VoW: Mayon

We would have liked to reprint a striking image of Mayon Volcano taken from space, and all that NASA had made available as of posting was this truly disappointing “turn-of-the-satellite” image:

  • According to news articles, PHIVOLCS reported that on 14 December incandescence emanated from the lava dome in Mayon’s summit crater and incandescent material traveled as far as 3 km down the S and SE flanks. At least five minor explosions were detected by the seismic network.
  • According to a news article, INETER reported that an explosion of ash and gas from Concepción on 11 December produced a plume that rose 150 m above the crater.
  • OVPDLF reported that on 14 December an eruption from Piton de la Fournaise was preceded by a seismic crisis and summit deformation. Sub-parallel fissures along the rim of Dolomieu crater fed lava flows on the S slope.
