The 2011 Japanese tsunami set adrift tons of debris, some of it carrying live plants and animals that landed in North America more than a year later. It isn’t the first time species have traveled the globe on ersatz rafts, and it won’t be the last. But it is concerning.
Before it happened, it was hard to imagine that a combined megaquake and tsunami in Japan could cascade to a nuclear disaster. Yet that’s exactly what happened at the Fukushima Daiichi (Number 1) nuclear power plant, 220 kilometers northeast of Tokyo, last month. This incident has put Japan’s nuclear policy in the spotlight, but its implications go far beyond a single country.
The Fukushima Daiichi power plant located in the port town of Okuma in the Fukushima Prefecture, northeast Japan, has six boiling-water-type nuclear reactors supplied by General Electric (units 1, 2 and 3), Toshiba (units 3 and 5) and Hitachi (unit 4) for
A nuclear accident is defined by the International Atomic Energy Agency (IAEA) as an incident in which people died or property damage topped $50,000. In 1990, IAEA introduced the International Nuclear and Radiological Event Scale (INES) to rate and rank nuclear accidents. INES is a logarithmic scale that consists of seven levels: 0 (Deviation, no safety significance), 1 (Anomaly), 2 (Incident), 3 (Serious incident), 4 (Accident with local consequences), 5 (Accident with wider consequences), 6 (Serious accident) and 7 (Major accident).
August is shaping up to be a hazardous month for Asia — from the Andaman Islands in the Indian Ocean to Japan. In just the first half of the month, several earthquakes and two typhoons have struck the region. Here’s an update on these damaging events.
At 7:55 p.m. local time on Aug. 9, a magnitude-7.1 earthquake struck near Japan’s Izu Islands, 325 kilometers southwest of Tokyo. No death or damages have been reported.
Usually, when a major natural disaster strikes, a population becomes more alert and aware. People know what warning signs to watch for; they know what to do should such an event occur again. They increase their chances of staying alive. For example, intergenerational knowledge of tsunamis passed down by island tribes around the Indian Ocean is credited with saving lives during the 2004 Indian Ocean tsunami.
A powerful magnitude-8.9 earthquake struck near the eastern coast of Honshu, Japan, today at 2:46 p.m. local time. The quake sent a tsunami racing across the Pacific Ocean to Hawaii, making landfall just before 3 a.m. local time. The Pacific Tsunami Warning Center has more information.
