increased activity of the volcano PACAYA
Morphology: composite Stratovolcano
Geographical location: 14 ° 22 ’50 “N Latitude; 90 ° 36’00” W. Longitude
Height: 2552 m.
The diagram eruption of volcano Pacaya showed changes in the last hours, with an increase in RSAM measurements (Measuring the Magnitude of Earthquakes in real time). It has been observed increased activity in the crater Mackenney where it was possible to hear some rumblings sometimes accompanied by small explosions .It was also noted the increase in crater glow at night.
Seismic activity recorded by the PCG station is mainly associated with tremors (internal vibration) generated by the ascent of magma to the surface.
This activity will be increasing in the coming hours and produce lava flows and Strombolian explosions of greater magnitude.
Low expulsions with blue and white fumaroles degassing is observed, this plume has an approximate height of 100 meters (328ft) above the crater and spreads south.
Therefore the INSIVUMEH recommends:
A CONRED to review their emergency plans and to be aware of changes in the activity of the Pacaya volcano.
