The Community Engagement Office aims to build the identity of the Observatory beyond the scientific community, reaching government and leadership, educators, partners, and the media. This is achieved by elevating our scientists’ research and expressing the importance of Earth science awareness through both local and international media, and through the Observatory’s social channels.

“Mw 6.6 Earthquake Strikes Off the Coast of Sumatra”

A strong earthquake struck the Nias region off the west coast of Sumatra, Indonesia, on 14 May 2021 at approximately 1:33pm (Singapore time). According to the United States Geological Survey (USGS), the magnitude-6.6 earthquake occurred at a depth of about 10 kilometres.

Based on information provided by the USGS, yesterday’s earthquake occurred within the Indo-Australian plate, where it bends before subducting under the Eurasian plate. As the plate bends, it can break and generate what is known as an outer-rise earthquake.

Yesterday’s earthquake is not a megathrust event as it did not occur at the boundary between the two tectonic plates, unlike the 2004 Great Sumatran earthquake. "It demonstrates how subduction zones are not just simple plate boundaries but involve internal deformation of both of the plates with complex seismicity," said Assistant Professor Judith Hubbard, a Principal Investigator at the Earth Observatory of Singapore (EOS) who studies...

“Why We Need to Reevaluate Earthquake and Tsunami Hazards Worldwide”

The magnitude-9 earthquake and associated tsunami that hit Japan in March 2011 illustrates the devastating power of earthquakes from subduction zones – boundaries where two tectonic plates converge, as one plate dives beneath the other. These are earthquake-prone regions that pose a threat to millions of people worldwide, especially in Southeast Asia. To help forecast such hazards, two new studies from the Earth Observatory of Singapore (EOS) investigated how these subduction zones work. The studies, published in Nature Geoscience, show that existing hazard assessments from subduction zones worldwide need to be updated.

Earthquake and tsunami assessments mostly rely on our knowledge of past events and of physical processes describing how one plate dives under the other at subduction zones. The more we know about these past events and physical processes, the more accurate the hazard assessments can be.

However, these assessments have so far mostly considered...

“The ‘Elysium Epic Trilogy’ Exhibition: Stories of a Changing Climate”

Visitors to the Earth Observatory of Singapore (EOS) will be familiar with the exhibition of polar and tropical marine wildlife by some of the world’s leading photographers.

The driving force behind the ‘Elysium Epic Trilogy’ exhibition is Mr Michael Aw, the entrepreneurial underwater photographer who organised three expeditions to the Arctic, Antarctic, and Coral Triangle to document the species featured in this unique exhibition.

The locations of three disparate Elysium expeditions share one common feature – they are all in the front line of climate change. Of his experiences in the Antarctic, the Arctic, and the Coral Triangle, Michael set the scene: “It is humbling and challenging because we can see what we will lose and how much or how little we can do about it, or at all, to slow down the effect of climate change. It is a really fast-changing environment.” 

Michael’s expedition team of scientists and artists travelled to the Antarctic in 2010. “...
