Well, I've been going off-topic too much lately so here is an earthquake post.
There was a M6 quake in Lake Kivu, near the volcanos in the West Branch of the East African Rift System. My advisor for my DEA geology degree at University of Paris published that faulting along this branch included a strong component of right-lateral strike-slip, and that some of the volcanos were located in "pull-aparts" where extension was enhanced. There is a large normal-slip component: this is a rift after all. There is no focal mechanism posted on this one yet.

Academic researchers funded by Elf Acquitaine (French oil company) acquired high-quality seismic reflection data from a catamaran sailboat. We drove south down the paved road from Bujumbura Burundi to deliver supplies to the catamaran. Paddled out in a little rubber boat and had a drink on the boat. We later took our vehicle on the Lake Tanginyika ferry, which was brought in in pieces by train and assembled in 1914 or so. It took several days to get to the south end...these are really big lakes...and slow ferrys. Some of the stops were off of beaches and people loading came out in dugout canoes.
