From 14:46:10 H UTC this July 3, 2019, a paroxysm concerns the center-south zone of the crater terrace of Stromboli.

In particular, two main explosive events were distinguished at 14:46:10 H and 14:46:40 H UTC, respectively. The sequence was preceded at 14:44 h UTC by lava overflows of all the active mouths of the crater terrace towards the Sciara del Fuoco.

The monitoring networks recorded at 17:16 hours (15:16 UTC), a stronger intensity explosion.

Field Ingv personnel observed an eruptive column that rose for at least 2 km above the south-west dispersal top zone. The paroxysmal products, including bombs and lapilli, fell back onto the flanks of the volcano, causing a series of fires in the vegetation.

A start of panic is reported in Ginostra, village distant 2 km from the terrace.

The phenomenon in question is also visible on the seismic plot, which also shows explosions closer to 20 minor explosive events.

After the paroxysmal phase, the tremor signal is decreasing.
