| Abstract: | Relative gravity measurements with CG-5 gravimeter were performed in the Kussharo Caldera area in 2022 and 2023. The measurement time at a gravity point was set to 90 min to decrease the effects from gravimeter transportation. It was found that the perturbation after 60 min to be less than 5 μGal and good for measurement. Data with tidal, drift and scale factor corrections represented stable gravity values less than 10 μGal changes at TOPT, KUTC, TNBT. The gravity increases of 80 μGal at S049 was not explained by volcanic inflation modeling and might be due to artificial reasons. |
