Volcanic activity worldwide 30 Jul 2014: Kilauea

Wed, 30 Jul 2014, 21:00

Kilauea (Hawai'i): The June 27 flow front has advanced more rapidly over the past four days, and is now 4.2km (2.6mi) from the vent (Seen in first photo below). This recent increased advance rate is due to the confinement of the flow against the slopes of an older perched lava channel, from 2007. The advance rate will likely drop in the coming days as the flow passes the confines of the perched channel and spreads out on flatter topography. Read all

Volcanic activity worldwide 21 Jul 2014: Kilauea

Mon, 21 Jul 2014, 21:00

Perhaps the most interesting feature in the new crater at Puʻu ʻŌʻō is the pit formed on the southern side of the crater floor. There, a small lava pond roughly 10 m (~30 ft) across has been sporadically overflowing and sending lava toward the deeper central part of the crater. View is to the south.

Kilauea (Hawai'i): Kīlauea continued to erupt at its summit and within the East Rift Zone, and gas emissions in both areas remained elevated. There was no significant change in tilt recorded at the summit, and the lava lake level was relatively steady over the past week leveling at ~30m (98ft). Read all

Stromboli volcano (Eolian Islands, Italy) eruption update: new lava flow on the Sciara del Fuoco

Mon, 7 Jul 2014, 07:43

New lava overflow on Stromboli's Sciara del Fuoco this morning (INGV thermal webcam)

After a weekend with comparably low activity and no lava overflows, a new surge of lava effusion has started and a small lava overflow is again active on the upper Sciara del Fuoco. The surge of the magma caused a partial collapse of the NE hornito (N2 vent) at 05:35 UTC, producing an impressive avalanche resembling a pyroclastic flow. Read all
