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.

A New Way to Track Storm Surges

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.

Where on a Volcano is an Eruption Most Likely to Occur?

Magma commonly moves up towards the surface by creating cracks in the crust. It flows inside of the cracks, which grow upwards as the magma applies pressure and damages surrounding rocks. These magma-filled cracks are known as dikes and they are an important form which allows magma to travel easily through the crust.

The Child of Krakatoa Awakes

At approximately 9:30pm local time (2:30pm GMT) on the 22 December 2018, a tsunami struck Indonesia’s Sunda Strait, which lies between the islands of Java and Sumatra, claiming over 430 lives. According to Indonesia’s disaster agency there are at least 1,500 injured, over 120 people still missing, and around 12,000 people have been displaced.

Wrapping Up 2018

Dear EOS Community,

What a busy and exciting year for the Earth Observatory of Singapore (EOS). In early 2018, we kicked off the celebration of our 10thyear as a Research of Excellence at the Nanyang Techonological University (NTU). Marking a decade of geohazard research in Asia, EOS has built a team of outstanding scientists and staff to move the institution forward for years to come.
