Mayon, on Luzon Island in the Philippines, entered a new eruptive phase on 13 January 2018, according to the Philippine Institute of Volcanology and Seismology (PHIVOLCS), Philippines’ Geological Agency. This phase included steam-driven eruptions and flows from a new lava dome growing at the summit of the volcano.

A good understanding of the time scales of volcanic unrest and the dynamics of magma ascent are critical for the preparedness and mitigation of eruption hazards.

Volcanoes as Agents of Change in Human History – Part 1

Humans are fabulous agents of geologic change. What do I mean by this? We reduce the height of mountains via mountaintop mining to obtain energy resources. We blast through a mountain to make a road cut, or tunnel. We make new lakes by building dams for hydroelectric power. Indeed, we humans are capable of changing the landscape or environment (or climate for that matter) at rates much faster than normal geologic processes.

This pilot project will investigate the nature and timing of past uplift events to help characterize the nature and timing of large earthquakes on the Manila Trench.

In the 2nd year of this study, we aim to reconstruct the impacts of the 1897 (Ty1897) typhoon in Tacloban, Philippines using a combination of geological/geomorphological evidence, histor
