*Etna update, 9 February 2012 (INGVカターニア)
After more than 12 days of mild Strombolian
activity, Etna's New Southeast Crater has produced
a new paroxysmal eruptive episode on the early
morning of 9 February 2012: This event was less
violent than its predecessors, but lasted more
than 5 hours. A lava flow descended toward the
Valle del Bove, stagnating before it reached the
valley floor.

未知の断層が動いた可能性。
An "unmapped" fault line caused the magnitude-6.9
quake that shook Dumaguete and its neighboring
regions on the afternoon of February 6, according
to the Philippine Institute of Volcanology and
Seismology (Phivolcs).
The earthquake was caused by the sudden shifting of
two tectonic plates in the Visayas area. The shift
was from a "blind fault" some 20kms below the
earth between Negros and Cebu.
Dr. Ishamel Narag, chief of Phivolcs' Seismological
Observation and Earthquake Prediction Division,
said that the February 6 earthquake was not
traced to any known existing faults in the area,
suggesting the presence of a previously unmapped
fault.
