These dates describe records stored by JISHINDESU, not the station’s operating period. No newer entries does not mean there were no earthquakes or that the station has closed.
JISHINDESU links this station to Kozaki Town in Chiba. Explore the locality or prefecture history to see readings from other associated stations, too.
One station's Shindo reading does not describe shaking across a whole municipality or prefecture. Area pages combine records from stations associated with that area.
Showing the 50 most recent stored events out of 363. All times use Japan Standard Time (JST).
Only events stored for this station are included. A year without entries is not evidence that no shaking occurred.

This is not JMA’s Earthquake Early Warning service. You save a place, not a subscription to this particular station.
Shindo describes shaking at the measurement point. Magnitude describes the size of the whole earthquake. Nearby stations can record different Shindo values for the same event, and a station reading is not an exact measurement at your home.
Understanding the Shindo scale →We display observations stored by JISHINDESU from JMA and P2PQuake reports. The history may be incomplete and reports may be revised. Maximum Shindo here refers to available records, not the station’s entire history.
