Thursday, May 16, 2013
Strombolian activity has returned or increased and is now ejecting incandescent material to heights of 100 m. Seismic data seem currently not available from INSIVUMEH's website.
Tuesday, May 14, 2013
Activity seems to have decreased. INSIVUMEH no longer reports and strombolian activity visible or audible.
Monday, May 06, 2013
Current seismic recording at Pacaya (PCG station, INSIVUMEH)
Current seismic recording at Pacaya (PCG station, INSIVUMEH)
Weak strombolian activity probably continues. It can not always be observed, but only heard and shows on the seismic recording.
Tuesday, Apr 30, 2013
Small strombolian activity continues from the Mackenney crater.
Saturday, Apr 27, 2013
Current seismogram from Pacaya  (PCG station, INSIVUMEH)
Current seismogram from Pacaya (PCG station, INSIVUMEH)
Weak strombolian activity from the Mackenney crater, well visible at night, continues and has been showing a gradual increase over the past days. This is also evident from the seismic recording. Some explosions can be heard in up to 3 km distance.
Monday, Apr 22, 2013
Weak strombolian activity continues from Mackenney crater, accompanied by visible incandescence at night.
Saturday, Apr 20, 2013
After a few days with no or very little activity, incandescence and weak strombolian activity have resumed at the Mackenney crater.
Sunday, Apr 14, 2013
INSIVUMEH's latest bulletin confirms that a small lava lake is present in the Mackenney crater at a depth of 40 meters and generating mostly small strombolian explosions that eject material to the NW flank. ...more
Wednesday, Apr 10, 2013
Strombolian activity continues gradually to increase, and tephra is being thrown to about 25 m above the crater rim. Inside the Mackenney crater, a small lava lake has formed at the vent at a depth of 40 m, INSIVUMEH reports.

Current seismogram from Pacaya  (PCG station, INSIVUMEH)
Current seismogram from Pacaya (PCG station, INSIVUMEH)
Weak strombolian activity continues. The seismic shows a mix of surface events (explosions) and small earthquakes ad weak tremor pulses related to fluid movements inside the volcano.
Saturday, Apr 06, 2013
INSIVUMEH reports no changes during the last week. Mild strombolian activity continues, and is visible especially at night.
Thursday, Apr 04, 2013
Weak strombolian eruptions continue to be observed from Mackenney crater.
Tuesday, Apr 02, 2013
Strombolian activity has continued and seems to be becoming slowly stronger. Incandescent material can now be seen ejected at night and lands mainly on the western flank of Mackenney crater, where INSIVUMEH advises tourists not to go.
Sunday, Mar 31, 2013
Weak strombolian activity continues, accompanied by white-bluish degassing (SO2). So far, no new lava flow has appeared.
Wednesday, Mar 27, 2013
Weak explosions producing small plumes of steam and some ash and degassing were reported this morning.

This morning's seismogram from Pacaya (PCG station, INSIVUMEH)
This morning's seismogram from Pacaya (PCG station, INSIVUMEH)
The volcano continues to wake up progressively and "shows symptoms typical of generating new explosions and opening a new effusive vent for a lava flow" (INSIVUMEH) in the near future. ...more
Tuesday, Mar 19, 2013
Since last night, Pacaya volcano has been showing small strombolian activity, INSIVUMEH reports. The activity is from Mackenney crater and consists in weak explosions that throw incandescent bombs to up to 15 m above the crater. ...more

Current seismogram from Pacaya  (PCG station, INSIVUMEH)
Current seismogram from Pacaya (PCG station, INSIVUMEH)
Weak gas and ash emissions continue. The seismic signal shows small superficial explosion signals and pulses of tremor lasting up to about 30 minutes.

Current seismogram from Pacaya  (PCG station, INSIVUMEH)
Current seismogram from Pacaya (PCG station, INSIVUMEH)
The volcano continues to wake up. Small gas and ash emissions were observed from the crater yesterday. The seismic signal shows volcanic tremor and volcanic quakes related to internal fluid movements and the degassing/ash venting at the surface.
Thursday, Mar 14, 2013
INSIVUMEH reports continuing steaming/degassing and weak ash venting. Bluish gas and seismic activity suggest that magma is near the surface.
Wednesday, Mar 13, 2013
Occasional weak gas and ash emissions have been reported by INSIVUMEH who believes that a return to magmatic, likely strombolian activity from the Mackenney crater is a probable scenario for the near future (weeks).
Tuesday, Mar 12, 2013
No new explosive activity or other surface activity except degassing / steaming has been observed over the past days.

Seismic recording from Pacaya on 5 Feb (INSIVUMEH)
Seismic recording from Pacaya on 5 Feb (INSIVUMEH)
The eruptive behavior of Pacaya has changed once more on 5 Feb, INSIVEUMEH reported. Constant gas emissions with weak brownish ash were observed from Mackenney crater, and Guatemalan scientists believe that this is a sign that the conduit continues to be cleared and could produce more regular, magmatic activity, in the form of strombolian explosions, in the near future. ...more
