Along much of the western coast of North America, however, the Pacific Plate is in the process of sliding past the North American plate at plate intersections called transform faults (see plate tectonics).
A man received an electric shock last night while walking over a metal plate at the intersection of Broadway and White Street, in Lower Manhattan, in the rain, the Fire Department said.
This procedure is repeated for all pixel rows of the plate image and the intersection of the peak values of rows and columns having the highest 75th percentile values are used to identify the approximate center of each spot, as depicted in Figure 1c.
The mainshock hypocenter was relocated slightly westward from that reported by Japan Meteorological Agency JMAA), placing it near the intersection between the plate boundary and the Moho of the overriding plate.
Tokyo is located above the complex intersection of two subducting plates: the Pacific plate which is subducting beneath the Okhotsk plate from the east, and the Philippine Sea plate, which is subducting beneath the Okhotsk plate from the southeast, as shown in map view and cross section in Figure 4.
The location of the mainshock hypocenter almost coincides with that of the intersection of the plate boundary and the Moho.
It is found that the clearance at the brace end on the gusset plate, the locations of the intersection point of bracing members, and the ratio of the free edge length to the gusset plate thickness are the key parameters.
Considering the x-z coordinate with an origin at the Japan Trench axis as shown in Figure 3, we can define the point of intersection of the plate boundary décollement and the back-stop interface, which might be a splay fault, and also the point of intersection of the slope surface and the back-stop interface.
In old, cool subduction zones, such as those in northern Chile and Alaska, the downdip limit of interplate earthquakes is much shallower than the depth at which the temperature of 350°Cis observed, but approximately corresponds to the intersection of the plate interface with the forearc Moho (e.g. Oleskevich et al., 1999).
In contrast, in the central segment B, no large interplate earthquake is known to have occurred beneath the forearc mantle wedge, and the downdip limit of large interplate earthquakes, about 20 km, approximately corresponds to the depth of the intersection of the plate interface with the forearc Moho.
