Focal Mechanisms

Describes the fault orientation and slip direction of an earthquake and are generated using first motion (up or down) observations.

Solution 1

Number of P First motions: 14

	Plane A	Plane B	Uncertainty
Strike	95	234	18
Dip	65	32	8
Rake	-70	-126	40

Discrepant Stations

Stations whose observed first-motion does not match the predicted first-motion from the focal mechanism.

Station	Network	Channel	Polarity	Quality
PANH	CC	BHZ	D	0.92
WPW	UW	EHZ	D	0.98
B018	PB	EHZ	U	0.92

Solution 2

Number of P First motions: 14

	Plane A	Plane B	Uncertainty
Strike	340	78	10
