In case you haven't heard, a spate of earthquakes have hit the Sumatra region of Indonesia in the last 24 hours - more than 60 of them according to CNN. For the scientifically/geographically minded, here's a map of the region from the USGS in which color indicates how recent the quake was (red is most recent), and size of the box indicates magnitude. It's a little nuts how many of the >7 boxes there are.

FWIW, the biggest nuclear bomb ever exploded had as much energy as a 7th magnitude quake, and ever additional magnitude is more than 30 times more energy.

No significant tsunami as of yet thankfully - a 0.6m (2ft) one was confirmed yesterday, and there's rumors of a 1-3m (3-9ft) one but unconfirmed.
