Identified earthquakes __LIGO Data Home__

The quake reported as occurring on 1/2/06 at 06:10:49.76, at -60.9570 -21.6060 was detected in the LIGO data.

This graph below depicts two earthquakes. The first one is 7.40 and the second is 7.2. Even though the first one has a greater magnitude the second earthquake is about twice as big as the first. Why is that? You can check out my case for the second earthquake here.

Here's the LIGO plot(s):

Its distance from LIGO was about **14850.8 km** (x). I found this by using the measurement tool in google maps so its pretty accurate. The second quake that you can see occuring around 22:30 is about **9354.24 km** from LIGO.

The earthquakes inception was at 06:10:49.17 and using math...

(14850.8 km/ 1) X (1 sec./ 6 km) = 2475.133 seconds

(2475.133 sec/ 1) X (1 min./ 60 sec.) = **41.25 minutes** (y)

The earthquake was detected 41.25 minutes later at LIGO in Hanford therefore it was at 06:52:04.

Heres the plot of the first earthquake zoomed in:

The speed it had to travel to cover that distance in that time was...

14850.8 km (x)/ 41.25 minutes (y) = **360.019** **km/min.** or **6.0003 km/sec.**

These are plausible wave speeds, based upon this [|site].
