So, the northern end of the subduction zone shows some wiggling.

Actually, by the looks of THIS one, I would say they haven't stopped

You might find some of your spectrogram excitement there. Just a thought.
So are you suggesting that seismographs are detecting temporal variations of the geomagnetic field
as opposed to slow-slip?
Spectrograms are produced from the timeseries by computing the Power Spectral Density (PSD) of successive 102.4 second (1024 point) segments of data using the Fast Fourier Transform (FFT) technique. Each 24-hour continuous timeseries yields 844 individual PSD plots with 0.01 Hz resolution from 0 to 5.0 Hz. The spectrograms are visualized using a color/intensity map to produce a 2-D image from the data. The DISLIN Scientific Data Plotting library is used to generate the plots.
The magnetic flux density is enhanced by a factor of approximately 1,000 by the high-permeability metal core.
The sensor outputs are amplified by 40,000 and sampled at a 10 Hz rate with 16-bit resolution in a full scale of 10 Volts.

Anyone have any advice on an earthquake preparedness kit that I can make or a link?
( I live on Northern Vancouver Island) Thanks.
Mosquito XEL NO PILOTS LICENSE REQUIRED TO FLY THIS HELICOPTER IN USA**
When your preference in a Part 103 ultralight requires more of a standard fuselage and cockpit then the XEL will meet your needs. The integrated fuselage standard to all XE models forms a most pleasing and aerodynamic shell with all the required instrumentation and comforts a recreational pilot might want. The included safety floats provide an exemption to the standard 103 weight limit to keep this beautiful ship within the ultralight category. This helicopter can also be flown under FAA Part 103 ultralight rules and does not require aircraft registration or pilot license*. The Mosquito XEL is available ReadyBuilt©, as a full kit or can be purchased in sub groups. A deposit as low as $5,000 for the first sub-group or $10,000 for the entire kit will get you an immediate spot on the production line. Videos
