Photographs of mud and debris flows. See Fig. 2 for shooting locations. a Lahar flowing down Stream L in Owakudani (15:56 of June 29). b A flow channel downstream of a. Note that mud deposits are wider than that of the stream width at that time, which implies a higher flux of mud flow in the early phase of the eruption (15:09 of June 29). c Eruption center during the eruption (17:29 of June 29). Debris flow deposit had been emplaced. d Debris flow deposits near no. 55 SPW (9:10 of July 10). Note that the stream across the debris flow deposit (Stream L) is colored gray, even 9 days after the eruption. Large rocks on the left bank and right of the scale were set before eruption by the company to protect no. 55 SPW. All photographs were taken by HSRI
