Scientists at the Earth Observatory of Singapore (EOS) and Asian School of the Environment (ASE), at Nanyang Technological University (NTU), and collaborating institutions National University of Singapore and University of Colorado, have demonstrated the potential to use GPS (more generally known as GNSS) technology to track storm surges in coastal settings.

A new study, published on 5 March 2019 in leading journal GPS Solutions, reveals that GNSS signals can be used to track storm surges. Led by EOS Research Fellow, Dr Dongju Peng, the work was supported by a Ministry of Education grant to...

A one-metre rise in sea level could dramatically increase the frequency of flooding up to almost five times for tsunami-safe Macau, in a new study led by scientists from Nanyang Technological University, Singapore (NTU Singapore). 

The team of scientists from NTU’s Earth Observatory of Singapore (EOS) and Asian School of the Environment (ASE), used computer modelling, and initially showed that Macau, a densely populated coastal city in China, is relatively safe from tsunamis as it requires an earthquake larger than 8.8-magnitude to cause widespread tsunami floods.

However, with just a sea level rise of 0.5 metres, the tsunami-induced flood risk increases to up to 2.4 times and with a 1 metre rise, up to 4.7 times. 

The increased flooding frequency was...
