[irised] M7.3 Caribbean Earthquake

[John Lahr]

Dear Teachers:

This is a notice of the earthquake that occurred today (Thursday) 
within the lithosphere that has been subducted beneath the eastern 
edge of the Caribbean plate.  Due to the great depth (145 km) the 
surface wave are not a prominent feature of the seismogram.  Rather 
than an attachment, I've posted the information 
here:  http://jclahr.com/science/psn/as1/windward07/index.html

This event should have been well recorded on all operating seismic systems.

Cheers,

John Lahr
