Shaking of seismic intensity 4 was confirmed in some areas of Chiba Prefecture.

Seismic intensity is a relative concept used by the Japan Meteorological Agency to indicate the degree of shaking felt by people or the extent of movement of surrounding objects in a given area, expressed on a scale from 0 to 7, unlike magnitude which represents the absolute strength. Intensity 4 means most people are startled, ceiling-hung lights shake, and unstable objects may fall.

NHK reported that there is no tsunami concern due to this earthquake.
