Re: Kp=7 magnetic storm

All

So far the 5M quakes were first south of the Equator, in Indonesia, then transglobally in northern Chile. There was also a quake further south.

Following the latest downturn in the solar electron flux red graph from near the median with the blue line above the red there was a quake north of the Equator, a 5.2M in Honshu, Japan, fulfilling that prediction.

All this happens in the environment of a minor geomagnetic storm with Kp values still in the 4 and 5 range, while the protons continue to sit on the floor.

Will Honshu trigger something on the West Coast?
From Honshu to San Francisco is a "great circle route" along the northern fault of the Pacific tectonic plate (check it out on a globe or one of the USGS maps centering on the Aleutians). With the Juan de Fuca plate guarding California and a low 5M magnitude, I would guess any quake in San Francisco/San Simeon only has an outside chance for today.

So why are the plots in the second and third graphs so different, when superficially they seem so similar? I prefer the second because of the median reference line.
