Typical eruption style:
Mildly explosive and effusive (Strombolian activity, lava fountaining, lava flows from the summit crater). Near continuously active the least during the past centuries.

The volcano remains quiet. INSIVUMEH reports only a continuous degassing plume reaching about 50 m above the crater.
Friday, Apr 18, 2014
INSIVUMEH only reports steaming and internal tremor, but no visible eruptive activity from the Mackenney crater at the moment.

Current seismic signal from Pacaya (PCG station, INSIVUMEH)
Current seismic signal from Pacaya (PCG station, INSIVUMEH)
Weak sporadic explosions have resumed at the Mackenney crater. Fine ash plume were observed rising to 2,6 km altitude and drifting approx. 1 km to the S and SW. The seismic signal shows continuous tremor and weak explosion signals.
Monday, Mar 10, 2014
According to INSIVUMEH, lava continues to flow from the vent (on the western base of the cone?), but is mostly inside small lava tubes. Strombolian activity at the summit vent seems to have decreased or ceased.

While lava flow effusions probably has stopped, weak and sometimes moderate strombolian explosions continue at the summit vent, producing small ash plumes rising 100-150 m.

This morning's seismic signal from Pacaya (PCG station, INSIVUMEH)
This morning's seismic signal from Pacaya (PCG station, INSIVUMEH)
Eruptive activity continues at reduced intensity as the seismic signal indicates. As of yesterday, INSIVUMEH reported still active flows from the vent at the western base of the Mackenney cone. Their length was between 1300-1600 m and they reached the southern base of the cone. Weak explosions were observed at the summit vent.

The latest eruptive phase of the volcano continues at decreased strength. The second paroxysm of Pacaya this year, only about 6 weeks after the previous one in January, started yesterday morning with lava fountains, associated ash emissions, as well as a new lava flow that quickly reached about 2 km length. ...more [read all]

Seismic signal from Pacaya today (PCG station, INSIVUMEH)
Seismic signal from Pacaya today (PCG station, INSIVUMEH)
A new phase of increased activity at the volcano began today. Strombolian explosions became more intense, ejecting incandescent bombs to approx. 200 m above the crater, and since this morning, a new lava flow started to descend from the summit on the western flank. The activity surge is reflected by a strong, gradual increase of tremor.
Mild strombolian eruptions occur at intervals of 5-10 minutes from the Mackenney crater.
Tuesday, Feb 25, 2014
Mild strombolian activity continues at the Mackenney crater. INSIVUMEH reports ejections of fine-grained tephra (ash) to 100-150 m above the crater.
