Volcano activity of July 5, 2012 – DR Congo, Canary Islands, Mexico, Colombia and Ecuador

This (almost) daily post intends to follow up the activity changes of volcanoes all over the world.
This post is written by geologist Richard Wilson who specializes in Volcano seismicity and Armand Vervaeck. Please feel free to tell us about new or changed activity if we haven’t written about it. -

July 5, 2012 volcano activity

A large eruption appears to have begun (and continues) at either Nyragongo or Nyamlagira (DR Congo) (due to lack of detail in satellite imagery) volcanoes around 01 July.  Modis SO2 data show a large plume eminating from that region beginning on 01 June.  Modis thermal imagery data are equivocal due to interference from convective activity which plagues the area.  This likely amplification of activity we reported on last month.

Seismicity is diminished, but continues beneath El Hierro (Canary Islands) during the past 24 hours.

A new volcano-tectonic earthquakes swarm has begun at Popocatepetl (Mexico).  The volcano continues to emit mostly water vapor, SO2, and other gases, occasionally admixed with a little ash. The video below is a nice example of what can be done with 5 hours of pictures.

Small earthquakes and tremor are also  ongoing at Galeras volcano (Colombia) (station ANGV).

A brief eruption occurred at Tungurahua (Ecuador) earlier today (station RETU).
