LEONG Choong Yew
Director, Centre for Geohazard Observations
The mission of the Centre for Geohazard Observations is to install, maintain, and manage the Earth Observatory of Singapore’s geohazard observation networks in and around Southeast Asia. It aims to achieve high serviceability of the networks to consistently record quality data necessary to the fundamental research conducted by the Observatory.
The Centre for Geohazard Observations (CGO) installs, maintains, and manages the Earth Observatory of Singapore’s (EOS) geophysical and other field instrumentation stations and networks spread over several countries in and around Southeast Asia. The CGO also conducts geophysical surveys in aid of research, providing support in various technical matters that include the acquisition, computing, and archiving of geophysical data. The Centre strives to provide an innovative and conducive technological environment for our scientists both in the field and in the laboratory.
In providing effective technical and research support to the Observatory, CGO works closely with the Observatory researchers. Scientific requirements as well as technical and operational constrains are fully considered in all implementation and maintenance plans. CGO also works closely with our Southeast Asia collaborators, aiming to strengthen and expand the relationship to advance the regional geohazard research community.
