Tsunami in Japan

There was a big earthquake (8,9 on the Richter scale) about 1000km from here in Japan today, which led to a massive tsunami. Earthquakes are very common in Japan, but this was the biggest in the last 140 years. Everything is okay in Korea though, and I wish all the best for the people in Japan. An alert in a japanese nuclear power plant 800km from here sounds a bit scary.
