    The 7.1 mag earthquake was preceeded by a 7.0 earthquake also nearby.

    They are only 13 mi (32 km) apart and separated in time by 8 minutes. They are sufficiently shallow to cause tsunamis, but a lot depends on the degree of vertical motion of the sea floor, as opposed to lateral motion.

    They come two years to the day of the 9.1 mag earthquake off western Sumatra (Aceh), Indonesia.

    ...and you can imagine that today's anniversary was on everyone's minds as the quake hit.

    Earthquakes occur every day in different parts of the world.

    http://earthquake.usgs.gov/eqcenter/recenteqsanim/world.php [Broken] - provides the last 7 days by hour. It is purely coincidental that two major earthquakes just happen to follow Christmas this year, as was the 9.1 mag of Sumatra on Dec. 26, 2004.

    Looking at - http://earthquake.usgs.gov/regional/world/10_largest_world.php [Broken]

    7 of the 12 largest earthquakes in the world since 1900 occurred between the end of January to end of March. This is the time between Winter Solstice and Vernal Equinox in the norther hemisphere. Earth's perihelion with the sun occurs generally during the first week of January, and that should be the peak of the sun's gravitational (tidal) effect on the earth, and then there is the effect of the moon in conjunction with the sun.
