Etna (Sicily, Italy): Less than 2 days after the previous lava fountaining episode (known as paroxysm), the 9th paroxysm took place from Etna's New SE crater this morning.
At first, it looked as if the volcano was going to produce the eruption already in the early morning hours: around 2 am local time, mild to moderate strombolian activity started at the New SE crater and soon became near-continuous. A lava flow started to flow from the eastern end of the deep fissure cutting through the cone, and slowly traveled eastwards. At the same time, volcanic tremor started to rise.
However, this activity slowed down again after around 3:30 am and ceased at around dawn, but only to restart about an hour later. From around 8 am, it again increased and this time developed into sustained tall lava fountains between around 9:30-10:30 local time. A tall ash plume rose approx. 4-5 km above the crater and spread into an umbrella cloud that drifted east and caused heavy ash fall in some eastern sectors and as far as Messina town.

Krísuvík (Southwestern Iceland): (4 Mar) The Icelandic Met Office (IMO) reported that seismicity on Reykjanes peninsula in the area between Krýsuvík, Kleifarvatn a Svartsengi volcanic system has been increasing during the past week.
The seismic activity started on 24 February accompanied by two moderate-to-strong volcano-tectonic earthquakes with magnitude M 5.0 and M 5.7 respectively and later that day another earthquake with magnitude M 4.8. Since the beginning of this unrest, 16 earthquakes above M 4 and 90 earthquakes above M 3 were detected by seismic network. The volcano-tectonic earthquakes were widely felt across SW part of the country including larger ones in the NW part as far as Ísafjörður.

...4 Mar:
The effusive-explosive eruption of the volcano continues at high levels characterized by strong strombolian activity from the Mackenney summit crater.
Judging from video record, another short lava-fountaining episode (so-called paroxysm) appeared from the summit crater yesterday that generated glowing lava bombs up to an approximate height of 500 meters above the summit as well as a tall and dense dark ash column that rose to estimated 11,500 ft (3,500 m) altitude extending about 25 km to the west of the volcano. Visibility of remaining lava fountains was very limited due to an ash clouds.
