The volcano remains restless. A small explosion occurred Saturday morning at 09:19 local time.
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.

Kanlaon volcano (Philippines) - Smithsonian / USGS Weekly Volcanic Activity Report for 15 June-21 June 2016 (New Activity / Unrest)
Based on visual observations, PHIVOLCS reported that a series of three eruptive events occurred at Kanlaon on 18 June, beginning at 0919 and lasting 27 minutes. These events were recorded by the seismic monitoring network as consecutive explosion-type earthquakes that lasted 30, 42, and 29 seconds, respectively. The first event, a steam-and-gas explosion, generated a light gray-to-white ash plume that rose 1.5 km above the crater and then later to 3 km. ... Read all

Two small explosions occurred at the volcano yesterday evening, at around 18:20 and 19:18 local time. An ash plume rose to approx. 1500 m above the summit and some freshly ejected incandescent bombs could be seen at the crater rim. ... Read all
