The devastating 2011 Tohoku earthquake in northeastern Japan was a record-breaker on many levels. The magnitude-9.0 quake was Japan’s largest recorded and the world’s fourth biggest earthquake since 1900. Most terribly, it unleashed a 39-metre high tsunami, killing almost 16,000 people and causing a nuclear meltdown at Fukushima Daiichi Nuclear Power Plant.
Results from the MEGA-TERA expedition point to a new fault system that may be a sign of the Indian and Australian plates breaking up.
Every year, the American Geophysical Union (AGU) hands out several Outstanding Student Paper Awards (OSPAs) as a way to honour young scientists at the beginning of their careers for quality research in the geophysical sciences. These awards are given to the top 3-5% of presenters in each section/focus group at the annual AGU Fall Meeting.
Last December, a big contingent from the Earth Observatory of Singapore (EOS) travelled to the American Geophysical Union (AGU) conference, the largest gathering of earth and space scientists in the world. Around 24,000 people descended upon San Francisco to catch up with colleagues, present their research, and learn about the latest advancements in their fields.
In March, we kicked off the EOS Institutional Blog. Our goal – create a space for you to learn more about what our scientists and teams are up to. As I look back on the stories we shared covering new research, current hazardous activity in the region, and outreach events, I’m thrilled to have the Institutional Blog as a reminder of the great work we’ve done and the fruitful year we’ve had.
At just past five o'clock in the morning on 7 December 2016, a damaging earthquake struck Aceh, Indonesia. Damage was most severe in Pidie Jaya and neighbouring Pidie and Biruen Regencies, located east of the provincial capital of Banda Aceh. Extensive building damage tragically led to the loss of more than 100 lives. More than 80,000 people are displaced, unable to return because of destroyed or damaged buildings.
The previous post focused mainly on the 1991 Pinatubo eruption and how it affected humans and history (scientific in this case). Today’s post will cover a historic eruption that changed the course of history on one Indonesian island, and around the world.
Humans are fabulous agents of geologic change. What do I mean by this? We reduce the height of mountains via mountaintop mining to obtain energy resources. We blast through a mountain to make a road cut, or tunnel. We make new lakes by building dams for hydroelectric power. Indeed, we humans are capable of changing the landscape or environment (or climate for that matter) at rates much faster than normal geologic processes.
Several people who felt the 7.8-magnitude earthquake that hit New Zealand earlier this month also witnessed a strange phenomenon — lights flashing across the sky in a range of colours.
In the night of 21 November 2016 (local time), Japan was struck by a magnitude-6.9 earthquake. This was soon followed by a M 5.6 quake in New Zealand’s North Island, which sparked speculation that the event in Japan had triggered the one in New Zealand.
