The 10 historical earthquakes nearest to reference event 98102105252c
located at 45.9403 122.0785 that occurred prior to 98102105252c. 
The list includes events with magnitude (Mag) > 3.5 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.
