In this interview series, we learn about the perspectives of the PhD students whose wide-ranging work contribute to the SEA2 Program and share what drives them in their research.

Underground sediments can serve as geological libraries that offer a glimpse into past environments such as bygone mangrove ecosystems and shorelines.

In a world largely driven by technology, the Global Positioning System (GPS) is ubiquitous. Best known for providing positioning, navigation, and timing services, the incorporation of this system into smartphones and smartwatches has made it almost indispensable for many.

Scientists at the Earth Observatory of Singapore (EOS) have explored the use of this system for climate research by observing the amount of water vapour in the atmosphere. Atmospheric water vapour, albeit invisible, plays a crucial role in shaping the Earth’s weather and climate.

In April 1991, the authorities in the Philippines began evacuating people from their homes located within 30 kilometres (km) of Mount Pinatubo. More than 60,000 people were evacuated by early June 1991. This huge undertaking came after recommendations from the Philippine Institute of Volcanology and Seismology (PHIVOLCS), and the US Geological Survey (USGS).

Did you know that the coral reefs of Southeast Asia account for a third of the world total? Spanning an area of 100,000 km2, these reefs are rich in biodiversity and provide critical services to coastal communities, including fisheries, tourism, and coastal protection.

The Himalayas rise and sink in a relentless cycle driven by geological forces. In an interview with National Geographic, Assistant Professor Judith Hubbard, a Principal Investigator at the Earth Observatory of Singapore, compares the evolution of the mountains to our breathing cycle.

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.

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.
