During the early evening of 28 September 2018, a magnitude-7.5 earthquake struck along the coast of northwestern Sulawesi, Indonesia. This region hosts a famous strike-slip fault system called the Palu-Koro Fault.
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.
Many may still remember the powerful eruption of Mount Pinatubo in 1991. It was one of the largest eruptions in recent history, and sent volcanic ash even as far as Singapore, over 2,400 kilometres (km) away.
In the video below, Professor Benjamin Horton, Principal Investigator at the Earth Observatory of Singapore and Chair of the Asian School of the Environment, shares his thoughts on the topic of climate and sea-level rise in Prime Minister Lee Hsien Loong’s 2019 National Day Rally (NDR) speech that was aired on 18 August 2019.
Since 2012, EOS has had a presence at the Science Centre Singapore (SCS), with 'Earth: Our Untamed Planet' exhibition. Through this parternship, EOS and SCS have welcomed millions of Singapore students and visitors from around the world to the exhibition, providing research, stories, and experiences that shape the geological framework of Southeast Asia, and the many natural hazards facing the region.
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).
