In early 2016, the Earth Observatory of Singapore (EOS) installed a network of seismic stations in northeastern Bangladesh called TREMBLE - Temporary Receivers for Monitoring Bangladesh Earthquakes. The aim of TREMBLE is to monitor seismicity and study body waves - seismic waves that move through the earth’s interior. TREMBLE also enables shallow tomographic studies. It is an ongoing collaboration with Dhaka University’s Department of Geology.

Bangladesh has a long history of floods and earthquakes. With the 8th largest population in the world, it has a limited land area of just 147,570 square kilometres (km2). It also lacks infrastructure that can withstand earthquakes.

Having this many people in such a small area is potentially disastrous in the event of an...

Typhoon Hato–one of the strongest typhoons in 53 years–struck the coasts of southern China on August 23, 2017. The typhoon, which claimed 26 lives and resulted in billions of dollars in economic losses, generated widespread storm surge flooding in the coastal cities of Macau and Zhuhai as it coincided with an usually high astronomical tide.

While Macau and its neighbouring city, Zhuhai, frequently experience storm events, the severity of flooding during Hato was the worst in recorded history.

Three days after the event, our survey team–a collaboration between the Earth Observatory of Singapore (EOS), National University of Singapore (NUS), and Tsinghua University–was deployed to Macau and Zhuhai to investigate the impacts left by Typhoon Hato.

In February 2017, scientists from the Earth Observatory of Singapore (EOS) led an earthquake geology training camp in Myanmar and Thailand.

A diverse group of geology students – hailing from Thailand, Laos, Myanmar, Vietnam, Cambodia, Malaysia, China, and the USA – joined the training course led by Dr Wang Yu, a Research Fellow at EOS, and Visiting Professor Ray Weldon from the University of Oregon.

The course was designed to allow scientists to share their knowledge about active fault trenching and paleoseismology with geology students who may not have had prior field experience.

Central to this training course was the idea that scientists and students from Southeast Asia countries could be equipped with the necessary skills and knowledge so that...
