San Cristobal volcano news & activity updates

San Cristobal volcano (Nicaragua) activity update: increased SO2 emissions, tremor pulses and small earthquakes

lundi sept. 17, 2012 10:05 | AUTEUR : T

Elevated SO2 emission continues to be measured. On 15 Sep, SO2 flux was measured at 3,054 tonnes per day. INETER suggests in its latest press release yesterday evening that this increase might have been caused by a liberation of the conduits. Early yesterday, between 6:50 - 827 am local time, there was a pulse of tremor and 2 week earthquakes at 7:47 a.m. and 7:51 a.m. which could not be felt (see image from yesterday's update). Today, the seismicity has been rather low again.
