Etna (Sicily, Italy): A series of earthquakes shook the flanks of Etna volcano during the past days. Since the afternoon of 31 Dec 2020 until this morning, a swarm of tremors has occurred at depths of 10-15 km mainly under the southern flank of the volcano.
A total of almost 40 quakes of magnitudes of up to 3.8 have been recorded, most of them on 31 Dec and early 1 Jan. The strongest quakes were widely felt by people living on the southern slopes of Etna.

Merapi (Central Java, Indonesia): Over the past several days, seismic activity from the Merapi volcano – Indonesia’s most active – has been increasing significantly, suggesting that a more intense phase of volcanic activity is on its way.
Indonesia’s volcanologists recorded a record number of volcanic earthquakes under the volcano, namely 720 quakes yesterday and 680 the day before, both of which represented new records in recent months. The average for the month of November had been around 30 before these record figures. It is particularly worrying that many of the newly detected tremors may be caused by rock-breaking magma which has the power to create new magma conduits or widen existing ones inside the volcano itself. These tremors are known as volcano-tectonic quakes and can be quite dangerous.
