Hi Folks, This morning's monitor indicated a large signature. At first
glance it looked like one event followed by two more.
I saw a report of the 4.2M Western Montana, but when I processed it, the
time indicated matched only the last part of the trace. See image one
showing all three sensors.
It's very clear on the bottom trace, a Slinky II machine CH3, which is a
vertical spring sensor.
The P and S show the MONTANA earthquake. For more details, see
09306.105022.tcidch3.gif.
Later I found the other parts of the trace were from a 6.4M NORTH OF
SVALBARD near Greenland. (See 090306.105022.tcidch1.gif).
Makes me wonder if the Svalbard earthquake , encouraged the Montana
earthquake as it shook things up, as it passed through?
Ted
