Earthquakes
I am an amateur who has been following earthquakes for about 40 years. Notice
that the bigger ones tend to come in cluster – often far apart. Back when US
was still going to the moon, there was an experiment that caused the moon to
"ring". Got to thinking about similar effect across plates that might lead to
earthquake prediction based on mathmatic tracking of vibrations across/through
plates. Do not have the math skills to work out the equations. also looking
for a free/inexpensive map program to help track earthquakes. If you find
anything, would you mind passing it on?
