Monday, March 6, 2017, SUMMARY OF THE ACTIVITY OF THE VOLCANO

The volcano maintains its high activity. Yesterday afternoon an emission of steam and ash heading westward, which reached 1000 meters above the crater, was observed.

 

TECHNICAL AND OBSERVATIONS ANNEX
Seismicity: From 11h00 (TL) yesterday until 11h00 (TL) today, 3 episodes of tremor harmonic (TRA), 2 episodes of tremor of emission (TRE), 25 events long period (LP) and 35 explosions EXP) were recorded.
Emission and ash observations: Yesterday afternoon, the volcano was discovered and a steam and ash emission was observed in a westerly direction, with a height of 1000 meters above the crater.
Rains and lahars: Rains in the area that did not generate lahars were recorded.

California Volcanoes , United States :

Current Volcano Alert Level: all NORMAL
Current Aviation Color Code: all GREEN

Activity Update:
All volcanoes monitored by CalVO using telemetered, real-time sensor networks exhibit normal levels of background seismicity and deformation. Volcanoes monitored include Mount Shasta, Medicine Lake Volcano, Clear Lake Volcanic Field, Lassen Volcanic Center, Long Valley Volcanic Region, Coso Volcanic Field, Ubehebe Craters, and Salton Buttes.
Observations for February 1, 2017 (0000h PST) through February 28, 2017 (2359h PDT):
Mt Shasta: Two earthquakes at or above M1.0 were detected, with the largest registering M2.50.
Medicine Lake: No earthquakes at or above M1.0 were detected.
Lassen Volcanic Center: No earthquakes at or above M1.0 were detected.
Clear Lake Volcanic Field: Two earthquakes at or above M1.0 were detected, with the largest registering M1.42. [Note: The typical high level of seismicity was observed under the Geysers steam field located at the western margin of CLVF. The largest event was M4.16].

 

Salton Buttes

 

Long Valley Volcanic Region: In Long Valley Caldera, 14 earthquakes of M1.0 or greater were detected, with the largest event registering M2.34. One earthquake at or above M1.0 was detected in the Mono Craters region (M2.09). Three earthquakes at or above M1.0 were detected under Mammoth Mountain, with the largest registering M1.30. [Note: The typical high level of seismicity was observed south of the caldera in the Sierra Nevada range. The largest event registered M2.28].
Ubehebe Craters: No earthquakes at or above M1.0 were detected.
Salton Buttes: Eight earthquakes of M1.0 or greater were detected, with the largest registering M1.59.
Coso Volcanic Field: The typical high level of seismicity was observed, with 14 earthquakes M1.0 or greater. The largest registered M1.70.

The U.S. Geological Survey will continue to monitor these volcanoes closely and will issue additional updates and changes in alert level as warranted.

Fuego , Guatemala :

Activity type: Vulcanian
Morphology: Stratovolcan composite
Geographical location: 14 ° 28 ’54 ˝ Latitude N; 90 ° 52 ’54 « Longitude O
Altitude: 3,763m
Weather conditions: Clear
Wind: North 5 km / h
Precipitation: 0.0 mm.

Activity:
Degassing of low white fumarole at a low height which is scattered towards the southwest. There were four explosions, 2 low 1 moderate and 1 main column of gray ash that was emitted at a height of 4,300 to 4,800 meters (14,105 to 15,750 feet) which spread over 12-15 km to the west And to the south-west. 3 moderate rumblings and 1 low that generated low shock wave were heard, incandescent pulses at 75-100 m above the crater generated moderate avalanches in the gullies of Santa Teresa, Taniluya, Ceniza and Trinidad.
