Numerous daily volcanic earthquakes continue to mark the activity of the Taal volcano in the Philippines.

In the past 24 hours, 38 volcanic earthquakes have been recorded.

The last field measurements, carried out on September 19, reveal an increase of 10 cm. of the water level in the western sector of Crater Lake. A slight inflation is always indicated.

The alert level remains at 1, not imminent eruption. It is advisable not to approach the main crater because of toxic gaseous fumes and the potential risk of sudden phreatic eruption.
