Subduction zones are the most violent collisions on Earth. They are so powerful that even scientists who are familiar with the dynamics of plate tectonics are humbled by images of the aftermath.

As a Research Associate at the Earth Observatory of Singapore (EOS), a large part of my work concerns studying the gaseous emissions from Mount Mayon, in the Philippines. In collaboration with the Philippine Institute of Volcanology and Seismology (PHIVOLCS), we are working to identify the composition of the volcano’s plume, which can help us better understand what is going on beneath the surface.

One week into the MIRAGE II expedition, the Marion Dufresne French research vessel is navigating its way to the Wharton Basin in the northeast corner of the Indian Ocean. Marion Dufresne is 120 metres long and weighs more than 10,000 tonnes when fully loaded. There are 59 cabins on board, as well as a hospital, pharmacy, conference centre, library, dining room, gym, and more.

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.
