This poster characterizes the particle morphology of the andesitic and rhyolitic tephra deposits obtained from the cores in Sibuyan sea and Bohol sea, Philippines. The goal was to come up with the physical attributes of the two compositionally different tephra, which can be used in the interpretation of eruption style, fingerprinting and correlatio...

The SW sector of Mount Natib, a potentially active volcano in the Bataan volcanic arc in western Luzon, is the site of a mothballed nuclear power plant that members of the national legislature have proposed to activate. Detailed geological fieldwork was conducted to assess the capability of the volcano and to identify any volcanic hazards it might...

The study of marine ash layers is important for identifying explosive eruptions and their possible impact on the marine environment. In the Philippines, there is additional benefit because tephra are not well preserved on land due to extensive erosion. Here we focus on three tephra layers (1-2 cm thick) preserved in a 960 cm-core, MD06-3057, from t...

Piston coring on the Benham Rise in the western Philippine Sea during the Marco Polo 2 cruise of R/V Marion Dufresne in 2006 provided a rare opportunity to study tephra deposits offshore the Eastern Luzon volcanic arc. Four tephra layers were analyzed from the upper 7 m of core MD06-3047 (~450 km from the arc, 2510 mbsl): A 6 cm-thick black ash ove...
