I logged in to the Talkshop and glanced at the space weather graphic, a step rise in proton flux today, a distinct event..

M7.3 – 18km SE of Kodari, Nepal

Apart from a possible geomagnetic movement, not timed well, nothing else appears in the spaceweather see below.
Google scholar produces a list of works on possible linkage. The assertion generally seem to be a precursor, doesn’t seem so in this case
I take this as a co-incidence, particularly if the earlier severe earthquake had no such association. Perhaps someone is better able to dig this out from high resolution data archives.
[update]
Looks like a new cluster.
I take this as null. There is no 1:1 correspondence of any space weather with earthquakes. There is extensive supposition of some kind of vague linkage. Mechanism? Unknown.

M6.3 is about 20x less powerful than M7.8.
[mod: see below and article]
Tim:- M7.3 The article was written fast, little time for checking, has been updated
Was there any similar jump before the original quake?
I’d like to know too Rog. Think I’ve found the data archive.
Article updated with location map, looks like a new cluster.
The crustal faults around there are severe, been quiet in recent years. Stress relieves in one place, rises in another.
Both M6.3 and M7.3 are correct. M6.3 was a foreshock. Let’s hope M7.3 is not. Keep your fingers crossed for Sherpas.
Roger: If this is correct, and given I can see longer data here, probably not. There is activity in the days around so whilst it could be viewed as a slightly distinctive pulse, far from evidence.
If anyone else wants to look the rolling data archive is but mostly vanishes after a month.

There is a solar/earthquake connection any way you cut it.

The original Nepal quake was triggered during our crossing of a solar plasma sheet. Today’s quake was triggered by the CME generating an increase in activity, electron flux, wind density, south-pointing IMF, and others.
If there is a place to email more data, I would be glad to. The more folks we can get to understand processes that can trigger earthquakes, the closer we can get to models tracking forces in real-time.
Here is a link to an abstract discussing some of the relationships, Bruce Binion.

As the proton flux per square meter increased by ~ 8 ten Mev protons per second. the kinetic energy of 10 Mev protons is about ten to the minus eighteen joules, and the area of Nepal is about 1.5 x ten to the thirteen M2, the increase in energy deposited over the earthquake zone was about fifteen microwatts per square meter. divided by the shielding factor afforded by the ten tonnes of atmosphere overlying each square meter of terrain.
The salient question accordingly becomes why on earth would anyone take the bloke who raised the question seriously?
We have a magnetic storm. It will sway.
Russell, lets take you back to our days as residents of Wallagonna land.
One day you hear a terrible noise outside. Perfectly reasonably you go outside to find out what is going on. You look around, see some smoke some way off and tiny flash of light right there.
I don’t know whether anyone buried the man hit between the eyes by a bullet and yet a tiny flash of light is so weak.
The unknown is just that. Humans look for patterns, see many where there are none and yet today we are only able to communicate because some patterns have turned out to have definite meaning, we make things.

I can’t take channon back to his days in Dimensional Analysis land, because he evidently has never been near the place.
15 microwatts/m2 summed over the whole area of Nepal adds up to less than 3,000 horsepower- does he imagine a 20 car freeway pileup could stir the San Andreas fault.
O the innumeracy !
Increasing strombolian activity at New SE crater
Update Tue 12 May 19:55
Strombolian activity began again today at the New SE crater. Accompanied by rising tremor, this activity is increasing at the moment.
The current pattern is very similar to many past episodes which often culminated in violent explosive (lava fountaining) and effusive (lava flow) paroxysms and could very well build up to a new one, maybe similar to the previous one during 1-2 Feb this year.

MOSCOW, May 13. /TASS/. An explosion is ruled out as a possible cause for the accident with Russia’s Progress M-27M space freighter than went out of control and was burned in the dense layers of the Earth’s atmosphere, a Russian space expert said on Wednesday.
Depressurization of the oxidizer and propellant tanks of the Soyuz-2.1a carrier rocket’s third stage caused the loss of the Progress cargo ship as was established by Russia’s Federal Space Agency (Roscosmos), Academician of the Russian Academy of Cosmonautics and Cosmonautics News Journal Editor-in-Chief Igor Marinin said.

Russel you seem to be trying to stir where there is nothing to stir.
A somewhat remote sensing system reported a transient event roughly timed to a local event. As we can now see this was a precursor to other solar activity. In both cases more is involved.
What other, more direct linkage between solar and earth system might be involved? I don’t know, you don’t know. My best guess is nothing yet at the same time I know there is lot which gets ignored such as the unmonitored and considerable terrestrial electrical fields. This latter is a subject of active investigation by several teams but not something I follow.
I’d be staggered if anything solar could wholly cause a quake but something which alters the timing of when is more rational. The works on fault stress are giving a pretty good idea on where quakes will happen, vaguely when but some stress points relieve without a quake.
Crustal movement is continuous from orbital forces alone, we are moving right now, simple tidal forces at work.
The Nepal quakes were at a known stick point, was expected sometime. I’ve looked at the recorded events. There was I think a precursor at a slight deeper level the day before the first quake, the big one, a pause and then many aftershocks at slightly shallower depth (10km). Then we come to the quake involving this blog post. Is at a different location, follows a similar pattern. Plotting the lot shows a pretty tight arc at the northern edge. Maybe this is about local topology affecting remote sensing or perhaps there is some kind of tight fault line.

Would this event cause radio blackouts or communications failure? There were 5 plane crashes on this day, Atlanta, Ga – Beach Haven, Seville Spain, Military Helicopter, Napal and Tantipara West Bengal and also the 2 train derailments that the throttle was electrically powered. Maybe all these events are all a co-incidence, I just wanted to get your thoughts? Thanks. ~tina
No.
There was no sign of a major electromagnetic space event.
Sakurajima volcano remains very active – during the day appears to be even 10-12 eruptions – ENEX agency informs.
