Seismicity at Lokon volcano during 2015 so far (VSI)
A mild gradual increase in seismic activity over the past 2-3 months has been noted. The latest bulletin issued yesterday reminds the public to keep a safety distance of 2.5 km around the Tompaluan crater, where new fractures were formed during and after the eruption on 13 Sep last year. Sudden phreatic or phreatomagmatic explosions (caused by overheated steam and/or contact between water and magma), with associated ballistic ejections, pyroclastic flows and ash falls could occur any time with little to no warning.
