The volcano's activity increased yesterday. CENAPRED counted no less than 544 small to moderate emissions during the 24 hours between 25-26 Feb.
An overflight with the support of the Navy yesterday afternoon showed that the most recent lava dome (number 48) had been destroyed by this activity. At its place, a new funnel shaped pit, approx 80 m deep was seen. At the bottom of this crater, a new lava dome of 20-30 m diameter already made its appearance.
The elevated activity had been preceded by volcano-tectonic earthquakes of magnitude 2.6 and 1.6 yesterday and the day before. The volcano's alert level remains unchanged at "Yellow phase 2."
