Abundant evidence indicates that such a new volcano exists at L'ihi, a seamount (or submarine peak) located about 20 miles off the south coast.
In 2011, a 9.0-magnitude earthquake -- one of the worst ever to hit Japan -- killed more than 20,000 people and caused tsunamis of up to 12 meters (40 feet) which swamped the Fukushima Daiichi nuclear power plant, triggering a nuclear meltdown. Fukushima resident: We live in fear.
The most recent large earthquake of magnitude 9.0 or larger was a 9.0 magnitude earthquake in Japan in 2011 (as of March 2014), and it was the largest Japanese earthquake since records began.or instance, an earthquake of magnitude 6.0 releases approximately 30 times more energy than a 5.0 magnitude earthquake and a 7.0 magnitude earthquake releases 900 times (30 Ã 30) more energy than a 5.0 magnitude of earthquake.
