You Can Make a Difference

Your gift can create safer, more sustainable societies throughout Southeast Asia, while advancing critical knowledge through geohazard research. Find out about our work — and partner with us to make an impact.


Our Endowment fund recognises the long-term nature of the Observatory’s mandate: to protect the lives and livelihoods of millions of people vulnerable to geohazard risks across Southeast Asia.

Our commitment to supporting these efforts — now and in perpetuity — is the driving force behind this fund. Naming opportunities, legacy gifts, planned giving, and donations of every size can support the work of our educators and scientists, impact the connections we make among countries and communities, and offer the promise of a brighter future to students of diverse backgrounds, from Southeast Asia and beyond.

Your contribution can help form the foundation of a strong institution that advances science, scholarship, safety, and policy worldwide. You can give to teams tasked with researching specific geohazards, or help support work focused on a particular region. Unrestricted gifts are particularly valuable, providing the financial infrastructure needed to keep the Observatory growing.

In this endeavour, as in so many others, our donors are our partners.

Give to the Observatory Endowment and double your impact! Singapore believes in research and education, and will match your gift, multiplying the significance of your generosity and strengthening our ability to work together toward the common good.

Centre for Geohazard Observations

The powerful research we do lies in our capacity for collecting, assessing, and sharing data, and the Centre for Geohazard Observations is at the heart of these efforts.

The Centre manages the Observatory’s technical assets — from lab facilities and computing capabilities to field instrumentation and networks — and oversees the tools that help us monitor the geophysical environment.

Our GPS arrays improve systems that warn of impending tsunamis; seismic networks and sound-monitoring equipment detect earthquake and volcanic activity; ground-scanning LIDAR and earth-penetrating radar help us watch over hazardous conditions above and below the ground.

By helping support the Centre for Geohazard Observations, you can participate in our efforts to monitor geohazards throughout Southeast Asia, gathering valuable data, and sharing knowledge and expertise throughout the region.

Centre for Geohazard Communication and Education

The Centre for Geohazard Communication and Education bridges the gap between science and society.

Using outreach, education, workshops, and digital communications, the Centre disseminates information about new research, provides insight into geohazard crises, interacts with the media, and consults with business, government, and civic groups in dealing with the region’s unique environmental risks.

At all levels, these partnerships offer ways to integrate scientific understanding with local knowledge. By sharing experiences and expertise, expanding relationships with both scientific and nonscientific communities, and creating relationships with local and global partners, this group builds valuable awareness of natural hazards research.

Your gift to the Centre for Geohazard Communication and Education can help build strong ties between the work we do and the people we do it for.

Scholarships and Field Programmes

Supporting a student’s ability to explore the Earth’s dynamic processes can reap untold rewards.

Giving to our general scholarship fund, or creating your own named fund, is a philanthropic gift that can offer hope, change lives, and uplift future generations. By supporting scholarship programmes, donors remove some of the financial burden associated with a quality education, and allow promising students the opportunity to explore their potential to the fullest.

Field Programmes
Field studies provide an understanding of the Earth and environment that cannot be gained from classroom studies alone. Studies in the field give students the opportunity to connect concepts they’ve learned in the classroom with the real world, learn the cutting-edge techniques used in scientific research, and engage with the world around them.

Your financial assistance can help students emerge as professionals, dispersing across the region with the potential for implementing — or even creating — new tools and techniques aimed at safeguarding vulnerable populations, now and in the future.

The Climate Group

Our Climate Group focuses on the unique characteristics of Southeast Asia’s tropical environment.

Researchers study sea-level change, air quality, flooding, monsoons, tsunamis, marine environments, weather, and more, gathering much-needed data on climatic forces.

Working with scientists from around the region and beyond, the team monitors and measures characteristics of the environment, models conditions of the past, and develops new ways to deal with the future consequences of global climate change.

Your gift to this group will help us respond to emergent climate-related needs, establish norms for clean air and healthy marine environments, and create proactive ways of protecting both the people and the environment of Southeast Asia.

Hazards, Risk and Society

The Hazards, Risk, and Society Group explores the effects of geohazards on the rapidly growing population of Southeast Asia. As cities and settlements grow, so does the need for the team’s expertise.

Working intensively in the field, the Hazards, Risk, and Society group brings together scientists and civic leaders to share information and inform policy on controlling floods, building safe structures, maintaining clean air and water supplies, and creating effective sanitation systems.

By supporting this work, your gift can aid in the fight against the dangers presented by the region’s geohazards, and help rebuild lives after a disaster has struck.

The Tectonics Group

Over the years, some of the world’s biggest earthquakes have decimated areas of Southeast Asia and taken hundreds of lives. The Tectonics Group studies how and why, mapping webs of active faults hidden under the earth (and, in the case of tsunamis, under the water), and guarding against the dangers they present.

In their efforts to understand the region’s tectonic and seismic behavior, the Tectonics Group gathers information from both above and below ground, combining data from networks of high-tech sources — satellites, seismic stations, gravitational monitors — with information gathered in the field, where rocks and landforms hold clues to past events.

The knowledge gained, shared across the region, can pinpoint danger spots and alert growing communities to potential risks.

When you donate to Tectonics research, your gift supports EOS’s participation in international efforts to understand earthquakes and tsunamis. With your help, we can devise methods to improve forecasting and safeguard the growing populations of Southeast Asia.

