A certain characteristic motion wave, a large wave like a very complex serration continuing rhythmically for a few hours,

was recorded at eight stations in Michigan on May 27, 30, or June 4, 2014.…

Watching heliplots on LISS (Live Internet Seismic Server) site,

we can see jolts occurring at some stations, VNDA, LBTB, LPAZ, PLCA, BOSA, CPUP and DBIC, weekly, …

For my understanding I made a chart from "ZetaTalk: Characteristics" shown below.…

On 2014-03-25, a pattern of jolt appearance in a series at seven stations changed after continuing six times every one week since 2014-02-11. In the 7th series, a jolt appearance changed at two stations of LBTB and PLCA while there was no change at the other five stations.  

I found a jolt in a heliplot of GSN Stations on 2014-02-11.

A jolt…

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…

At first I'd like to show that a vertical time axis, Hour, in a heliplot can be displayed with slipping off for one hour, which sometimes happens when a heliplot screen is updated, and I have noticed it since the first series. 

An example is the following figure.…

As shown in a previous blog of "Jolt in Antarctica, Africa and South America some days after M6 Scotia Sea 2014-02-08", a series of Jolt was recorded at some GSN stations in Antarctica, Africa and South America some days after M6 Scotia Sea 2014-02-08. 

A jolt began at 14:10 UTC of…

As mentioned in the previous blog of "Global Tremor after M6 Scotia Sea of 2014-02-08", I noticed that JOLT, not tremor, was recorded at some GSN stations in Antarctica, Africa and South America some days after the earthquake. I show a map of the…

The Scotia Sea earthquake of 2014-02-08 was M 6.0, not huge, but the distinct tremor was recorded at almost all GSN stations of the world. It seemed unusual.…

For my understanding I made a chart from "Survivors, a Matter of Mindset" in BBS Archives.

Thank you very much, Nancy, for the excellent lecture!
