The Myanmar-India-Bangladesh-Bhutan GPS network began operation in 2012 and now comprises 33 continuous stations across four countries, plus 113 survey stations we have added in the past several years. It has already collected a wealth of observations that reveal important features of the... Read more
We are building a holistic understanding of regional sea-level change that includes influences from both land-height and sea-surface change. Towards this, we are using geodetic (GPS and InSAR) data to study the rates and sources of groundwater-related subsidence in cities around Asia. In a... Read more
The Sunda megathrust has received a lot of attention in the last decade. However, information on the Sumatran fault zone (SFZ), which traverses the entire 1900-km length of Sumatra, is still lacking. The SFZ is a right-lateral strike-slip fault, accommodating a significant portion of... Read more
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... Read more
We propose to use geodetic data from InSAR to map subsidence at three peatland locations in Borneo. Maps of subsidence in peatlands reveal patterns of CO2 emissions because long-‐term subsidence of peatlands is driven by fire and aerobic decomposition. Together, fire and aerobic decomposition...

We are 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.
There is a seismic gap on the Sunda megathrust at the latitude... Read more
This project aims to assess sea level variability over the 20th century with precise and accurate data.
These variations are traditionally mapped by data derived from tide gauges, but few long tide records exist from Southeast Asia.
In order to gain a... Read more
Mass loss from ice sheets and mountain glaciers is making major and accelerating contributions to rising sea level. The effects on sea level from this melting ice will not be spatially uniform, but will instead have dramatic regional variations due to the effects of the so-called “... Read more
