As of date of posting T+80 looks like a special.

No double occluded fronts showing though; even though the High
currently dispersing towards the N. Med. coast, is stretching out.

I wonder if the two given for T+24 indicate they are connected with a
change of spell? A severe shock would so why not a couple of small
ones on top of each other within a time limit excluding severe shocks
elsewhere?

"Another problem that needs to be addressed is the magnitude.

Presently the NEIC list gives an average magnitude based on the
resolutions that come in over two or so hours. Without enough
seismometers in the area of the epicentre this is a difficulty.

The other factor is that the earthquake measurers take account of the
time of the pulses involved. Which touches on the question Alexis
posed.

If the meteorologists in charge of oversight of tropical storms for
example took into account the length of time that a storm was at
maximum intensity, then it would be a piece of cake to equate
amplitudes between them."

Accounting for energy that storms develop is an almost impossible task
even for the relatively rare tropical ones than need this degree of
attention. One couldn't expect it for relatively minor ones even when
they signal tornadoes in North America.
