Pacaya Volcano

Weak degassing at a height of 150 meters above the crater dispersing in a northerly direction. The seismic station registers internal tremor associated with degassing and constant strombolian explosions, these raise material at an approximate height of 5 to 15 meters above the crater. During the night and early morning incandescence was observed in the Mackenney crater and two lava flows on the north west slopes of the of the volcano, with lengths of 50 m. Weak avalanches in the front of lava flows

Fuego Volcano

Weak degassing of white color at a low height, dispersing in east and northeast direction. There are reports of 8 to 10 explosions per hour, with weak and moderate characteristics, column of ash at an approximate height of 4,200 meters (13,779 feet) moving eastward and northeast. Explosions are accompanied by weak and moderate rumblings, weak and moderate shock waves that causes vibration in roofs and windows of houses near the volcano. Weak sounds like a locomotive train with one minute lapses. At night and early morning incandescence was observed in the crater at an approximate height of 200 meters above the crater, causing weak and moderate avalanches around the rim of the crater, some reach the vegetation towards the ravines: Seca, Taniluyá, Ceniza, Trinidad, Las Lajas and Honda. Fall of ash on the east and northeast flank, with the possibility of slight ash fall in Alotenango.

Santiaguito Volcano

Weak white degassing at an approximate height of 3,000 masl (9,842 feet) dispersing in the southwest direction. Weak explosions are registered, generating column of ash to an approximate height of 3,200 meters (10,499 feet) moving to the southwest, ash falling in the volcanic perimeter. Weak and moderate avalanches to the east of the dome.
