| The coseismic deformation of the 2011
Tarlay earthquake, Myanmar |
| Supervisor: Mark
Simons, Kerry Sieh |
| Collaborator: Yu
Wang |
| Description: This project utilizes SAR interferometry
and pixel-tracking techniques to study the coseismic surface
deformation, and further to compare with field observations.
This is the first seismic event in the Indochinese peninsula
that has been well recorded by space geodetic techniques. |

| The interseismic deoformation of the
Pakistani Makran Subduction Zone |
| Supervisor: Mark
Simons |
| Collaborator: Zhenhong
Li |
| Description: This project is still in the
data processing stage. We aim to use InSAT technique to target
the interseismic deformation of the Pakistani Makran subduction
zone, where GPS data are very difficult to access. The images
we use show strong atmospheric disturbance with obvious influence
of dry and wet delays. We aim to use MERIS data as well as numerical
weather model to correct for the atmospheric signals. |

The relationship between the coseismic
and postseismic deformation
of the 2010 Maule Earthquake, Chile |
| Supervisor: Mark
Simons, Jean-Philippe
Avouac |
| Collaborator: Anthony
Sladen, Franciso
Ortega, Eric
Fielding, Benjamin
A. Brooks, Michael
Bavis, Christophe
Vigny, Andreas
Rietbrock |
| Description: This project is close to the
final stage. We use seismic waves, tsunameter, GPS and InSAR
to study the coseismic and postseismic slip associated with
the 2010 Maule earthquake in south-central Chile. |

| Multiscale InSAR Time Series (MInTS)
analysis of surface deformation |
| Supervisor: Mark
Simons |
| Collaborator: Eric
Hetland, Pablo
Musé, Piyush
Shanker Agram, Chris DiCaprio |
| Description: We develop an InSAR time series
technique that is analogous to GPS time series analysis technique.
This method is more delicate than other unkown InSAR time series
techniques, such as SBAS. |

| PCAIM joint inversion of InSAR and
ground‐based geodetic time series: Application to monitoring
magmatic inflation beneath the Long Valley Caldera |
| Supervisor: Jean-Philippe
Avouac |
| Collaborator: Andrew Kositsky |
| Description: We develop an efficient way to
combine the ground-based geodetic data and space-born measurements
such as InSAR images. This technique allows the user to generate
models with the complementing spatial and temporal resolutions
from different datasets. |

| A multiscale approach to estimating
topographically correlated propagation delays in radar interferograms |
| Supervisor: Mark
Simons |
| Collaborator: Eric
Hetland, Pablo
Musé, Chris DiCaprio |
| Description: We develop a tool to estimate
the topographically-correlated propagation delays (dry delay)
in InSAR images, based on the assumption that different signals
will have different characteristic spatial wavelengths. |

Submarine landslides along the Malacca
Strait‐Mergui Basin shelf margin:
Insights from sequence‐stratigraphic analysis |
| Supervisor: Kerry
Sieh |
| Collaborator: Joann
Stock |
| Description: We would like to understand the
potentiality of landslide tsunamis in the southeast Asia. This
is in response to the request from the Singaporean government,
who would like to know other potential tsunami sources in its
surrounding regions. |

Tsunami hazard from the subduction
megathrust of the South China Sea:
Part I. Source characterization and the resulting tsunami |
| Supervisor: Kerry
Sieh |
Collaborator: Kusnowidjaja
Megawati, Felicia Shaw, Zhenhua Huang, Tso-Ren
Wu,
Soon
Keat Tan, Tso-Chien
Pan |
| Description: We characterize the source region
of tsunamis generated along subduction zones in the South China
Sea. A numerical model of the worse case scenario is carried
out. |
