The launch of a new GVP website is scheduled for Monday, May 20, 2013.
A powerful pelean eruption on July 29, 1968 began a new eruptive period at Arenal volcano. This November 1968 photo shows the destruction of vegetation by powerful explosions that devastated a broad area on the western flank of the volcano. Ballistic impacts of ejected blocks stripped trees of leaves to distances as far as 5 km west of the summit. Photo by William Melson, 1968 (Smithsonian Institution)
The new website is getting closer! Here's a screenshot.
AVO reported that on 13 May seismicity at Pavlof increased at 0800 commensurate with the presence of an intense thermal anomaly at the summit observed in satellite imagery. On 14 May pilot reports and satellite images confirmed activity; a spatter-fed lava flow advanced about 0.5 km down the N flank.
IG reported that although cloud cover often prevented observations of Tungurahua during 8-14 May, ash plumes were observed almost daily. Strombolian activity was observed on most nights ejecting blocks sometimes 500 m above the crater; blocks that fell onto the flanks rolled as far as 1 km. During 9-10 May lava fountains rose 700 m above the crater.
The Smithsonian's Global Volcanism Program seeks better understanding of all volcanoes through documenting their eruptions — small as well as large — during the past 10,000 years.
