Pacaya volcano (Guatemala): continuing lava flows, Mackenney crater collapse

MODIS hot spot data (past 2 days) for Pacaya volcano (ModVolc, Univ. Hawaii)
While explosive activity seems to have ceased, lava effusion from the southern fissure vent at the base of the Mackenney cone continues and feeds an active flow field that expands up to 3.6 km from the vent.

Slowly advancing lava flow fronts continue to burn vegetation and have cut, as in 2010, the dirt road between the villages of El Rodeo and Pocitos.
The vent on the NW flank that fed the second large flow during the recent paroxysm is no longer active. Continuous tremor and bluish degassing from the summit accompany this process. According to the latest information of CONRED, the crater floor of the Mackenney cone has collapsed into a deep pit and the active cone at the vent that had been built over the past year has vanished.

The lava flow from the southern fissure vent at the base of Mackenney crater remains active, and weak strombolian activity occurs at the summit vent. [mehr]

INSIVUMEH reports weak strombolian activity at the volcano's summit crater. Continuous tremor suggests that some lava effusion from the southern fissure still continues. [mehr]

The volcano continues to effuse a weakly alimented lava flow from the southern fissure and has mild strombolian activity at the summit crater, with explosions occurring about every 2 minutes and ejections reaching 25-70 m above the crater. [mehr]

Activity continues to decrease back to normal levels. Apart from weak activity left at the southern fissure, the lava flow emission has ceased and the flows are now cooling. Strombolian activity at the summit vent decreased as well back to mild levels with ejections rarely surpassing 50 m. ... [mehr]

According to INSIVUMEH, the eruption has considerably slowed down since last evening around 19:15 (local time), although weather prevented detailed observations. Activity at the summit decreased to moderate strombolian explosions with ejections reaching 100 m height and degassing. ... [mehr]
