Earthquakes Japan 2012

This is an overview of all the earthquakes in Japan in 2012, sorted per magnitude and shindo (震度, shaking intensity). This data was generated by using the Japan Meteorological Agency database.

The most earthquakes in a single category were shindo 1 and magnitude 3-3.9, the total amount was one third from last year.
Shindo 1 earthquakes ranged from magnitude 0 to 6.9.
Shindo 2 earthquakes ranged from magnitude 1 to 6.9.
Shindo 3 earthquakes ranged from magnitude 2 to 6.9.
Shindo 4 earthquakes ranged from magnitude 3 to 7.9.
Shindo 5- earthquakes ranged from magnitude 5 to 7.9.
Shindo 5+ earthquakes ranged from magnitude 5 to 6.9.

Below the frequency distribution of earthquakes during the year is shown:

Comparing the JMA statistics with the data from their database, five earthquakes were missing from the data in the database (four of shindo 1 and one of shindo 3).
