Sulfur dioxide plume covers southern Enclosure, the Plain of Kaffirs, Le Tampon, and the drainage towards the coast.
 

The presence of summital VT earthquakes been studies of the Observatory. According to Nicolas Villeneuve (on Clicanoo), they could characterize a phase prior to going back to work, or things deeper not yet well mastered.
