The overarching goal of our studies is to characterise the strength of the lithosphere from geodetic to geologic time-scales and explore its implications for landscape evolution and mantle dynamics. The strength of the lithosphere allows for the support of high topography in the Tibetan Plateau... Read more
We plan a reconstruction of late Quaternary environmental history of the Kallang basin, southern Singapore. Our research integrates sedimentary facies analysis, unique scanning technologies, a chronological framework from radiocarbon and OSL dating, and geochemical investigations of δ13C, δ15N,...

We plan a comparative study to test the feasibility of reconstructing hydroclimate and temperature variability during the past (MIS 5e) and current (Holocene) interglacials from marine sediment cores recovered offshore from Singapore. We will analyse the stable isotopes (d18O and d13C) and trace... Read more
We propose using geomicrobiology to overcome the primary issue in documenting prehistorical coastal hazards which is the faint distinction between storm and tsunami deposited sediments. In 2017, we completed our study in Phra Thong Island, Thailand that shows that microbial community analysis... Read more

To assess disaster risk more precisely, Switzer and his group are looking for microbial signatures that indicate past coastal flooding.
Since sea level rise isn't uniform globally, Switzer is using coral reef data from corals to develop a model for how well corals record sea levels and to determine historical sea levels during the Sunda Islands in Indonesia.
As the ice caps rapidly melt and lead to rising sea levels, there’s a renewed interest in similar melting events from the past. Singapore is an excellent place to study sea-level rise over the past 10,000 years. The city centre lies on Quaternary sediments that have previously yielded high-... Read more
This project will be conducting fieldwork in Malaysia to study sea level change throughout the past 8,000 years.
The project, funded by the Australian Research Council (ARC), aims to provide a new understanding of Indo-Pacific history post-1000 C.E. based on an enhanced understanding of the inter-relationship between natural environmental cycles and events, and social and political cycles and events. By... Read more
This study aims to identify potential historical tsunami deposits on the southern coast of Java and to determine if local historical records can provide valuable information for the discovery of past tsunamis.
Switzer and his team are studying the chemistry of ostracods, tiny shrimp-like creatures that are common in the fossil record, to see if they can be useful for quantifying past environmental and climate change.
This pilot project presents the initial phase of a potential long-term project to investigate the nature and timing of Holocene uplift events in Northwest Luzon, Philippines. Such a record will help in characterising the nature and periodicity of large seismic events on the subduction megathrust... Read more
In the 2nd year of this study, we aim to reconstruct the impacts of the 1897 (Ty1897) typhoon in Tacloban, Philippines using a combination of geological/geomorphological evidence, historical records and computer modelling. Our initial work implies that although both Haiyan and Ty1897 were of... Read more
Estimating the probability of tsunami occurrence is fundamental to tsunami flooding risk assessments in the South China Sea. It provides baseline information for setting construction standards and planning risk mitigation efforts. In this joint Coastal Lab/Applied Project Group project, we are... Read more
Asia is a fast growing economic region and most of the industrial and economy activities focus along the coastline of Asia. This coastline of Asia is prone to typhoon hazards that inflict significant damage and loss of life to the coastal communities. Regional governments, private... Read more
The coastline of Laoag has been affected by tectonic uplift at various times, resulting in stranded historic shorelines and dune systems. This project will use a combination of Ground Penetrating Radar (GPR) and OSL dating to gauge the amount and determine the timing of uplift for the area.
Noting that Guy Carpenter (GC) and its clients have considerable exposure to coastal hazards in Southeast Asia, GC, in conjunction with EOS, sought to produce a map that used historic and prehistoric events to highlight the vulnerability of Southeast Asia’s coast to tropical cyclones, tsunamis...
