New EOS Study on the Dangers and Impacts of Unconfined Pyroclastic Flows

Volcanic eruptions are sometimes accompanied by clouds of ash and hot gases that travel down the slopes of volcanoes at tens of kilometres per hour. These clouds, called pyroclastic density currents (PDCs), are some of the deadliest volcanic hazards. And as we cannot easily study them in real-time, we took another approach to quantify some of the features that make them so dangerous: their speed, temperature, height, and how far they travelled.

The Mw 7.3 Earthquake Off the Coast of Flores Likely Occurred on a Known Fault

A major earthquake struck off the coast of Indonesia in the Flores Sea on 14 December 2021 at approximately 11:20am (Singapore time). According to the United States Geological Survey, the magnitude-7.3 earthquake occurred off the north coast of Flores, about 110 kilometres (km) from Maumere, at a depth of 16 km. The Badan Meteorologi, Klimatologi, dan Geofisika (BMKG), the Indonesian meteorology, climatology, and geophysical agency, issued tsunami warnings for the region but no significant tsunami was detected.

Unraveling Myanmar’s Underground Structure to Better Prepare for Future Geohazards

Lying at the junction of several tectonic plates, Myanmar is exposed to geohazards such as earthquakes, tsunamis, and volcanic eruptions. To help prepare for these hazards, scientists produce hazard assessments using their understanding of the region’s geology and tectonic activity. They seek to answer questions such as: how do the tectonic plates interact with each other, how deep the magma is, where the faults are, and what kinds of earthquakes can we expect? 

This proposal seeks funding to develop a long-term research program on Sundaland, focusing on the two of the largest rivers in their discharge in Southeast Asia: Chao Phraya in Thailand and Mekong

Unsustainable sand extraction at the current rate could possibly lead to serious impacts on the environment and local communities, and affect international relations.
