In the early morning at about 5am on 12 February 2020, a bright object was seen in the sky. It blazed over Singapore and Johor Bahru, Malaysia, and its lights were caught on two dash-cam videos. The video that was filmed in Singapore was captured near the Nanyang Technological University campus, next to the Jalan Bahar flyover.

When an object enters the Earth’s atmosphere and burns up on entry, the way we name it depends on how big it is, as well as how bright. For example, an asteroid is a piece of rocky, iron, or icy debris, over...

A new study from the Earth Observatory of Singapore (EOS) sheds new light on the 2015 Sabah earthquake. Published on 9 March 2017 in Geoscience Letters, the research paper provides a complete analysis of the quake and explains how it triggered the deadly landslides that killed seven children. It also finds that the fault system responsible for the quake has the potential to produce a magnitude-7.0 rupture, or larger, in the future. 

The magnitude-6.0 earthquake in Sabah was devastating mostly because it triggered landslides on Mount Kinabalu, the highest mountain standing in Southeast Asia. The landslides killed 18 hikers and injured at least 21 more.

The quake came...

Edible vegetable oil, produced from oil palm and soybeans, is a key ingredient in junk food like chips and ice cream. Although these foods have little to no nutritional value, global consumption is on the rise, resulting in an increase in demand for vegetable oil. This has become a serious issue because large areas of land in Southeast Asia and South America have to be cleared to make way for oil palm and soybean crops. 

A study, led by Assistant Professor Janice Lee of the Asian School of the Environment, has found that more forests will be cleared by the year 2050 as a result of the increased demand in vegetable oil. Along with this deforestation, valuable biodiversity will be lost in Southeast Asia, and sequestered carbon (carbon stored in plants, soils, and geologic...

Last year, a magnitude-6.0 earthquake rocked the Sabah region of Malaysia. The quake triggered massive rock avalanches on Mount Kinabalu and tragically took the lives of 18 people on the mountain. It included the lives of seven primary school students from Singapore who were on a field trip during their school holidays.

After the earthquake, Dr Wang Yu, a Research Fellow from the Earth Observatory of Singapore (EOS), visited Sabah for a quick post-earthquake survey. There, he found buildings with cracked foundations, caved-in ceilings, and broken pillars that result from the strong ground-shaking motions. The heavy rains that followed after the earthquake caused debris flow, further damaging the area’s bridges and buildings. In total, the quake caused almost S$35 million...
