How EOS Contributed to COP26

A lot is at stake this year regarding what the climate holds for us in the future. The 26th United Nations Climate Change Conference of the Parties, more widely known as COP26, gathered world leaders to decide on climate actions that will shape our climate and its impacts on our societies. While scientists from the Earth Observatory of Singapore (EOS) could not join the physical event happening in Glasgow from 31 October to 12 November 2021, they have contributed in many other ways. Let’s find out how.

New EOS Study on the Dangers and Impacts of Unconfined Pyroclastic Flows

Volcanic eruptions are sometimes accompanied by clouds of ash and hot gases that travel down the slopes of volcanoes at tens of kilometres per hour. These clouds, called pyroclastic density currents (PDCs), are some of the deadliest volcanic hazards. And as we cannot easily study them in real-time, we took another approach to quantify some of the features that make them so dangerous: their speed, temperature, height, and how far they travelled.

2021 in Review

Dear EOS Community, 

Looking back on 2021 as Director of the Earth Observatory of Singapore (EOS), I am proud of EOS’ achievements as we adapted to numerous challenges associated with COVID-19, while focusing on critical research and producing impactful studies on geohazards and climate change. 

Unraveling Myanmar’s Underground Structure to Better Prepare for Future Geohazards

Lying at the junction of several tectonic plates, Myanmar is exposed to geohazards such as earthquakes, tsunamis, and volcanic eruptions. To help prepare for these hazards, scientists produce hazard assessments using their understanding of the region’s geology and tectonic activity. They seek to answer questions such as: how do the tectonic plates interact with each other, how deep the magma is, where the faults are, and what kinds of earthquakes can we expect? 

Exploring the Application of GPS for Climate Research

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.

The 1991 Eruption of Mount Pinatubo: The Biggest Ever Monitored

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).
