with web pages linked from here are those determined at various times
following the earthquake with different types of seismic data.
Although, given the data used, they are legitimate estimates of magnitude
they are not considered the official magnitude.
The region name is an automatically generated name
from the Flinn-Engdahl (F-E) seismic and geographical regionalization scheme.

these regions are defined at one-degree intervals and therefore differ from
irregular political boundaries.
