This resource provides an abstract. Seventeen years of shockwave recordings were used to investigate crack healing after the large March 1997 Tokai region earthquake in Japan. Recordings taken at two stations in Japan from 1986 to 1996 were of shockwaves generated by other earthquakes, which passed through the crust region damaged by the 1997 Tokai quake. Comparing the observations taken before the earthquake to those taken afterwards, the researchers determined that the cracks healed in about two years, a finding similar to that of previous studies of crack repair.
