Indonesia is known for extremely active plate tectonics and a series of gigantic earthquakes including the well-known 2004 Mw 9.3 earthquake. Since 2000, about 50% of global seismic energy release took place in and around the Sumatra island, despite that its area only occupies a few percent of... Read more

Detailed and high-resolution imaging of earthquake rupture processes is critical to understanding the initiation, propagation, and termination of earthquakes, and hence their fundamental physics and the seismic hazard. As a long-term effort in my group, we have been working extensively in... Read more

A paucity of suitable equipment has seriously limited our understanding of the Earth’s structure and tectonics in South East Asia. Now, however, seismic nodal instruments are revolutionizing the acquisition of low-cost, high-quality seismic data in industry and academia. The instruments... Read more

To better understand the earthquakes and associated tectonic setting and ground shaking, we study earthquakes in Southeast Asia, the most seismically active region on the earth. We also study significant earthquakes at a global scale, as they usually are recorded by dense observations, providing... Read more

Myanmar, located on the eastern margin of the ongoing Indo-Eurasian collision system, has experienced a complex tectonic history. The region is characterized by the southward extrusion of the Shan-Thai plateau to the east and the highly oblique subduction of the India plate to the west. A large... Read more

Past Projects

Rupture durations and other physical processes of tsunami earthquakes show strong variations and the underlying mechanisms of both earthquake and tsunami generations have not been understood. Here we propose to revisit the tsunami earthquakes in Sumatra (2010 Mw7.8) and Java (1994 Mw7.8, 2006... Read more

To better understand the earthquakes and the associated tectonic setting and ground shaking, we propose to study earthquakes in SE Asia, the most seismically active region on the earth, with a series of broadband waveform modelling tools. The proposed works include systematic determination of... Read more

Tsunami earthquakes are defined as the events that rupture near the trench and characterised by longer source duration and large tsunami waves following the earthquake. Despite the hazard imposed by tsunami earthquakes, physical processes (e.g. duration) of tsunami earthquakes and the underlying... Read more
