What a 4.3 earthquake looks like on a MicroSet graph
Today at 20.38.51 UTC, in the Pacific Ocean 30 Km South West of Lompoc, California, there was an eathquake of 4.3 magnitude at 3km depth. I felt this one as the house shook slightly sideways. The left graph is from the Free pendulum of (D)W5, No.5. The re...
No surprise that the clock noticed, but fortunately for us you had your MicroSet running
Thanks for reporting this - it's interesting to see how sensitive our devices are. Cazalea
Fascinating...
To make such a big difference in the amplitude it must have been pretty powerful. The frequency of the quake obviously coupled better to the fast slave pendulum. Although there are quakes in the Alps with great regularity I have never felt one here in the...
Earthquakes are not all the same
Some shake up and down, some in a wave motion, some left and right, some back and forth. This was back and forth, because the epicenter was about 50km away and fairly shallow at 3km deep under the Pacific Ocean the shorter slave pendulum was also effected...
