Map of the new lava flows from the 24 May breakouts

Kilauea (Hawai'i): Early in the morning of 24 May (at 06:50 local time), a sudden surge in lava supply caused the main lava tube carrying the lava underground away from Pu'u 'O'o to rupture. This resulted in two so-called surface lava breakouts located about 500 m N and NE from the cone, feeding two new large surface lava flows. Read all

Etna (Sicily, Italy): (18 May) The first eruption of Etna in 2016 has been rapidly changing, involving 3 of the 4 summit craters. After yesterday and partly today's strombolian activity from the North-East (and probably New SE) crater, a short, but violent phase of lava fountaining (paroxysm) occurred at the main summit vent, the Voragine. After this, the eruption has become dominantly effusive and is now producing a lava flow from a fissure vent on the lower eastern flank of the New SE crater. The lava flow, with one main channel and few secondary branches, is currently traveling into the Valle del Bove. Read all
