 March seismicity at Ubinas was generally low, although a hybrid event was detected on 11 March. Two main sources of seismicity were located 1 km W of the crater at depths of 1-3 km and 2 km NW at depths of 1-5 km. Water-vapor emissions rose as high as 1.5 km above the crater. Sporadic ash emissions were observed on 17 March.

Colima (Mexico) - Report for 11 March-17 March 2015

GVP Eruption Reports - Tue, 03/17/2015 - 11:45pm

Based on satellite images, Mexico City MWO, Colima Tower notices, and a webcam, the Washington VAAC reported ash plumes from Colima during 11-13 March. On 12 March an ash cloud observed in satellite images was located between 40 and 90 km ENE. Additional emissions produced ash plumes that drifted 50-90 km ENE. Later that day ash plumes rose to altitudes of 6.1-6.7 km (20,000-22,000 ft) a.s.l. and drifted E, ESE, and SE. On 13 March an ash plume rose to an altitude below 4.9 km (16,000 ft) a.s.l. and drifted E. Thermal anomalies were detected during 12-13 March.

Klyuchevskoy (Russia) - Report for 11 March-17 March 2015

GVP Eruption Reports - Tue, 03/17/2015 - 11:45pm

After a quiet period of 24 hours at Klyuchevskoy, volcanic-tremor magnitude significantly increased at 0500 on 10 March prompting KVERT to raise the Aviation Color Code to Orange. Video images showed moderate gas-and-steam activity while satellite images detected a gas-and-steam plume with small amounts of ash drifting about 92 km ESE at an altitude of 5 km (16,400 ft) a.s.l. During 10-11 March a weak thermal anomaly over the summit was detected.

Manam (Papua New Guinea) - Report for 11 March-17 March 2015

GVP Eruption Reports - Tue, 03/17/2015 - 11:45pm

RVO reported that activity at both Manam's Southern Crater and Main Crater was low during 1-18 March although inclement weather made crater observations difficult; no noises were reported. Seismicity had slowly and erratically increased since 28 February, peaked on 13 March and remained at that level through 15 March, and then increased again through 18 March. The seismicity was characterized by small-to-moderate, sub-continuous, and continuous volcanic tremor. Discrete low-frequency earthquakes were also recorded.
