Japanese Scientists Find March 11th Earthquake was Cumulation of 6 Earthquakes – Possibility of another mega-quake bigger than any single event envisaged so far

The pattern of extensive strain accumulation on a tectonic plate before March 11 largely matched the actual fault slip that caused the Great East Japan Earthquake, a team of researchers said.

Based on records of known earthquakes before the March 11 disaster, it was believed that earthquakes of magnitude 7 to 8 occurred separately along different sections of the Japan Trench.

However, six earthquakes coincided and created the magnitude-9.0 mega-quake on March 11.

According to an analysis by the Geospatial Information Authority of Japan, strain accumulation is also distributed more extensively than any single hypothetical seismic source along the Nankai Trough, an underwater plate interface off the southern coast of Japan.

Following the Great East Japan Earthquake, attention is focused on the possibility of another mega-quake bigger than any single event envisaged so far.
