Channel NewsAsia’s documentary titled “Carbon Conundrum” investigates how carbon emissions contribute to rising global temperatures, which lead to rising sea levels and extreme weather events. In the documentary aired on television (channel 106 on Starhub) on 31 March 2020, Assistant Professor Aron Meltzner and his team provided insights on how rising sea levels in the southeast Asian region could impact Singapore.

Using microatolls (circular colonies of coral) the team is able to track changes in the sea level. A study led by Asst. Prof Meltzner found that more than 6,000 years ago when there was no human-driven climate change, there were fluctuations of about 60 centimetres in sea levels in southeast Asia. He...

EOS Principal Investigator Professor Kerry Sieh and his team has found what might be the location of the elusive impact site of a meteorite that struck Earth 790,000 years ago.

The impact was so large, debris from the strike was flung over three continents – Asia, Australia, and Antarctica. Yet, the location of the largest-known young meteorite impact site remained a mystery for a long time.

According to Prof Sieh, the Bolaven Volcanic Field in Southern Laos bears compelling characteristics that indicate it could be the location of this long-sought impact site.

To find out more, the published paper can be read in the Proceedings of the National Academy of Sciences of the United States...

Located high in the mountains are structures called “mountain huts” that provide refuge and safety to those who are in need of food and shelter. However, because of their location, these life-saving shelters are highly vulnerable to the projectiles from nearby erupting volcanoes.

In a study jointly conducted by scientists from the Earth Observatory of Singapore (EOS) and the University of Canterbury (UC), we looked at an eruption event in Japan to learn what we can about how to reduce the impacts of projectiles on roofs of building structures. Our findings were recently published on 7 November 2019 in the Journal of Volcanology and Geothermal Research.

We wanted to see...

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...

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...

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.

For me, science is a journey – a fun-filled adventure that satisfies our curiosity of the universe. Think about it. What makes us enjoy playing soccer, chess, or Candy Crush? Games are fun because they involve elements of competition with others, even ourselves, and some require us to cooperate with one or more people. This sense of competition and camaraderie are essentially what makes us enjoy playing games.

The Dynamic Earth Games, an Earth Observatory of Singapore (EOS) series of board games and card games about natural hazards, use these...

On 29 July 2018, Lombok was struck by a 6.4-magnitude earthquake, killing 20 people. A week later, an even stronger earthquake of magnitude 6.9 devasted the island. Strong aftershocks continued to rock the Indonesian island, quickly transforming the popular tourist paradise into “hell on earth”.

In an episode of Channel NewsAsia’s Insight titled "Lombok: A Shattered Paradise", aired on 7 September 2018, Prof Sieh provided insights on how tectonic plate movements could result in tsunamis, volcanic activities, as well as devastating earthquakes. Using the analogy of a cracked windshield on a car, Prof Sieh explained how aftershocks are produced from faults during an earthquake. In some instances, an aftershock can trigger a more powerful earthquake. This is possibly what...

On Sunday (29 July 2018), I learnt about the strong 6.4-magnitude (M) earthquake in Lombok, Indonesia. As we have friends living there, I wanted to visit to see what aid we could organise for the people there. So my husband and I went to Lombok with some friends, and we linked up with other humanitarian aid groups to visit the Sembalun area, which is about 1,000 metres above sea level, at the foothills of Mount Rinjani, one of the most scenic volcanoes in the world.

 

At about 6.46 pm the following Sunday (5 August 2018), just as we had finished a meeting to prioritise the relief needs, an earthquake suddenly occurred. It was my first time experiencing a quake, and it really shook the foundations of what I knew about them.

I realised I had many...
