Canlaon volcano (Philippines): new cracks in crater area after 6 Feb 2012 earthquake

Tuesday Feb 21, 2012 19:54 PM | BY: T

Three 50 m wide cracks have appeared on on the upper flank of Canlaon volcano (also spelled Kanlaon) near the crater after the M6.7 earthquake on Negros island in the Philippines on 6 Feb 2012.
According to PHILVOLCS, the Philippine volcano monitoring agency, the cracks were caused by the earthquake and are not likely a precursor for a new eruption, which would be the first since 2006, although Canalon is one of the country's most active volcanoes. A more detailed investigation is planned and the mountain was for now closed for climbers.
Erik Klemetti on his more detailed post on Eruptions Blog mentions rightly that a major hazard from Canlaon volcano are landslides and mud flows, and that these are not necessarily related to an eruption, but can be triggered as well by heavy rain and gravitational instability caused by earthquake movements. In this context, the cracks should be examined and monitored carefully.

Canlaon volcano might be preparing for a new eruption. PHILVOLCS observed a remarkable rise in its seismic activity. [more]
Saturday, Nov 11, 2006

On 2 November, PHIVOLCS lowered the Alert Level for Canlaon from 1 to 0. Since 26 July, 2006, no more ash explosions occurred and steam emissions and seismicity were low.

Saturday, Jul 29, 2006

Based on interpretations of seismic data, an explosion at Canlaon that lasted more than 10 minutes occurred on 23 July. An ash column was not observed due to cloud cover. Trace deposits of ash fell up to 9 km ENE of the crater in the neighborhoods of Pula, Malaiba, and Lumapao. On 24 July, PHIVOLCS reported a total of 16 volcanic earthquakes, 3 short-duration tremors, and 2 earthquakes indicating small explosions. Ash was not observed.

As PHILVOLCS reports, brief periods of ash and steam emissions continue at Kanlaon Volcano.  This is a manifestation of the ongoing low-level unrest.  Alert Level 1 remains enforced.   For the latest significant event and bulletin issued, see the Chronology of Events file published by PHILVOLCS.

Weak activity continues at Kanlaon volcano: Between 3 and 12 June, 4 small phreatic explosions occurred at the summit crater of Kanlaon volcano (3 June, 10 June, 2 times on 12 June). The explosions produced mainly steam and gas as well as small quantities of ash to heights up to 1000 m. Light ash-fall occurred on the upper slopes of the volcano. An exclusion zone of 4 km around the crater is being maintained. --->more on Kanlaon volcano
