The Child of Krakatoa Awakes

At approximately 9:30pm local time (2:30pm GMT) on the 22 December 2018, a tsunami struck Indonesia’s Sunda Strait, which lies between the islands of Java and Sumatra, claiming over 430 lives. According to Indonesia’s disaster agency there are at least 1,500 injured, over 120 people still missing, and around 12,000 people have been displaced.

Geometry and Kinematics of the Main Frontal Thrust, Himalaya

This project aims to study the MFT and its associated fault splays by acquiring a densely-spaced set of high-resolution seismic reflection profiles across the fault tip in order to assess the geometry and kinematics of the fault.

People-Coral-Mentawai

People–Coral–Mentawai is a documentary short about the methods used by scientists at the Earth Observatory of Singapore to develop a timeline of earthquakes in the West Sumatra region.

Annual Report 2016
Nepal is the home to stunning landscapes and the tallest mountain range in the world. It is also the site of the largest active continental thrust fault called the Main Frontal Thrust. The collision of the Indian subcontinent and the Eurasian plate, which began about 50 million years ago, is still building the tallest mountains in the world and has produced many large, catastrophic earthquakes along the way.

Annual Report 2017
This annual report marks the end of the Earth Observatory’s first decade. At the onset, we conceived of a regional research and educational institution aimed at conducting basic geohazards research, headquartered on the campus of an up-and-coming university, NTU Singapore. Did we move significantly toward these goals during our first ten years? Are we contributing to making Southeast Asian societies safer and more sustainable? Are we likely, through the remainder of the century, to play a premier role in meeting the challenges...

Sumatran Tectonic Geodesy (SuGAr)

SuGAr has been observing surface deformation in Sumatra since 2002. The long time series are now a treasure trove of interesting signals and questions, and are providing us with a great opportunity to examine changes in time and space in deformation patterns related to the Sumatra subduction zone. In the last few years we have installed a large number of new stations, all with various scientific questions in mind.

Post-Disaster Damage Assessments: Room for Improvement?

On 25 April 2015, a 7.8-magnitude earthquake struck Nepal, destroying buildings and infrastructure across 31 of Nepal’s 70 districts. Approximately 9,000 people lost their lives to the earthquake that day, 22,000 suffered from injuries, and eight million were affected. I arrived in Kathmandu one week after the quake to support the government of Nepal in various response and recovery activities.

Continuous Haze Monitoring in Sumatra

This project will be the first to continuously monitor haze at its source in Indonesia and will provide a jumping-off point to investigate the impacts of haze on local and global environments.

Testing the Potential of Wave Gliders for Ocean Exploration and Seafloor Geodesy in SE Asia

Barbot's team is developing geophysical marine robots to probe the deformation of the seafloor. The end goal is to extend geodetic measurements offshore to better understand earthquakes, tectonic processes and tsunami hazards.

How Strong are the Rocks in the Sumatran Subduction Zone?

The highly active Sumatran Subduction Zone has produced more than four great earthquakes in the last decade. The first of these was the giant Mw 9.2 Sumatra-Andaman earthquake that ruptured on 26 December 2004. This devastating event was followed by three others – the Mw 8.6 Nias-Simeulue quake in 2005, the Mw 8.4 Bengkulu earthquakes in 2007, and the Mw 7.7 Mentawai tsunami-earthquake in 2010.
