Although a number of seafloor samples will be cored towards the end of our four-week expedition, the main data-acquisition instruments aboard the research vessel Marion Dufresne are an echosounder and a sub-bottom profiler, both mounted on a gondola attached to the ship’s hull. These two instruments will produce the bathymetry that is so essential to the mission of the MIRAGE.
When a magnitude-8.6 earthquake struck the Wharton Basin on 11 April 2012, followed a few hours later by a M 8.2 shaker, it did not trigger devastating tsunamis.
Greetings from Colombo, Sri Lanka! My name is Ben Marks. I am the Communications Officer from the Earth Observatory of Singapore (EOS), and I will be your resident blogger for the next four weeks.
At a three-hour event on 28 June 2016, more than 40 representatives from partnering research institutes, ministries, embassies, and media outlets gathered at the headquarters of the Indonesian Institute of Sciences (LIPI) in central Jakarta.
The Indian Ocean basin has long fascinated geoscientists. Currently one of the most actively deforming oceanic basins in the world, it’s produced five great earthquakes in just the past ten years – ranging in magnitude from 8.2 to 9.2.
Sinabung volcano in Sumatra, Indonesia, has been almost continuously erupting in the last three years. It has been on the highest alert level since 2013.
A magnitude-6.2 earthquake occurred about 300 km southeast of Bali Island on 9 June 2016 at approximately 12.13pm (Singapore Time). Its epicentre is estimated to be close to the Java Trench front with a shallow focal depth from the global seismic network.
For Judith Hubbard, Principal Investigator of the structural geology group and Assistant Professor at the Asian School of the Environment, this was her very first radio interview ever. It was little wonder then that she was feeling slightly jittery. On the other hand, Professor Isaac Kerlow, Principal Investigator of the Art+Media Group at the Earth Observatory of Singapore, was the perfect picture of composure and confidence for he is quite the veteran at radio interviews and other media appearances.
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.
A magnitude-7.2 deep earthquake occurred offshore northeastern Taiwan on 31 May 2016. This is the second significant quake to have struck northern Taiwan this month, and it was powerful enough to generate strong ground motion throughout the whole of northern Taiwan.
