Update: Mayon satellite observation

A bit of a good news on Mayon: PHIVOLCS has lowered the alert level to Alert Level 3. Hopefully, things will go back to normal and all those affected will be able to go back to their homes.

In the meantime, here are two of the latest satellite images of Mayon from Sentinel 2 since my last post. These images were taken last February 19 and March 1.

We can still see a bit of the new lava flow deposits (red areas from the crater), but clouds obscured most of the volcano. The satellite was able to capture the plume coming from the volcano. We can say this because the structure of the plume appears distinct from the surrounding clouds and we can trace it back to the crater. These plumes are likely a mixture of gases and aerosols escaping from the volcano. It’s possible to process these data further to separate the clouds from the plume so that we can be more sure, but I’ll leave that to people with more time in their hands.
