How a Volcano Influenced Earthquakes in Lombok, Indonesia

A series of deadly earthquakes struck the Indonesian island of Lombok over three weeks in August 2018, causing widespread damage. These earthquakes were unusual because there were two magnitude-6.9 mainshock events that were each preceded by a smaller foreshock, instead of a single mainshock. The complexity of the earthquake sequence caused great anxiety about when another powerful earthquake might occur.

2020: A Year at EOS in Review

Dear EOS Community,

This year has been an extraordinary one and has been challenging for many, but it has demonstrated how resilient and innovative we can be in response to unique circumstances during this “new normal”. We continued addressing critical questions in Earth science, conducted more research in Singapore than ever before, and brought our science to the public with two exhibitions and a documentary series in collaboration with our partners.

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).

Why Back-to-Back Typhoons are Common for Southeast Asia

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.
