Between 1-15 Feb, a total of 350 seismic events or about 21 per day on average were registered, including 233 long-period signals interpreted to be caused by fluid movements, 8 so-called tornillo long-period quakes, one of which lasted 148 seconds, and 3 pulses of volcanic tremor (possibly indicating magma movements).
