Location : Position of Epicenter 

20.079°N 155.793°W

Depth : Depth of starting Rupture 

16.8km (10.4mi)

Region : Waimea, Hawaii

Directions and Distances :Directions and Distances from Geographical Reference in Close Proximity Which can be effected by Location Uncertainty

a)  14km (9mi) WNW of Waimea, Hawaii

b)  52km (32mi) NNE of Kailua-Kona, Hawaii

c) 83km (52mi) WNW of Hilo, Hawaii

e)  254km (158mi) ESE of Honolulu, Hawaii

Location Uncertainty: 

Parameter	Value	Uncertainty
Magnitude	4.5 Ml	± 0.20
Location	20.079°N, 155.794°W	± 0.5 km
Depth	16.8 km	± 1.0 km
Number of Phase Applied1	82
Minimum Distance2	5.0 km (0.04°)
Travel Time Residual3	0.14 sec
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)
