Five centuries ago, Leonardo da Vinci noticed fossilised sea creatures encrusted in the rocks around his house. He began to wonder whether, at some point, the mountains had been underwater. Da Vinci was right of course, but he would not be around to hear scientists explain why it was possible. Plate tectonics, now considered the unifying theory of geology, was born in 1968. Its birth was not easy and was spared no drama.

New research from the Earth Observatory of Singapore (EOS) recently published in Science introduces an exciting new technique for discerning the strength of rocks in the earth’s continental lower crust. The method we developed allows us to make inferences about the properties of rocks where they are buried. Our study also provides the first low-frequency tomographic image of rheological properties beneath Kyushu, Japan. Tomography allows us to see the internal properties of the rock, section by section.
It happened at 7:58am (Indonesian time) on 26 December 2004. In a few instants, the equivalent of 370 years of energy use in the United States, or 550 million times the power of the Hiroshima atomic bomb, was released off the west coast of Sumatra. While subducting beneath the Sunda Plate, the Indian Plate produced one of the deadliest natural disasters in recorded history.
The French Embassy in Jakarta was abuzz with excitement on Sunday, September 24 2017, as hundreds of people gathered together for the official launch of the second Marine Investigation of the Rupture Anatomy of the 2012 Great Earthquake (MIRAGE) expedition.
“We scientists usually think we know everything,” said Dr Wang Yu, a Research Fellow at the Earth Observatory of Singapore (EOS), “but when we go into the field, we start to realise that actually farmers have most of the important knowledge about the land, and that we are just visitors with lots to learn.”
"One of the things that first made me interested in geology was hearing about the number of places that geologists travel to for work." Tim Dawson, a Senior Engineering Geologist at California Geological Survey, reflects on the perks of being a geologist, and describes his most recent adventure in the trenches in northern Myanmar and Thailand during an earthquake geology training course.
In February 2017, scientists from the Earth Observatory of Singapore (EOS) led an earthquake geology training camp in Myanmar and Thailand. The course was designed to allow scientists to share their knowledge about active fault trenching and paleoseismology with geology students who may not have had prior field experience.
Bhutan was silently tucked away until it opened its borders merely 50 years ago, enthralling the world with novel ideas of happiness and sustainable living. By contrast, in just 50 years Singapore blossomed into a bustling metropolis, but still falters in terms of prioritising nature over economic progress.
The Singapore Eco Film Festival (SGEFF) is back for its second year, featuring 21 films from 14 countries. SGEFF is a space for people from the public, private, and creative sectors to come together to learn about pressing environmental challenges, and to share positive solutions to these issues.
