None of these quakes was strong enough to be felt, but the very sensitive monitoring network of the Vesuvius volcano observatory of INGV (also responsible to monitor the Phlegrean Fields, and Ischia volcanoes) has detected an increase of micro-seismic activity already since October this year. In total, there have been 212 weak tremors in the area of the caldera. 126 quakes of these occurred between Pozzuoli, the Solfatara-Pisciarelli area and the Gulf of Pozzuoli.

La Palma (Canary Islands (Spain)): Activity continues with no significant changes, with similar intensity as during the past days, while on a very gradually decreasing trajectory. The eruption is now mainly effusive (i.e. producing lava flows). At the vents, explosive activity has been only intermittent and comparably weak recently, although still able to produce plumes rising to up to 2-3 km during phases of more intense activity such as this morning.
Most of the time, however, only dense steam plumes rise from the craters, while fluid, degassed magma continues to arrive and flow through a tube system to arrive at the new active sea entry, where a second delta is now growing. Watch some videos taken by staff from IGN:
