As previously shown many times on the geoblogosphere, the USGS's earthquake site is a good site for recent and occurring earthquakes. While looking through the site I saw on November 24, 2008 at 09:02 UTC, a 7.3 magnitude quake happened in the Sea of Okhotsk, off the west coast of Kamchatka. Under the "seismic cross section" there is a great map illustrating the variation in quake depth at subduction zones. The November 24 quake was deep focus at a depth of 491 km, well into the Wadati-Benioff zone. The map shows the increasing depth of foci from the boundary, as the subducting plate moves deeper into the mantle.
