- Findings by a Western-led international research team may mitigate hazard, damage, even loss of life by helping forecast the largest possible earthquake within a series of quakes, according to a study published today.
- From April 14-16, 2016, the Kumamoto, Japan, earthquakes featured a magnitude 7.3 mainshock two days after a magnitude 6.5 foreshock. The two quakes killed at least 50 people and injured 3,000 others. Severe damage occurred in Kumamoto and Ōita Prefectures, with numerous structures collapsing and catching fire. More than 44,000 people were evacuated from their homes due to the disaster.
- Researchers from Western, the Institute of Statistical Mathematics (Japan) and the University of Potsdam (Germany) studied those events and used them to create a new statistical approach that estimates the probabilities for such extreme earthquakes during a prolonged seismic sequence of events to be above certain magnitudes.
- The findings were published today in the journal Nature Communications.
- Historical data shows most earthquakes, like Kumamoto, occur unexpectedly and often trigger subsequent events far more powerful than the initial shock. Forecasting the largest expected earthquake within a series is critically important in mitigating hazard, damage and loss of life.
- Earth Sciences professor Robert Shcherbakov, first author on the study, stresses it is important to differentiate between forecasting and predicting earthquakes.
- The model, however, did allow Shcherbakov and his collaborators to estimate, retrospectively, the probabilities of having large subsequent earthquakes during several stages of the evolution of 2016 Kumamoto seismic event.
- A London teenager who as a high school student helped launched weekly “climate strikes” across the city is heading to New York to take part in the UN Youth Climate Summit.
- Before moving to Montreal to begin her first year at McGill University, Emma Lim, 18, stood outside London city hall or an MP’s office most Fridays to demand more action from governments to combat climate change.
- Lim began her weekly protest in January 2018 while she was a student at Banting secondary school. She also helped set up the first coalition of striking groups in Canada organized under the banner Fridays for Future.
- She is one of about 500 young people chosen to attend the first UN Climate Summit on Sept. 21. About 7,000 youth from around the world applied to attend the event at which youth will present their solutions to curb greenhouse gas emissions and talk with policy makers.
- She joined the international movement started by Greta Thunberg, a 16-year-old climate change activist from Sweden.
- Thunberg made headlines around the globe last month when she sailed to New York to attend the conference instead of flying that has a greater impact on the environment.
- Lim also spoke with and petitioned Justin Trudeau at his youth summit in May, protesting government leaders’ inaction on climate change.
- When Lim first started her Friday strikes she was alone, but eventually 30 to 50 students would join her for several hours. She also formed alliances with other regions.
- On Sept. 27, Lim will join several hundred thousand people — as well as Thunberg – in Montreal. Strikes will also take place in 200 cities across Canada.
- Lim will also be organizing 40 strike locations in Ontario, where 72 high schools have already registered for the walkout, and in northern Canada.
- Events will include acts of civil disobedience such sit-ins or” die-ins,” when protestors lie down and pretend they’re dead, and other events to raise public awareness about climate change.
- Bianca Andreescu makes history, to play Serena Williams in U.S. Open final
- 19-year-old becomes 1st Canadian to reach singles final in New York
- Down 2-5 in the second set, broken three times, exhausted and against the ropes, Andreescu won five straight games to defeat Switzerland's Belinda Bencic 7-6 (3), 7-5
- It sets up a brilliant U.S. Open final on Saturday, as Andreescu draws 23-time Grand Slam champion Serena Williams. Just last month, their Rogers Cup final matchup in Toronto ended abruptly when the 37-year-old Williams retired four games in due to a back injury.
