| Outline of Final Research Achievements |
The Philippines has many volcanoes due to subduction along its trenches similar to the tectonic setting of Japan. In this study, we have conducted geological surveys in Pinatubo, Taal, and Irosin volcanoes, located in Luzon, and Matutum and Parker volcanoes located in Mindanao Island, in collaboration with the Philippine Institute of Volcanology and Seismology (PHIVOLCS). We tried to reconstruct the eruptive history of these volcanoes, and establish a chronological framework of widespread tephras. Cored sediments were obtained from Paitan Lake, about 60 km northeast of Pinatubo Volcano. Ash layers were identified within these cores, and were given ages, with high precision.
