Abstract: An earthquake swarm begun on 25 July 2019 in mountain side of Nishi-ward, Sapporo city. The largest earthquake was the M3.1 on 1 August 2019. One temporal seismic station had been deployed in the focal region from 30 July 2019 to 27 September 2019. Hypocenter and velocity structure estimation was processed using the VELEST program. Hypocenters were distributed 1km wide in E-W direction and 6-8km deep, which was consistent with a nodal plane of focal mechanism.
