About

Siyuan Zhao's work focuses on using geodetic techniques (e.g., InSAR and GPS) to investigate the crustal deformation caused by earthquakes, volcano activities, or hydrological effects spatially and temporally.

Research interests

Currently, Siyuan's research involves:

1. Generating a broad-scale kinematic model for the Australia-Indonasia-New Guinea collision zone using GPS and earhquake slip vectors.

2. Investigating the coseismic and post-seismic deformation caused by 2018 Lombok earthquake sequence based on InSAR and seismic datasets.

3. Understanding the influence of 2018 Lombok earthquake sequence on the unrest Rinjani-Samlas volcanic system by modelling the time-dependent volcano pressure source and analysing the inflation/deflation rate of the volcano edifice in different periods.

4. Spatiotemporal monitoring of groundwater resources based on InSAR deformation and groundwater level measurements.

5. Investigate the coupling distribution along the Java-Timor subduction-collision transition zone.

6. Investigate the relative age of the structures within the Papua New Guinea Fold-Thrust Belt based on the morphtectonic indicators and satellite imagery.
