Leading an international study on the vulnerability of salt marshes in the United Kingdom (UK), scientists from the Earth Observatory of Singapore (EOS) at Nanyang Technological University warn that the enhanced rates in sea-level rise are likely to destroy the marshlands found in the UK sooner than previously thought.

Tidal wetlands in the contiguous US can store roughly 800 million tons of carbon in their soils. That is the latest estimate from a team of over 30 scientists, including Professor Benjamin Horton and Dr Tim Shaw from the Earth Observatory of Singapore and the Asian School of the Environment, published on 21 June 2018 in Nature Scientific Reports.

On 3 September 2017, the Democratic People’s Republic of Korea (North Korea) conducted its sixth underground nuclear test at the Punggye-ri test site. In collaboration with scientists from Germany, USA, and China, my colleagues from the Earth Observatory of Singapore (EOS) and I published our findings in Science on 11 May 2018, revealing the complex physical processes associated with the nuclear test.

Some eruptions are so large, and discharge so much magma (molten rock), that the roof of the magma chamber can no longer support itself. When the roof collapses, it forms a big hole in the ground called a caldera. One such volcano is Santorini, in Greece, whose distinctive ring shape was formed by multiple caldera collapses.

Earthquakes continue to cause tremendous damage and casualties around the world. Contrary to other geophysical hazards, such as storms and floods, seismic hazards still elude short-term prediction. This is due, on the one hand, to our limited understanding of how rocks deform and break; and on the other hand, by the difficulty of probing Earth's interior to determine the physical parameters of a given fault.

One year ago, scientists and science advocates from across the globe were moved to march in the streets.

Channel NewsAsia held a dialogue session on 24 January 2018 at the Funan Showsuite. Associate Professor Adam Switzer, a Principal Investigator at the Earth Observatory of Singapore, together with a panel of speakers, shared their thoughts on CNA’s INSIGHT episode, Fukushima — 6 years after the Daiichi disaster.

625 million people worldwide live in low elevation coastal zones (LECZ). By 2060, the LECZ population is likely to approach 1.4 billion people. These low-lying coastal regions, many of them in Southeast Asia (>70% of total LECZ population), are vulnerable to sea-level rise brought about by climate change.

The highly active Sumatran Subduction Zone has produced more than four great earthquakes in the last decade. The first of these was the giant Mw 9.2 Sumatra-Andaman earthquake that ruptured on 26 December 2004. This devastating event was followed by three others – the Mw 8.6 Nias-Simeulue quake in 2005, the Mw 8.4 Bengkulu earthquakes in 2007, and the Mw 7.7 Mentawai tsunami-earthquake in 2010.

In early 2016, the Earth Observatory of Singapore (EOS) installed a network of seismic stations in northeastern Bangladesh called TREMBLE - Temporary Receivers for Monitoring Bangladesh Earthquakes. The aim of TREMBLE is to monitor seismicity and study body waves - seismic waves that move through the earth’s interior. TREMBLE also enables shallow tomographic studies. It is an ongoing collaboration with Dhaka University’s Department of Geology.
