The new lava flow on the upper Sciara del Fuoco this evening
Stromboli (Eolian Islands, Italy): Activity continued throughout the night and the lava flow has reached the sea. At the moment, activity has decreased a bit.
...17 Apr:
The new lava flow is well alimented and has reached several hundred meters down on the Sciara del Fuoco. Explosive activity continues as well.
...17 Apr:
A new larger lava flow from the NE vent has started this afternoon to descend the Sciara del Fuoco, accompanied by glowing rockfalls and strong tremor. The eruption was preceded by very large strombolian explosions during the morning.
Etna (Sicily, Italy): It seems likely that another paroxysm is in the making at the New SE crater: Strombolian explosions have continued throughout the night and this morning, and have been intensifying. Lava seems to have appeared at several vents on the fissure cutting through the New SE crater and the tremor signal is steeply rising.
Popocatépetl (Central Mexico): (17 Apr) Activity has dropped a bit but remains essentially unchanged. CENPRED reported 1-2 emissions of steam and minor ash amounts per hour today, a steam and gas plume rising up to 1 km as well as continuing glow at the crater.
Nevado del Ruiz (Colombia): (17 Apr) Strong degassing and minor ash venting continue creating a plume reaching 1000 m above the crater today. The seismic swarm has decreased in strength, but goes on.
