Caught a Wave Undulation West to East Round the World

[Kojima]

Monitoring a Jolt in a heliplot, I noticed a wave undulation sometimes appeared at some GSN stations. So I collected a heliplot image where it appeared, and arranged the date and time and the observation station, and plotted them on a map with numbering in chronological order. Here is the data for four days, from 2014-02-25 to 2014-02-28. 

I also noticed that there was no wave at TARA (Tarawa Island, Republic of Kiribati) for 23 hours started both at 2014-02-08 15:00 and at 2014-02-11 11:00, but I found a wave at TARA appeared at 2014-02-25 16:00, and it appeared afterwards every approximately 17 hours; 2014-02-26 09:10 (interval: 17 hr 10 min), 2014-02-27 02:40 (interval: 17 hr 30 min) and 2014-02-27 (interval: 17 hr), the last wave appeared very small. And I could not notice the next wave with a 17 hrs interval, I'm not sure if I missed it or there was not a wave at that time. But the next wave appeared at 2014-03-01 06:00 (interval 34 hr 20 min) and about 2 hours later of the wave a Big Spike happened with following tremor for 3-4 hours. The next wave appeared at 2014-03-01 23:20 (interval: 17 hr 20 min) with some bigger wave form.

A wave undulation has been appearing on a heliplot at some GSN Stations since 2014-02-25.

When posting this blog, I got a comment from Nancy.

Nancy's comment: 

Your are tracking the wave west to east round the world several times. I did this too on domino quake analysis years ago.

Th waves also are familiar. In 2004 etc when the heioplots were more sensitive, they showed up a lot. Worldwide wobble after a big quake.

Then the sensitivity was turned down. NOW I think the force of the jolts has increased so they are showing up again, even with the helioplots turned way down, less sensitive.

So I made an analysis about the tracking of the wave, showing the following.
