Fuego Volcano 2014 /USGS Weekly Volcanic Activity Report

Fuego | Guatemala | 14.473°N, 90.88°W | Elevation 3763 m

In a special report, INSIVUMEH reported that on 7 January seismicity at Fuego increased. Explosions generated shock waves that vibrated structures more than 15 km away, and rumbling noises were audible 30 km away. Ash plumes rose 4.2 km above the crater and drifted 10 km SW. Lava flowed 500 m down the SW flank and produced avalanches that reached vegetated areas. During 9-10 January Vulcanian explosions generated shock waves detected within 10 km, ejected pulses of incandescent material 100 m high, and produced ash plumes that rose 300 m and drifted 10 km NE. Avalanches descended the Ceniza (SSW), Trinidad (S), and Taniluya (SW) drainages, and lava flows continued to descend the flanks. During 10-11 January explosions produced shock waves, and ash plumes that rose 650 m and drifted S, SW, and W. Crater incandescence was observed at night. During 12-13 January explosions caused shock waves that vibrated structures in Panimaché I and II (8 km SW), Morelia (9 km SW), Santa Sofía (12 km SW), Ceilán, La Rochela, and San Andrés Osuna. Ash plumes rose 350-650 m and drifted 10 km SW and W. Incandescent material was ejected 200 m above the crater and avalanches descended the Taniluya, Ceniza, Trinidad, Las Lajas (SE), and Honda (E) drainages. A 200-m-long lava flow traveled down the Trinidad drainage. Seismicity remained high on 13 January. Ashfall was reported in Panimaché, Morelia, and Sangre de Cristo (8 km WSW). A 500-m-long lava flow remained active in the Ceniza drainage. On 14 January explosions generated shock waves audible 8 km away, ejected incandescent material 150 m high, and produced ash plumes that rose 300-800 m and drifted 8 km W and SW. Avalanches again descended multiple flanks. Ash fell in Santa Sofía, Panimaché, Morelia, and Sangre de Cristo.

Pacaya Volcano January 2014

Pacaya | Guatemala | 14.381°N, 90.601°W | Elevation 2552 m

INSIVUMEH reported that during 9-10 January explosions at Pacaya ejected lapilli up to 70 m above the crater. White and blue fumarolic plumes drifted SE, and the seismographs recorded constant tremor. On 11 January Strombolian activity was observed, and new craters on the E, S, and W flanks produced lava flows as long as 1.5 km. Activity from the main crater increased; explosions ejected tephra 75 m high and gas plumes rose 200-600 m. CONRED reported evacuations from Villa Canales (14 km NW), El Chupadero (2-2.5 km S), and San Vicente Pacaya (5 km NW). INSIVUMEH noted that RSAM values decreased throughout the day. Activity further decreased on 12 January. Explosions ejected tephra 100 m above the crater and gas plumes rose 200-300 m. Lava effusion, Strombolian activity, and seismicity declined. During 12-13 January lava effusion remained low and lava flows reached 2.8-3 km long. Bluish-white gas plumes rose 300 m. During 13-14 January Strombolian activity ejected lapilli as high as 70 m, and blue and white plumes drifted S.

View of the Volcanoes Atitlan and San Pedro Tolimán Road to Quetzaltenango.
It is assumed that from this viewpoint you can see the world’s most beautiful lake, Lake Atitlan, but only managed to see the volcanoes that surround it.

Se supone que desde este mirador se puede ver el Lago mas Bello del Mundo -Lago de Atitlán- Pero solo logré ver los Volcanes que lo rodean.

March 5, 2013 volcano activity

INSIVUMEH reports small strombolian explsoins continue at the summit of Fuego volcano (Guatemala) today. Periodic jet-like roars are also reported coming from the vent. Occasional moderate-sized hot avalanches/pyroclastic flows affect Taniluya drainage at the volcano as well. One moderate explosion was reported this morning at Santiaguito Dome Complex (Santa Maria volcano). An ash plume associated with the burst rose to 3200 meters. Light ash fall from explosions and small hot avalanches/pyroclastic flows descending the Caliente dome dusted San Jose and la Quine villages today. Low level tremor and small volcanic earthquakes rumble within Pacaya volcano (station PCG). Recent MODIS satellite imagery shows multi-pixel “hotspots” associated with active lava flows at both Fuego and Santa Maria volcanoes.
