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...

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.

The Earth Observatory of Singapore (EOS) collaborated with BOHO Interactive and the Science Centre Singapore to develop seven different games. These fall into three broad categories:

Volcanoes and Typhoons, Assessing Risk, and Evacuation.

Volcanoes and Typhoons

The Dynamic Earth Games explain the science behind natural hazards with a strong focus on geology and meteorology. While playing the games, you will learn some of the signs of an impending volcanic eruption and the tools that...

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...

At approximately 9:30pm local time (2:30pm GMT) on the 22nd 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.

The tsunami occurred during a local holiday for the December solstice, striking a number of popular tourist destinations, including the Tanjung Lesung beach resort in the west of Java. Eyewitness reports indicate there were two separate waves, with the second, larger wave causing the most damage. 

The tsunami was caused by a violent eruption of Anak Krakatau (Fig. 1), the "child" of Krakatoa, in the Sunda Strait....

On 28 September 2018, central Sulawesi in Indonesia got struck by a powerful earthquake measuring 7.5 in magnitude (M). A tsunami that followed later devastated the city of Palu and the town of Donggala, leaving more than a thousand dead and even more homeless.

Associate Professor Adam Switzer, a Principal Investigator at the Earth Observatory, shares with us why this earthquake-tsunami event is a complicated one and what you can do to stay as safe as possible if you were ever caught up in one.

The Singapore Series on Sea-Level Rise, a special blog series by four Masters students from the University of Melbourne.

We know human-induced climate change is real. It is happening across the world because of rising concentrations of greenhouse gas emissions in the atmosphere.

Sometimes it is hard to know if the climate is changing if you are isolated from many of its effects. However, countless populations are already exposed to the impacts of climate change, which include: warming temperatures, changing rainfall, increased droughts and wildfires, decline in agricultural yield, more flooding, and many other consequences.

Although Singapore is not presently in a climate crisis, the effects are not far away. Other than extreme temperatures, one of...

Dear EOS Community,

As the year comes to a close, I’d like to thank you for your continued interest and support in the research, initiatives and programs being conducted here at the Earth Observatory. Over the past year, your increased engagement has helped us to better understand your interests in geohazard research and provide content to meet them. From publications to awards and new blog series, here is a look back on a few highlights from 2017.

As data from the Mentawai Earthquake Gap—Tsunami Earthquake Risk Assessment (MEGA-TERA) marine expedition carried out in 2015 was being analysed and while new data from the Marine Investigation of the Rupture Anatomy of the 2012 Great Earthquake (MIRAGE) expedition was being collected in 2016, we were already planning a third...

Different rainforest trees grow on an island called Siberut; one of four big islands of the Mentawai Archipelago located off the west coast of Sumatra, Indonesia. Katuka is what Mentawaians call one family of these dipterocarp trees. These trees have very hard wood and are widely used for construction and crafting.

I want to tell you the story of one katuka tree in particular. This 400-year-old tree will soon surrender its life to serve the needs of the people. 

A Giant Falls

As the sun rises over Siberut Island, a Mentawaian called Aman Ani and his fellow villagers sharpen their axes. They prepare their meals, as well as an offering for the forest spirits. Later, they sit quietly in a motorised canoe as they cruise upstream. Some of them are...

Sinabung volcano in Sumatra, Indonesia, has been almost continuously erupting in the last three years. It has been on the highest alert level since 2013. 

Most of the eruptions on Mount Sinabung have been small. These eruptions vary between lava flows and dome extrusions that accumulate on the volcanic crater, and include explosions with ash plumes that are lower than 3 kilometres (km) in height.

The most common activity on the volcano are the pyroclastic flows that are generated by the gravitational collapse of the dome rocks that have gathered on the summit. The travel distance of these pyroclastic flows range from 2 km to 5 km. As such, since 2014, the exclusion zones were appropriately implemented up to 7 km of the south (S) sector and 6 km southeast-east (SE-E) of...
