The History of the World's Climate Captured in a Snail’s Shell

When the world’s climate changes in significant or unexpected ways, these anomalies impact different regions in a dissimilar manner. During the last Little Ice Age between 1500 and 1850 AD, for example, the Western Himalayas experienced surprisingly warmer spring temperatures while the northern latitudes were covered in more snow than usual.

Singapore Teams Up with Japan to Tackle Volcano Problems

Singapore, unlike Japan, does not have any volcanoes. However, our little sunny island is in proximity to 127 active volcanoes in Indonesia and 53 in the Philippines. This means that both Singapore and Japan could be significantly affected by different types of volcanic hazards, making research on volcanoes an important area of study for both countries. Here’s why.

How We Can All Live in Harmony with Life on Earth

At home and abroad there is increasing agreement that we are facing an existential environmental crisis. Death, destruction, and disruption by extreme weather events, haze from forest fires, and contamination of oceans by plastic waste have dramatically increased the awareness of environmental degradation, and given rise to a realisation that the conclusions from decades of scientific research, and the dire predictions arising from it, indeed point to a considerable challenge to society.  

Powerful Twin Quakes Strike Southern California

On 5 July 2019 at 1.33am (Singapore time), a Mw 6.4 earthquake struck the town of Ridgecrest in California. Its seismic waves could be felt from Los Angeles to San Jose. Nearly a day and a half later, on 6 July at 11.19am (Singapore time), a more powerful Mw 7.1 quake struck the same region. Because the Mw 7.1 earthquake is the largest event so far in this sequence, it is considered to be the mainshock. The events leading up to it, which include the Mw 6.4 quake, are considered to be foreshocks.

Seis-ing Up Singapore

What lies beneath Singapore?

With land in scarce supply, Singapore is increasingly looking underground for storage spaces and even city construction. A team from the Earth Observatory of Singapore (EOS) have started working on a seismic survey to find out more about Singapore’s underground seismic structure and seismic hazard.
