‘Two lava domes growing’ at Mayon 16 December 2009

A press report in the Philippines quotes Phivolcs head Renato Solidum as warning that two lava domes are currently growing in Mayon’s crater:

Two lava domes have formed at the crater of the Mayon Volcano, raising concerns among government volcanologists over the possible extensive damage should these collapse and a major eruption occur. Renato Solidum, director of the Philippine Institute of Volcanology and Seismology (Phivolcs), said the domes were ‘growing’ and that an aerial survey must be conducted to determine the hazards these would pose to residents living within the danger zone.

CNN reports that 30,751 people have so far been evacuated from around Mayon – the figure comes from the Philippines Red Cross. Albay Governor Joey Salceda is quoted in an Abu Dhabi newspaper as saying that he expects the evacuation to be completed today, although given time differences it’s unclear whether the ‘today’ in question is 16 or 17 December.

The BBC have a video of lava being erupted from Mayon; it looks lumpy and fragemented. Over at Eruptions, Dr Erik Klemetti observes in his excellent Mayon update for today that ‘it looks pretty clear to me that the lava flow isn’t as much low viscosity flows as crumbling, glowing dome rock’.

N.B., the Phivolcs website remains obstinately non-functional. [UPDATE 17 December 2009 – it’s working again.]
