Description :
Crack widths and rock temperatures were monitored on an andesitic bedrock cliff in the summit area of the Daisetsu Mountains, Hokkaido. Sequential data recorded the gradual widening of a crack to the point of critical crack extension, which resulted in catastrophic rock breakage. Using these sequential data, the timing, magnitude, and dominant agent of crack movement are considered, with particular focus on the parameters related to rock fracture mechanics.
