Llaima, 1 September 2009 (image copyright Victor Hazeldine, POVI)

The picture of Llaima above was taken by Victor Hazeldine on 1 September 2009 and comes from our friends at POVI (Proyecto Observación Visual Volcán Llaima). The view is of the east flank of the volcano, and shows abundant steam rising from thermally active areas around the summit. (Image copyright Victor Hazeldine.)

The following information about Llaima’s recent activity also comes from POVI:

The last summit eruption, as part of the current cycle started in may 2007, lasted 72 hour starting from April 4. The 3 block lava flows reached a total length of 12,5 km.

On April 24 and June 1st sporadic phreatic emission and red glow was observed from a 300 m long lateral active fissure on the eastern upper flank. Until mid July a weak red glow was observed on the western crater rim. The 350 m wide inner crater remains filled with pyroclasts and lava emitted during the long lasting current eruption cycle.

The following graphic shows the time table (chronology) of the current eruption cycle. Half column means weak to moderate ash eruption and/or lava flow (VEI 1). Long column means moderate to strong explosive strombolian eruption (VEI 2 -3).

Where is that report? Or is it a personal contact?
The POVI page shows the same info from about a few months ago. In any case, the LLaima is still “quiet”, and the Chaitén continues its dome-growing.

The above, with the photograph, came via a personal contact at POVI. Apologies if that should have been made clear.

Llaima is indeed ‘quiet’ (although seismicity has lately slightly increased) and Chaitén does indeed continue dome-building. I endeavour to cover both, but of course I am dependent for that on the information that comes my way.

No problem. It was only I thought it was published and I was not able to find it. Thanks for answering, anyway.
