 | | This intraslab subduction zone event, named the Nisqually earthquake, is a result of high-angle normal faulting due to downdip tension in the subducting Juan de Fuca Plate, and it is similar in mechanism to events that occurred on April 13, 1949 (Puget Sound event of M |
 | | The hypocenter for the earthquake was preliminarily located at N47.1525° and W122.7197° at a depth of 52.4 km, and the causative fault plane has a strike of 357° and dips to the east at 69°. |
 | | This preliminary report is based on a field reconnaissance of the geotechnical effects of the Nisqually earthquake in the Olympia, South Seattle, and Tacoma areas by a group of researchers and consultants during the period of February 28, 2001 to March 7, 2001. |
