In conversation with Dr Karen Lythgoe, Research Fellow at the Earth Observatory of Singapore

1. What area of earth science do you study and monitor?

I am a seismologist at the Earth Observatory of Singapore at Nanyang Technological University, where I monitor and study earthquake hazards and sub-surface imaging both for the deep and the shallow earth. I apply seismology to important Earth science problems, including earthquake processes, Earth structure and dynamics, and smart city development.

2. What opportunities exist to capture heat from the deep earth to create low carbon energy and reduce the emission of greenhouse gases?

Typhoon Goni (Rolly in the Philippines) caused more than 20 fatalities in the Philippines earlier this month. Just a few days later, Typhoon Vamco (Ulysses) struck the Philippines again, then Vietnam on the other side of the South China Sea. “It is fairly common for more than one storm to occur in an ocean basin at the same time”, said Associate Professor Adam Switzer, a Principal Investigator at the Earth Observatory of Singapore. “Since typhoon season in Asia runs into the new year, there is unfortunately a real chance of further storms in the region before the end of 2020”, Assoc Prof Switzer added.

Typhoons form under specific sets of conditions between the ocean and the atmosphere. For example, warm sea...

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...

Pandemics & Natural Hazards is a special series for the EOS Blog which looks at the compounding impacts of coinciding disasters. This third commentary is a contribution from EOS’ Centre for Geohazard Observations.

The daily coverage of the novel coronavirus disease (COVID-19) in the media has given the public an insight into how the crisis has impacted the healthcare sector. We’ve seen footage of hospitals inundated with stricken patients, hospital staff begging for supplies, and the global race to find the medical holy grail of the moment – a COVID-19 vaccine.

But what about the other sectors of science that are not directly linked to the coronavirus? How are they coping with, even transforming in, this pandemic and the ensuing cross-border lockdowns?
