I was part of a team who recently went to Myanmar to repair instruments that are key to understanding natural hazards in the region. We worked and stayed with the locals the whole time, which was an amazing way to discover the Myanmar culture.

Singapore, unlike Japan, does not have any volcanoes. However, our little sunny island is in proximity to 127 active volcanoes in Indonesia and 53 in the Philippines. This means that both Singapore and Japan could be significantly affected by different types of volcanic hazards, making research on volcanoes an important area of study for both countries. Here’s why.

Located high in the mountains are structures called “mountain huts” that provide refuge and safety to those who are in need of food and shelter. However, because of their location, these life-saving shelters are highly vulnerable to the projectiles from nearby erupting volcanoes.

At home and abroad there is increasing agreement that we are facing an existential environmental crisis. Death, destruction, and disruption by extreme weather events, haze from forest fires, and contamination of oceans by plastic waste have dramatically increased the awareness of environmental degradation, and given rise to a realisation that the conclusions from decades of scientific research, and the dire predictions arising from it, indeed point to a considerable challenge to society.
