NB:
The official magnitude for this earthquake is indicated at the top of this page.
This was the best available estimate of the earthquake's size,
at the time that this page was created. Other magnitudes associated
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.
The boundaries of
these regions are defined at one-degree intervals and therefore differ from
irregular political boundaries.
