Volcanos

Roundup of Global Volcanic Activity

Stromboli (Eolian Islands, Italy): (8 Jul) Similar as during the last times, activity is fluctuating. After a few hours of increased lava effusions, it dropped and the new lava overflow creased again yesterday evening.

Etna (Sicily, Italy): (8 Jul) no significant changes: lava continues to effuse from the new fissure vent at the eastern base of the NE crater. A small hornito has grown at the vent. Tremor continues to climb slowly. Emanuela visited the active lava flows yesterday:

Vulcano (Eolian Islands): (8 Jul) Some impressions from La Fossa crater during our recent visit to Vulcano Island.

Kilauea (Hawai'i): (7 Jul) Elevated eruption activity continues on the East Rift Zone of Kilauea - a low shield, topped by a perched lava pond, is growing over the active breakout point of the June 27 breakout, on the northeast flank of Puʻu ʻŌʻō. Overflows from the lava pond are spreading mostly toward the north and northeast, but are too short-lived to advance much beyond the shield's base. Sulfur-dioxide emission-rates have been elevated since this June 27th flow.

At this summit of Kilauea, the eruption within Halemaumau crater continues and the summit lava lake has stabilized at ~34m (110ft). This large lava lake, now 160m (520ft) by 210m (690ft) wide, continues to produce intense glow at both sunset and sunrise in turn making for some excellent photo opportunities!

Seismic tremor levels have been low however, with an average of 15 to 20 earthquakes per week.
