The summit of Pinatubo is seen from the E at Clark Air Base in 1992. The unvegetated peak near the center is the southern rim of the new caldera and summit. The northern caldera rim lies about 2/3 of the distance between the summit and the unvegetated peak to the right, which is the relict caldera rim of ancestral Pinatubo volcano.
