Free Planet doesn't normally DO earthquake swarms posts because they happen all the time, but one's going on RIGHT NOW off the east coast of Japan i.e. on the Fukushima side, that started in the far south of Japan in the range of 4.6 and above and has just started unleashing 5.6's and above off/around Sendai.
Here's a list this far today off of USGS's (so-called realtime) earthquake monitor:

4.7 57km NE of Yonakuni, Japan 2013-04-17 06:33:47 24.871°N 123.363°E 7.3
4.7 49km NE of Yonakuni, Japan 2013-04-17 05:57:58 24.852°N 123.405°E 10.0
as this post goes public, there's a NEW QUAKE at 6.0 magnitude leading some to speculate that THESE ARE JUST FORESHOCKS and another BIG ONE is brewing on that eastern coast where the 9.0 was so spectacularly devastating almost exactly two years ago.
This page shows earthquakes going off all over the eastern side of Japan, out at sea and inland almost all the time. Just wait until the greenish dots on that page turn to RED.
But this is one of the reasons Free Planet exists as an idea, so that mankind can a) free himself from the Corporate Yoke and b) be prepared for these catastrophic events that occur with regularity in this solar system.
APRIL 19TH UPDATE:
7.2 earthquake shakes northern Japan-USGS
11:39 am | Friday, April 19th, 2013
TOKYO–A major 7.2-magnitude earthquake struck off northern Japan on Friday, seismologists said, but no tsunami warning was issued. The quake hit at 0305 GMT near the Russian-administered Kuril island chain, 1,490 kilometres (926 miles) north of Tokyo, the US Geological Survey said. It was 122 km deep.
Not sure if this morning's 7.2M quake is THE BIG ONE this swarm hinted at but there are plenty of aftershocks going off every couple minutes in the 4.5+ range.
