During the past day, the latter had been more intense, while today, activity seems to have focused towards the main vent of the New SE crater, formerly known as the "saddle vent", now a deep crater half open on its SE side due to the dramatic changes during the recent paroxysms. This is nicely visible in Domenico Mazzaglia's photo attached (source on facebook).
Glowing lava bombs are being ejected to heights of up to 100-200 m and often land on the crater's outer slopes.
Earthquake activity has declined for now and volcanic tremor levels show no significant variations. However, this can change quickly.
