Santiaguito volcano eruption with pyroclastic flows
Activity type : Peléenne
Morphology : dacitic dome complex.
Geographical location: 14 ° 44 ’33 “North Latitude, 91 ° 34′ 13” West Longitude.
Santiaguito Volcano continues its process of strong explosive activity. Again this morning, a second explosion in the last 24 hours has generated pyroclastic flows, from the edge of the crater of dome Caliente , down through the ravines to the east and west of the volcanic complex.
This activity is generated by the collapse of the eastern and western edge of the crater, raising a cloud of ash to 10,058 meters. (33,000 feet) (reported by a pilot) to the West, South-West , over a distance of 40 km, but the ash plume is still moving. With these fine ash, it is estimated that they can reach longer distances than previous eruptions and deposit on San Felipe Retalhuleu, El Nuevo Palmar, San Marcos and Loma Linda Palajunoj, Las Marias, Calguache, las fincas El Faro, Patzulin Monte Claro, El Patrocinio, Monte Bello and others in this area.
Santiaguito volcano, maintaining its high-level processes continue to generate such similar or violent events, which may generate large pyroclastic flows. Also note that on the volcanic zone, began the rainy season, which can cause moderate to strong lahars, because of the amount of volcanic material eruptions of last year and this year, mainly the afternoon and evening, in the rivers San Isidro, Cabello de Angel , Tambor, Nima I, tributaries of the river Samala.
Therefore, the INSIVUMEH recommends:
A CONRED, to maintain state warning it deems necessary and to take precautions for the populations affected by ash fall, and which cause contamination of drinking water, respiratory problems and eye problems .
At the Directorate General of Civil Aviation, to take precautions for air traffic, as this type of ash moves west directions, Southwest, Northwest at 4500 meters above sea level, with the potential to be transported over distances of 50 kilometers or more.
