Pacaya volcano (Guatemala) activity update: deep-seated explosive activity

The volcano's activity has been comparably calm recently, characterized by strong degassing from the intra-crater cone that formed during the latest period (2015-16) of strombolian activity and has become impressively large, filling a good part of the crater now.
On a recent video, no ejections of lava fragments are visible, but rather near-continuous, pulsating emissions of steam and ash. These probably reflect an activity weaker than, but essentially similar to what we observed in Dec last year: spattering-type degassing ("bubbling") from the magma column inside the cone, generating near-continuous small strombolian explosions. The only real difference would be that this time the effusion rate is too low and activity too deep to eject incandescent lava spatter.


INSIVUMEH mentions a bluish gas plume rising up to 800 m from the Mackenney crater (to 3,300 m altitude) and no apparent explosive activity. On the other hand, internal seismic activity and the mentioned observation of spattering-type degassing, as well as a thermal signal from the volcano seen on satellite data suggest that the eruptive activity continues with little changes (just less visible).

Mild strombolian activity continues from the Mackenney crater. According to a recent report, this activity ejected glowing material to 75 m above the crater and weak incandescence could be observed from the crater at night. [more]

The activity at the volcano has started to increase during the past days. Explosion sounds and visible incandescence have become stronger. ... [more]

Mild activity continues at the intra-crater cone of the Mackenney crater. INSIVUMEH reports a steam and gas plume rising 600 m and glow from lava visible at night. [more]
Wednesday, Jan 13, 2016
The active intra-crater cone continues to grow (and slowly fill the crater). During clear nights, incandescence can be seen from the Mackenney crater. [more]
