The Irrawaddy (Ayeyarwady) is one of the less known large rivers in the world and the second largest river of Southeast Asia in water discharge, after the Mekong.

The country of Bangladesh sits in a complex tectonic region on the eastern side of the India-Asia collision zone.

For this project we propose a multi-proxy (trace elements, water inclusion and carbonate δ18O) study on speleothems collected from sites along a SW-NE transect in a region dominate

This project is a multi-lateral collaboration between several EOS researchers and colleagues at other research institutions to study the tectonics and earthquakes of Southeast Asia.

Annual Report 2017 - Research

Home to more than 50 million people, Myanmar is shaped like a giant kite with a long tail that sweeps down along the Andaman Sea.

Beneath the surface, invisible dangers affect Myanmar’s growing population, making it one of the most earthquake-prone countries in the world. In the north, mountain ranges mark the northeast limit of the Indian tectonic plate, which has been colliding with the southern edge of the Eurasian plate for tens of millions of years. It is this interaction that has helped push up the Himalayan Mountains and the Tibetan Plateau in the far north of the country.

To the east, the Shan Plateau rises high above the central Myanmar basin. Ribbed with mountain ranges and broken hills, it hides a 700-kilometre-wide system of active faults, creating hazards we know little about.

Extending north to south, the 1,500-kilometre-long Sagaing Fault splits Myanmar in half, running below the economic centre of Mandalay, through the new capital of Nay Pyi Taw, alongside the thriving metropolis of Bago, and to the west of the country’s largest city, Yangon. When set into motion, strike-slip faults like this one tear the earth apart when slabs of crust slide sideways against each other.

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 posed to Southeast Asian societies by climate and sea-level change, volcanic eruptions, earthquakes, tsunamis, and river hazards?

Today's Quake in Myanmar is a Reminder of How Active the Sagaing Fault is

Very early in the morning on Friday, 12 January 2018, Myanmar was struck by a magnitude-6.0 earthquake. Residents in the two capital cities, Yangon and Nay Pyi Taw, were able to feel the quake that had originated 40 kilometres west of the Sagaing Fault in Central Myanmar.

In the video below, Dr Wang Yu, a Research Fellow at the Earth Observatory of Singapore, suggests that today’s earthquake is a reminder of how active the Sagaing Fault actually is.
