“When would be the next eruption?” is a recurring question posed to volcanologists. And it is a challenging one to answer as many processes over different timescales are at play before an eruption.
Channel NewsAsia’s documentary titled “Carbon Conundrum” investigates how carbon emissions contribute to rising global temperatures, which lead to rising sea levels and extreme weather events. In the documentary aired on television (channel 106 on Starhub) on 31 March 2020, Assistant Professor Aron Meltzner and his team provided insights on how rising sea levels in the southeast Asian region could impact Singapore.
113 years ago, on 4 January 1907, a powerful magnitude (M) 8.2-8.4 earthquake occurred off the west coast of Sumatra, Indonesia. This earthquake belonged to a special class called “tsunami earthquakes” that do not generate very strong shaking, but can result in large tsunamis.
When the world’s climate changes in significant or unexpected ways, these anomalies impact different regions in a dissimilar manner. During the last Little Ice Age between 1500 and 1850 AD, for example, the Western Himalayas experienced surprisingly warmer spring temperatures while the northern latitudes were covered in more snow than usual.
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.
As at 5 pm on 15 January 2020, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) reported that Taal volcano’s eruption is still going on and retained the Alert Level for Taal at 4 (hazardous eruption imminent), where further eruptions are likely to occur in the coming hours or days.
As at 1 pm on 14 January 2020, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) retained the Alert Level for Taal volcano at 4 (hazardous eruption imminent), which means that further eruptions are likely in the coming hours or days.
A continuous eruption from Philippines’ Taal volcano was observed on Sunday, 12 January 2020, at 5.30 pm (Singapore time). The powerful eruption sent an ash plume 10-15 kilometres (km) into the atmosphere and ashfall as far as Quezon city 65 km away, with volcanic lightning seen flickering continuously in the plume above the volcano.
Urban flooding is an increasingly urgent problem affecting cities in Southeast Asia. In addition to being urgent, flooding is also deeply complex — the causes and consequences of floods are varied and often combine historical, political, environmental and economic factors in unique ways.
EOS Principal Investigator Professor Kerry Sieh and his team has found what might be the location of the elusive impact site of a meteorite that struck Earth 790,000 years ago.
