Subject: Meteor impacts/UFO crashes and earthquake lights

Greetings everyone,

Below is a briefly edited reply <my comments in brackets>
to questions I asked Bob Wetmiller, a seismologist with the
Geological Survey of Canada in Ottawa, regarding meteor
impacts and earthquake lights.  Bob even tells how we can
produce and observe earthquake lights in our own kitchen.

Hi Nick


* The seismic signal produced by a meteorite impact would look
similar to that produced by an explosion or an earthquake.
In principle the signals should be different because of the
differences in the source, but in practice the simiarities
are more obvious than the differences. I am aware of one
example of a seismic record for a meteorite impact in Canada
and would not suspect the record as being anything other than
an earthquake at first glance.  <Unlike natural earthquakes,
explosions usually have a much larger initial signal compared
to the rest of the seismic signal that follows.>

You should also be aware that there are more examples of seismic
stations recording the sonic booms of meteorites <and aircraft,
UFOs, etc.> than impacts. In those cases the seismic records are
bizarre. <Seismic records have been used in one case to determine
that a Canadian military plane was flying too fast creating a
sonic boom which were picked up by seismometers along its flight
path all the way back to its base.  In another unusual case, the
trajectory of the 1965 Keckburg UFO crash was determined using
the seismic signals from different seismometers in Canada and
the U.S.>

* Magnitude 3 represents a big explosion. There is no single
relationship between magnitude and charge size because much
depends on what happens at the source, but the largest explosions
set off in the mining industry anywhere in Canada, and they do
some big ones, seldom exceed Magnitude 3.5.  <I got an e-mail
message from Steve Roecker, a U.S. seismologist who has worked
in Kyrgyzstan for many years, and he has not heard anything or
detected any seismic signals which could be connected to the huge
Russian UFO crash which was reported earlier on UFO UpDates.>

* Surface explosions seldom generate aftershocks, but it is
common in underground mining for explosions to be followed by
induced seismic activity. It all depends on the stress conditions
at the site of the explosion.

* We have never seen any credible reports of lights accompanying
earthquakes in Canada, but there have been some. Generally they
are very hard to qualify, but there could be something going on.
Next time you take a tray of ice cubes out of the fridge, turn
off all the lights before you crack the tray. You will see lights
produced when the ice cracks. <Try this and lets compare notes.>

* The light flash associated with the North Carolina earthquake
could just be coincidental. Its hard to tell from the report
you've given and I have not heard about other reports on the
event. I will let you know if something comes along to explain
it further. I doubt there was any meteor involved. <Especially
since the source of the earthquake was located not far from
Charlotte, NC, a fair sized city.  One would expect a crater to
have been reported if it was a large meteor impact.>

Good to hear from you again, Nick. Take care.

Bob Wetmiller
