Japan conducts geological study in Antarctica

SHOWA BASE, Antarctica - Japan's 41st Antarctic expedition conducted a large-scale geological study in Antarctica by detonating dynamite in January to research underground structures. A total of 180 seismometers were buried deep under ice over a 200-kilometer-long area. Some 600-kilograms of dynamite were set at each of six points to cause an artificial earthquake of about magnitude 2. The photo, provided by expedition member Shintaro Nomoto, shows one of the explosions.
