Eruption of Kanlaon volcano yesterday (PHILVOLCS)
According to PHILVOLCS, the eruption which lasted less than 30 minutes was entirely steam-driven (phreatic or hydrothermal), i.e. caused by overheated ground water flashing into steam inside the hydrothermal system overlying a (probably small) body of magma, but no magma itself was projected to the surface.
A small plume of ash rose approx. 400 m and caused minor ash fall in San Miguel, Gintubdan and Araal in La Carlota, Negros Occidental.
PHILVOLCS recorded ongoing inflation (sign of magma intruding at depth), small earthquakes (3 volcano-tectonic events on 17) and observed steaming from the volcano producing a plume that rose about 300 m.
The alert level remains at 1 as the volcano's hydrothermal system is highly unstable and could produce sudden explosions again at any time. It could of course also evolve into a more sustained magmatic eruption if magma continues to rise towards the crater.
