Every year, millions of tourists travel to east Africa to watch millions of wildebeest, zebra, and other animals travel across the plains in one of the last “pristine” environments in world.
Professor Kerry Sieh choked up as he recalled picking up a small piece of mirror while an excavator tried to dig out 70 kids under a collapsed school at an earthquake site in Padang, Indonesia, in 2009. Experiencing the pain and grief of the locals in the aftermath of natural disasters, the dream of a young Kerry to make the world a safer place was never more appropriate.
We know human-induced climate change is real. It is happening across the world because of rising concentrations of greenhouse gas emissions in the atmosphere. Sometimes it is hard to know if the climate is changing if you are isolated from many of its effects. However, countless populations are already exposed to the impacts of climate change, which include: warming temperatures, changing rainfall, increased droughts and wildfires, decline in agricultural yield, more flooding, and many other consequences.
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).
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.
