Mexico Launches National Tsunami Warning System
The Mexican government on Tuesday launched a national tsunami system to monitor quakes around the world that could impact the country’s coastline.
First-of-its-kind study reveals surprising ecological effects of earthquake and tsunami
The reappearance of long-forgotten habitats and the resurgence of species unseen for years may not be among the expected effects of a natural disaster. Yet that’s exactly what researchers have found on the sandy beaches of south central Chile, after an 8.8-magnitude earthquake and devastating tsunami in 2010. Their study also revealed a preview of the problems wrought by sea level rise, a major symptom of climate change.
Japan tsunami Debris Moves Towards US and Canada
The tsunami swept as much debris into the ocean in one day as is usually dumped in a year, threatening wildlife and the Pacific’s ecology. Washington, Oregon, British Columbia and Alaska should get much of the debris, while most of California might be protected by currents pushing objects back out to sea. Hawaii, however, is in line for several deposits of tsunami trash.
Japan Sea Sediments Tell of Past Tohoku Quakes
Previous earthquakes that rivalled the March 2011 Tohoku tremor in size may be recorded in sediment samples just recovered from the seafloor off Japan’s coast.
GPS Could Speed Up Tsunami Alerts
Global positioning systems (GPS) could provide faster tsunami alerts than current warning set-ups, German researchers said at the European Geosciences Union Conference in Vienna, citing data collected in last year’s deadly Japan earthquake.
Can Whales Predict Tsunamis?
As tsunami warnings hit the Indonesian and Sri Lankan coasts last week, observers at sea watched as every species of cetacean, from massive blue whales to diminutive spinner dolphins, vanished in the space of a few minutes.
Tsunami Watch Cancelled After 8.6-Magnitude Earthquake Off Indonesian Coast
Two powerful earthquakes struck more than 200 miles off the coast of the Indonesian island of Sumatra, but the tsunami watch was cancelled.
Radiation from Japan found in kelp off US West Coast
Radioactive iodine was found in kelp, sampled from coastal California, following last year’s earthquake-triggered Fukushima Daiichi nuclear meltdown, according to a new study.
Fukushima leak may have flowed into Pacific: TEPCO
About 12 tonnes of radioactive water has leaked at Japan’s crippled Fukushima Daiichi nuclear power plant, with the facility’s operator saying that some may have flowed into the Pacific Ocean.
