Which earthquakes this page counts
A small earthquake close by and a large one far away can both be what people in Tokyo notice, so one fixed circle would be wrong both ways. This page counts magnitude 6 or more within 800 km; magnitude 5 or more within 400 km; magnitude 4 or more within 200 km; any size within 100 km. That is this site's rule for what to list, not a statement that an earthquake was felt. The earthquakes are the ones the US Geological Survey (magnitude 2.5 and above) and the European-Mediterranean Seismological Centre (magnitude 4 and above) have published; outside the United States, smaller earthquakes are often missing from both.
