Ground motion information:

NGA Record Sequence Number 5832

Magnitude = 7.2
Closest Distance = 26.6 km
Hypocentral Distance = 28.45 km
Vs30 = 275 m/s
Mechanism = Strike slip

Tp = 8.43 s
PGV = 56.3 cm/s

Orientation of strongest pulse, relative to north = 284 degrees
Orientation of strongest pulse, relative to fault parallel = 71 degrees
Pulse in fault normal direction = 0
Pulse due to directivity = 0


Comments:

The pulse isn't very strong, and this isn't a directivity geometry.

Directivity parameters:


X = 0.11
s = 16.43 km
θ = 58.6

Y = 0.24
d = 2.85 km
φ = 66.4

IDP = 0.52
Rowshandel parameter = -0.62
