The mission of the Centre for Geohazard Observations is to install, maintain, and manage the EOS’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.
Supporting Scientific Research
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.

MIBB GPS Network
MIBB GPS Network
EOS' Myanmar-India-Bangladesh and Bhutan GPS Network comprises stations along North-South and East-West transects.
The North-South transect is intended to measure the convergence across the Himalayan front and the Shillong Plateau.
The East-West transects will reveal the nature of strain accumulation across both the fold and thrust belt of the Indo-Burman Range and northern Sagaing fault.
The networks, linked by a satellite-based communication system, monitor the tectonic motion in several earthquake hotspots within South and Southeast Asia, thus providing essential information for scientists to understand the earthquake potentials from these mega fault-systems on earth.
The information collected from these monitoring stations also has the potential to improve the current tsunami early warning system after an major earthquake event. CGO at EOS is fully capable of selecting the optimal site for the GPS monitoring stations, installing and maintaining these...

Ground-penetrating Radar (GPR)
Ground-penetrating Radar (GPR)
(GPR) is a technique that uses high-frequency radio waves to image the subsurface of the Earth. This technique is often used by our scientists to study sediment deposits related to coastal hazards in Southeast Asia.
The usage of the ground penetrating radar (GPR) at EOS provides scientists the useful information about the material properties in the shallow depth of the earth. This technique has been widely used in many other research fields from decades.
Scientists in EOS use this technique extensively to study the sedimentology related to the coastal hazards in Southeast Asia, such as the trace of the unusual typhoon events, and the deposits from the tsunami waves. EOS also uses GPR in Nepal to sense the location of the giant fault at the root of the Himalayan mountain range. This giant fault ruptured in 1934, and caused great destruction to the Nepal area.
The CGO and the scientists at EOS are fully capable of acquiring, processing, and interrelating the GPR...

Pandemics & Natural Hazards: The Way Forward for Earth Scientists in a Global Lockdown
Pandemics & Natural Hazards: The Way Forward for Earth Scientists in a Global Lockdown
14 May 2020
Pandemics & Natural Hazards is a special series for the EOS Blog which looks at the compounding impacts of coinciding disasters. This third commentary is a contribution from EOS’ Centre for Geohazard Observations.
The daily coverage of the novel coronavirus disease (COVID-19) in the media has given the public an insight into how the crisis has impacted the healthcare sector. We’ve seen footage of hospitals inundated with stricken patients, hospital staff begging for supplies, and the global race to find the medical holy grail of the moment – a COVID-19 vaccine.
But what about the other sectors of science that are not directly linked to the coronavirus? How are they coping with, even transforming in, this pandemic and the ensuing cross-border lockdowns?
The Earth Observatory of Singapore (EOS), for example, is an Earth Science research institute that conducts fundamental research into natural hazards and disaster risk reduction in southeast (...

New Seismic Network Sheds Light on Myanmar’s Tectonic Activity
New Seismic Network Sheds Light on Myanmar’s Tectonic Activity
20 Nov 2017
Scientists have long known that Myammar is tectonically vulnerable. But only recently, says Dr Paramesh Banerjee, have they been able to understand the full extent of the country’s seismic activity.
This new insight is made possible by the new Myanmar Seismic Network (MSN), established earlier this year. The network comprises 30 broadband seismometers, scattered throughout the country from the northernmost Kachin state, all the way to the Tenasserim Division in the south.
Dr Banerjee, Technical Director at the Earth Observatory of Singapore (EOS), led a team who built the network in collaboration with the Myanmar Earthquake Committee, and the Department of Meteorology and Hydrology in Myanmar.
The entire project took one year to complete–Dr Banerjee’s team began selecting possible sites to place the seismometers in July 2016, and the final seismometer station was constructed by July 2017.
At each of the 30 stations in the network, a high quality...

Inside Mount Mayon
Inside Mount Mayon
05 Oct 2017
As a Research Associate at the Earth Observatory of Singapore (EOS), a large part of my work concerns studying the gaseous emissions from Mount Mayon, in the Philippines. In collaboration with the Philippine Institute of Volcanology and Seismology (PHIVOLCS), we are working to identify the composition of the volcano’s plume, which can help us better understand what is going on beneath the surface.
Measuring gases in a volcanic plume is by no means straightforward. We can quantify the flux of sulphur dioxide via the permanent monitoring network at Mount Mayon, but to retrieve values for other volatiles such as carbon dioxide, water, and hydrogen sulfide, we must sample the plume directly. For this we use a Multi-Gas Analyzing System (MultiGAS) designed by Research Geologist Peter Kelly of the United States Geological Survey.
The infamously majestic Mayon however, provides its own set of challenges with its summit at 2,462 metres (m) above sea level, atop a...
