Location Uncertainty: 

Parameter	Value	Uncertainty
Magnitude	4.8 mb	± 0.14
Location	27.879°N, 128.229°E	--
Depth	64.1 km	± 3.3 km
Number of Phase Applied1	33
Minimum Distance2	115.7 km (1.04°)

Azimuthal Gap4	122°

¹Number of phase Applied: 

In determining location of hypocenter, applied number of observations on P waves and S waves. The greater the more accurate prediction of EQ.

²Minimum Distance:

 Horizontal distance of nearest Station measured in Km from epicenter. The smaller the more accuracy in prediction of depth of EQ.

³Travel Time Residual:

 A way of measurement of fit of arrival time observed to arrival time predicted for particular location. The smaller the better fit of data.

⁴Azimuthal Gap: 

Expressed in degree; the smaller the smaller the error in horizontal positioning of EQ. Large uncertainty is considered when exceeds 180° (both depth and location)
