Seismic recording from Pacaya on 5 Feb (INSIVUMEH)
Yesterday's seismic recording from Momotombo volcano (MOMN station, INETER)
Current seismic signal from San Miguel (VSM station, SNET)
Seismic signal from Tungurahua (RETU station, IG)
Tolbachik (Kamchatka): The eruption continues with little changes.
Photographer Olivier Grunewald who has been at the eruption site at the beginning of the year, with the French magazine Figaro, presents a selection of photos on youtube - a must-see:

Ambrym (Vanuatu): A strong SO2 plume is hovering over the island today. Good news for our guests going to visit Ambrym, it seems that the lava lakes continue to be active.
Iliamna (Cook Inlet (SW Alaska)): Seismicity has risen again at the volcano recently, earthquake-report mentioned. Events as large as M1.4 occurred along a (ring?) fracture located south of the volcano’s summit.
Colima (Western Mexico): Activity has been slowly increasing. Inside the summit crater, the lava dome has been growing slowly and producing numerous small explosions. Their number has recently increased from about 10 to 20 on average per day.
Popocatépetl (Central Mexico): A phase of increased activity has just started at Popocatépetl. Accompanied by strong tremor, a continuous ash and steam emission column is rising to 23,000 ft (7 km) altitude and drifting NW.
Santa María / Santiaguito (Guatemala): A slightly stronger than average explosion occurred earlier today, producing an ash plume rising more than 1 km above the dome and drifting SE.
Pacaya (Guatemala): 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.
The gas-ash vening also shows also up on the seismic station of PCG at intervals of 3-15 minutes.
Momotombo (Nicaragua): Some seismic unrest has been going on at the volcano. Local and volcanic earthquakes as well as what seem to be long-period events (corresponding to fluid movements) have been increased recently.
San Miguel (El Salvador): Seismic unrest (fluctuating, sometimes strong volcanic tremor and earthquakes) continue. Several hot spots are visible on the volcano's flanks, but most likely caused by fires.
Tungurahua (Ecuador): Eruptive activity consists in a constant steam and ash column rising about 1500 m above the crater and drifting SW. Individual explosions are sometimes heard. Seismicity continues to show an increasing trend.
