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 earthquake was so powerful it moved Honshu, Japanâs largest island, 2.4 metres east and shifted the Earth on its axis by an estimated 10 to 25 centimetres. Within the first day following the earthquake, more than 50 aftershocks were experienced, seven of which measured at least 6.3 on the Richter scale.