The Volcano Group

The volcanoes of Southeast Asia are among the most active and destructive on Earth.

The Volcano Group is focused on understanding these enigmatic giants, their impact on the environment and society, and ways to mitigate the hazards they present.

Working with partners from across the globe, the Volcano Group maintains laboratories dedicated to monitoring the volcanoes of Southeast Asia, and conducts research aimed at producing the tools and techniques needed to forecast eruptions and safeguard communities.

Your gift to this group will help support critical research efforts, equipment needs, emergency response efforts, and the data collection and analysis programs needed to drive new leaps in understanding.

Eruption from Ili Lewotolok Volcano Recorded in Singapore

The activity of Ili Lewotolok (or Lewotolo) volcano ramped up on 29 November 2020 with a series of eruptions. The largest of these eruptions occurred at about 9:45am local/Singapore time (1:45am UTC) and sent a gas and ash plume more than 5 kilometres (km) into the atmosphere. This powerful eruption was recorded by the infrasound network from the Earth Observatory of Singapore (EOS).

Scientists from EOS use infrasound sensors to remotely characterise volcanic eruptions. Even if Ili Lewotolok volcano is about 2,500 km away from Singapore, the eruption on 29 November produced a clear infrasound signal on the Singapore Infrasound Array. The same array also successfully recorded the eruptions at Anak Krakatau in December 2018 and ...

Volcanic Soundscape: How Seismic Sounds Can Reveal Eruption Secrets

When a volcano erupts in the darkness of night, or when it is blanketed by clouds, determining even the most basic information about the plume can be very difficult. Particularly for air safety, information like the time the eruption started, the height of the plume, and the eruption duration are crucial for determining what air spaces will be impacted.

Published on 15 September 2020, in the Journal of Volcanology and Geothermal Research, is a study I led that developed a new method to estimate plume heights. This method utilises the long-travelling low-frequency sound waves produced by the eruptions.

Infrasound, or sound that falls below 20 Hz, can travel thousands of kilometers and carry with it information about an eruption. It’s truly fascinating because if you think about it, infrasound is just sound. The only difference is that humans can’t hear it. And yet within that...

How Singapore’s Geological Past May Save Us From the Rising Seas

Sea-level rise is a hot topic today in Singapore. Prime Minister Lee Hsien Loong, in his 2019 National Day Rally Speech, spoke at length about how vulnerable our island state is to 21st-century projections. However, sea-level rise is not a recent phenomenon and neither are the extreme impacts it has had on Singapore’s landscape.

Here’s another interesting fact – Singapore was not always an island. During past ‘ice ages’ where most of the world’s water was locked at the Poles, the sea was found hundreds of kilometres further away from where it is today. The clues pointing to what happened to Singapore thousands of years ago as a result of sea-level changes can be found right under our feet.

A team from NTU’s Earth Observatory of Singapore (EOS), the British Geological Survey (BGS), James Cook University (Cairns), and the Building and Construction Authority of Singapore (BCA) produced the first high-resolution 3D geological model for the Kallang River...

The Day Anak Krakatau Turned Deadly

On 22 December back in 2018, Indonesia’s Anak Krakatau volcano erupted. The collapse of its flank triggered a tsunami that killed more than 400 and injured at least 30,000 people. 

To understand how the events of that day unfolded with such catastrophic effect, an international research team led by Research Associate Anna Perttu from the Earth Observatory of Singapore (EOS) turned to the data collected from monitoring stations from all around the region, official reports, as well as satellite and visual observations.

Eruptions produce a wide range of signals. Humans can see and hear some of them only when close enough to the eruption. Monitoring instruments help fill the gap. Satellites can be used to image volcanic plumes that are too high or obstructed from an observer. And seismic and infrasound sensors are able to detect very small ground movements (e.g. earthquakes) and pressure waves (e.g. volcanic explosions).  

These waves can travel over very...

Using Large Earthquakes to Understand Singapore’s Underground Structure

The first results from Singapore’s first island-wide seismic survey unravel some important features of Singapore’s underground.

In March of last year, a team at the Earth Observatory of Singapore (EOS) recorded the ground movements of Singapore using 88 seismometers placed in locations such as schools, parks and weather stations.

We collected a vast quantity of fascinating data using distant earthquakes to image Singapore’s subsurface, and our first set of results were recently published in the journal Geophysical Research Letters.

Seismologists use a technique called receiver functions to look at boundaries between different rocks beneath our feet. The first seismic wave which arrives from a distant earthquake (the P wave) converts to another type of seismic wave (an S wave) at boundaries between rock types. This is known as a...

Rooting for a Solution to Sea-Level Rise

Rising from the muddy depths of Singapore’s tropical swamps, the distinctive roots of the mangrove trees lie draped in a descending curve – with some parts of the roots buried in the wet soil, and other parts exposed to the humid air. 

Because home along the coast is consistently flooded with sea water brought in by the tides, mangrove trees need to have a part of their roots above water to help them breathe in a waterlogged environment that is often low in oxygen. It is this distinct vertical accretion in their growth that makes mangrove trees incredibly important in our fight against climate change.

The mangrove ecosystem is an intriguing, intricate one that allows its trees to adapt to high temperature and salinity levels. As a dense forest, the tangled mangrove roots are instrumental in protecting our shorelines from erosion by strong winds, powerful waves, destructive storms and flooding. They effectively maintain our water’s quality and clarity...
