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.  

Singapore’s Prime Minister Lee Hsien Loong said in the 2019 National Day Rally speech that “climate change is one of the gravest challenges the human race faces and Singapore is already feeling its impact – which is likely to worsen over the next few decades”.

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. 

But what many do not know is that the thin layer of volcanic ash that had settled across Singapore could have been more severe. Typhoon Yunya (also known as Typhoon Diding) had struck the Philippines almost at the same time as the Mount Pinatubo eruption.

Previously, scientists had not investigated how the typhoon had affected the amount of ash that fell on Singapore. However, preliminary modelling results carried out by scientists at the Earth Observatory of Singapore (EOS) and Asian...

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.

Prof Horton felt that PM Lee had successfully communicated and emphasised the urgency for Singapore to take the right actions to deal with the effects of climate change. This is especially important for land-scarce Singapore, where we can’t simply move in-land as a means to adapt to sea levels that certainly will rise. As an important first step, he recommends that Singapore “invest in the science, [so that we] can have responsible and robust adaptation...

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.

But, after seven years, it’s time for a review. So over the past couple of years, we’ve been talking with our SCS colleagues about changing up the current exhibition to update the experience and story we’re telling. In November 2018, we pulled our third collaborator, the world-famous Exploratorium, into the mix and officially launched the redesign project with a plan to open...

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.

From this sequence of earthquakes, it is clear that the Mw 6.4 foreshock had triggered seismicity on conjugate faults (i.e. intersecting faults that criss-cross in a X-shape) along the Eastern California Shear Zone which runs somewhat parallel to the San Andreas Fault, but is...

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”.

Asst. Prof Taisne, a principal investigator at the Earth Observatory of Singapore (EOS), worked closely with...

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.

Priya, a PhD student at the Earth Observatory of Singapore (EOS), was one of the winners of the American Geophysical Union’s Outstanding Student Paper Awards in 2016. She also won Best Student Poster at 2017’s Asia Oceania Geosciences Society (AOGS). Yudha, also a...

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. Half the city had been pulverised and all that was left was a mix of concrete, broken furniture, household items, and a colorful patchwork of shreds of clothing. We found clusters of beautifully carved stone grave markers dating back centuries amongst the rubble, half buried in mud and debris, or piled up neglected near areas being cleared by NGOs and donors for new tracts of post-disaster housing.

The same waves that killed over 150,000 people and displaced millions had reached back into the past and threatened to wipe out the historical memories of Aceh’s coastal...

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).

SCS has an impressive 40-year record of making science fun and accessible to the public. They successfully reach out to and engage more than one million visitors annually.

We, at the Earth Observatory of Singapore (EOS), know just how capable the SCS team is. We have worked with them over the years on various projects and launches (e.g. “Earth: Our Untamed Planet” exhibit currently in SCS, and the film screening of EOS documentary The Ratu River). Most recently, we spent the past six months working closely with SCS and acclaimed Californian science museum, The Exploratorium, on a new earth science exhibition...

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.

The search for a team who could bring this to life for us was quite a task. That was until we met BOHO Interactive, a collective of artists and game designers from Australia.

During the planning phase, the BOHO team spent a good amount of time in EOS to learn about the different types of research being done by our scientists. They then shortlisted a few to build the games on. After developing several of these games, they tested the prototypes at different events with different audiences...
