The earthquake caused a maximum seismic intensity of 5-strong (5-ky?) in Kisarazu City, southern Chiba Prefecture. In the same prefecture, Katsuura City experienced a seismic intensity of 5-weak (5-jaku), and most other areas within the prefecture felt a seismic intensity of 4.

The seismic intensity scale used by the Japan Meteorological Agency differs from magnitude, which measures the absolute strength of an earthquake. Instead, seismic intensity is a relative measure indicating the degree of shaking felt by people and objects in a specific area during an earthquake.

When a seismic intensity of 5-strong occurs, most people find it difficult to walk without holding onto something. A seismic intensity of 4 corresponds to shaking that startles most people.

This is the first time in one year and seven months since October 2021 that a seismic intensity of 5-strong has been detected in the Tokyo metropolitan area.
