Reventador (Ecuador) - Report for 9 October-15 October 2019

IG reported that during 8-15 October seismic data from Reventador?s network indicated a high level of seismic activity, including explosions, long-period earthquakes, harmonic tremor, and signals indicating emissions.
Weather often prevented views of the summit area, although during clear conditions ash-and-steam plumes were visible rising sometimes higher than 1 km above the crater rim and drifting NW, W, and SW.
Crater incandescence was periodically observed at night.
Blocks were observed rolling down the flanks on 10 and 14 October.
