Etna (Sicily, Italy): The alert level for the volcano was raised to "orange", as an increase of volcanic tremor has been recorded. This could precede another upcoming phase of more vigorous activity, which remains to be seen, but it suggests that a new batch of magma could be rising inside the volcano's conduits.
In the last days, the intermittent strombolian activity from the New SE crater and the new cone in the summit crater Voragine had been decreasing significantly and become very sporadic.
Today, weak to moderate steam and ash emissions have been occurring from the New Southeast Crater, creating small plumes that were quickly dispersed eastwards by strong winds. The volcanologists only observed sporadic events.

Loihi (United States, Hawaiian Islands): (13 May) On 10 and 11 May the Hawaiian Volcano Observatory (HVO) recorded increased seismic activity at the submarine volcano.
Beginning about 03:00 local time on 11 May and continuing through the morning on 12 May, HVO detected more than 100 earthquakes beneath the volcano, including 79 magnitude-2 (M2) and 19 magnitude-3 (M3) and above. This is a significant increase above long term background rates of fewer than 3 earthquakes per day at Loihi, generally with magnitudes less than 2. The number of earthquakes peaked at 14 per hour between 13:00 and 14:00 local time on 11 May and decreased thereafter. Since the early morning hours on 12 May, earthquake rates have been less than 4 per hour.
