Identified earthquakes LIGO data Home

The quake reported as occurring on 1/2/06 at 22:13:40.49, at -19.9260 -178.1780 and was detected in the LIGO data. This quake is also the quake seen on my first identified earthquake post, It is a 7.2 magnitude earthquake that occured later in the day as depicted on the graph.

code 2006/01/02 22:13:40.49 -19.9260 -178.1780 582.90 7.20   Mw  646          1.11  NEI 200601024076 code

Here are the LIGO plot(s) within a small frame of time:

Its distance from LIGO was **9451.87 km** (x). I got this the same way using the measurement tool in google maps.

Its inception was at 22:13:40.49 and using the same math I did for my first case...

(9451.87 km/ 1) X (1 sec./ 6 km) = 1575.312

(1575.312 sec./ 1) X (1 min./ 60 sec.) = **26.26 minutes** (y)

We can determine that the quake was detected 26.26 minutes later at LIGO so that would be about 22:39:55 which is where the earthquake spikes on the graph above so we have a match.

The speed the earthquake traveled in that time is..

9451.87 km/ 26.26 min. = **359.93 km/min.** or **5.99 km/sec.**

These are plausible wave speeds, based upon this [|site]. For this quake it is also easy to tell there are P-waves because looking at my google map, the space between the quake and LIGO is almost entirely water.
