The 10 historical earthquakes nearest to reference event 08031723584c
located at 48.0640 120.8143 that occurred prior to 08031723584c. 
The list includes events with magnitude (Mag) > 3.0 and gives distance
and azimuth  from the reference event to each historical earthquake.

Date is given in Universal Time (UT). Subtract 8 hours to get Pacific
Standard time (PST) or 7 hours for PDT. Azimuth is the compass
direction (measured clockwise from North, 0-360 degrees) of the
earthquake from the location of the reference event. Usually, depths
listed as 0.0 km are either unknown or very unreliable.
