Volcanic Mudflow

We're on our way to Olongapo City that time. It's a long trip from the capital town of Zambales, Iba. Both Olongapo and Iba are in the same province. Passing by this place, it looks like a desert. It was told that the volcano Mount Pinatubo had a violent eruption in early 1990s, and it has buried large parts of Zambales and nearby provinces.

"Lahar" which is volcanic mudflow has flown through rivers too. Those in the pictures are some of them. I have seem a number of them while in Zambales.
