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.
Social media has found itself a heavyweight role in geology. By scraping Twitter and mining text data in Tweets, scientists at the Nanyang Technological University can now track where volcanic ash has fallen. This breakthrough won Assistant Professor Benoit Taisne and Professor Gao Cong the Accelerating Creativity and Excellence (ACE) Award for their research project titled “Detecting and Tracking Volcanic Ash Using Social Media Data”.
Have you got a poster presentation coming up and don’t know how to prepare for it ? We’ve got three award-winners here to help you – Ms Priyamvada Nanjundiah (Priya), Mr Yudha Setiawan Djamil, and Ms Regine Tiong Hui Yi.
I went to Banda Aceh, Indonesia in 2006 to help assess the impact of the 2004 Indian Ocean tsunami upon the region’s rich cultural heritage. The scale of destruction caused by the tsunami was staggering.
When the time came for us to choose a place to house the EOS Dynamic Earth Games, the answer was a clear and obvious one – the Science Centre Singapore (SCS).
When the Earth Observatory of Singapore (EOS) first decided to create educational materials about the earth sciences, all we knew then was that we wanted something extra fun, immersive, and highly interactive. The EOS Dynamic Earth Games that we have now were not yet in our minds.
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.
What makes up the exciting memories of my first interaction with science? I recall touching the slimy texture of snails, sniffing ammonia salt (also known as “smelly salt”), and making my sister’s hair stand with a balloon.
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.
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.
