Did my last blog post about the Dynamic Earth Games (DEG) leave you hungry for more details about the games? Well, I hope to satisfy your curiosity in this second post.

The Earth Observatory of Singapore (EOS) collaborated with BOHO Interactive and the Science Centre Singapore to develop seven different games. These fall into three broad categories:

Volcanoes and Typhoons

The Dynamic Earth Games explain the science behind natural hazards with a strong focus on geology and meteorology. While playing the games, you will learn some of the signs of an impending volcanic eruption and the tools that...

Soputan Volcano in north Sulawesi erupts five days after the neighbouring magnitude-7.5 Palu earthquake – Was the eruption triggered by the earthquake?

An eruption from Soputan volcano commenced at 08:47 local time on 3 October 2018, producing a dense ash plume that rose 4 kilometres (km) above the summit and drifted west and northwest. This event occurred five days after the magnitude-7.5 Palu earthquake that caused a disastrous tsunami. The epicentre was located at a depth of 10 km and about 600 km to the west-southwest of Soputan volcano.

Could the eruption have been triggered by the earthquake?

Earthquakes and volcanoes are intimately linked through plate tectonics. Examples of earthquake-volcano interactions namely include the 1975 eruption of Kīlauea...

The Singapore Series on Sea-Level Rise, a special blog series by four Masters students from the University of Melbourne.

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.

Although Singapore is not presently in a climate crisis, the effects are not far away. Other than extreme temperatures, one of...

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.

We found that the top of the mountain experienced a rise, collapse, and compaction at different time scales after the explosion. The explosive yield from the nuclear detonation with seismic and geodetic modeling was between 120-304 kilotons of TNT, which is more than 10 times the power...
