At 2 PM, on 7th December 1828, a major earthquake occurred at Kanagawa post town, in Yokohama city. In the present study, using historical documents describing this event, we obtain a detailed map of the distribution of seismic intensity. It is clarified that the area of seismic intensity 6 to 7 (JMA scale) covers the main areas of Yokohama city. The area of intensity 5 covers whole part of Tokyo city zone, the eastern part of Kanagawa prefecture. The magnitude of this event was estimated at 6.4 using the area of intensity 5.
