Looks like a phase for large earthquakes.

What seems to be required is a large cyclone running at about the same
time.

So if the run is true then the time with that storm is as for 15:45
without one.

Feck, I'll never get the hang of these!
15:00 is for thunder so maybe it's 15:00 with nobs on?

So... there should be a large number of seriously severe quakes for
the lunar phases when the time is as for a thunder spell plus that 40
to 45 minutes?

If I had any sense I'd check this stuff out before I posted it. But
how can I be expected to watch telly, format and hard drive and post
this crap as well as check my facts?

Be reasonable.

Hang on, the penny is falling through...
Ah, good old get out clauses.
I need a variable such as ... hmmm... well I'm sure I can come up with
something by the time I do look.

Something to do with storms. I'll have to check all the angles.
