During that time Pinatubo is already some kind of activity. There will be minor eartquakes/eruptions from time to time.
And i remember few months before the eruption my father told me to  help in evacuating the aborigines (using SARAO jeepney) who are living close to pinatubo. In June 15, 1991 the eruption of the century happened. It literally blew apart sending ash and rocks into the air 40km up and 300 m of the summit lost. Afterward a typhoon came and the situation got worse. I remember my father was on top of the roof with a shovel clearing mud, otherwise the roof will collapse.

Lost lives, lost property , lost livelihoods but the most affected were the aborigines because it took some years before they can go back to their villages. There were no suitable land to grow crops again, which is their source of food and livelihood.

But now what pinatubo have taken it´s giving back because of the tourist coming in. GOD is good! The locals even the aborigines were given chances to be guides for tourists who wants to experience Pinatubo Trekking and explore its surrounding environs.
