Volcanic activity worldwide 5 Aug 2014: Kilauea

Tuesday Aug 05, 2014 21:00 PM |

Kilauea (Hawai'i): (4 Aug) This map (USGS) shows the June 27th flow at Puʻu ʻŌʻō in Kilauea’s East Rift Zone. The area of the flow as mapped on July 18 is shown in pink, while widening of the flow as of July 29 is shown in red.

These flows continue to progress slowly in a NE direction roughly 5km (3mi)from Puʻu ʻŌʻō, mostly on top of older flow fronts. There was no significant change in ground tilt at Puʻu ʻŌʻō over the past few days, and two small lava ponds remained active on the south side of Puʻu ʻŌʻō's crater.

The most recent sulfur-dioxide emission-rate measurement was 600 tonnes per day (from all East Rift Zone sources) on July 31, 2014.

Etna (Sicily, Italy): No significant changes have occurred at the volcano recently. Lava continues to arrive at the vent(s) at the eastern base of the NE crater, where strombolian activity is building up a complex cone and several small lava flows are spreading towards the Valle del Bove. ...

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. ... [more]
