Roundup of Global Volcanic Activity

Reventador (Ecuador): A new phase of intense activity with possible lava fountains and new lava flows began at the volcano yesterday. Over the past weeks, the volcano had been in a state of mild intermittent strombolian explosions, but experienced a rapid increase in activity yesterday after around 15:00 local time. Infrared webcam images (collected by Culture Volcan) suggest that a phase of lava fountaining or much stronger strombolian explosions took place. The apparent surge in lava emission also seems to have produced a new lava flow about 3-400 m long. This increase in activity is clearly visible in the corresponding seismic signal and likely continues at the moment.

Tungurahua (Ecuador): While surface activity has been fluctuating at generally low levels with only sporadic small steam and ash emissions, IGPEN reports that there are signs that suggest that a new batch of magma might be on its way to the surface. During the past days, there had only been sporadic steam emissions of up to 500 m height and 3 small ash explosions on 22 April with no explosion sounds and ash plumes not exceeding 2 km.
