The Phivolcs lowered the Mayon alert level to 3, to reflect the general decrease in instability:

- a decrease in seismic activity, despite a top-down effusive activity,

- sporadic degassing associated with small plumes, and low fountaining,

- a deflation of the lower slopes which took place on February 20th,

- a decrease in the flow of sulfur dioxide.

The recommendation not to enter the zone of 6 - 7 km radius of the PDZ remains in force.

Images of Planet Labs comparing the situation of Kadovar in September 2017 and March 3, 2018, via Simon Carn, show not only the extrusion of the dome, but also the disappearance of a substantial part of the east coast of the island, following the activity of recent months.

A local government control visit shows that as of March 5th, the importance of summit emissions and the costal vent has decreased slightly.
