6. Earthquake Detection $ 29  Affordable detectors based on that  P (primary/pressure) wave travels faster than S (secondary/shear) waves, and generate only shock  Slower S waves are destructive  Early earthquake warning systems consisting of seismic motion sensors networked with computer(s)  Issue warning based on likely strength and progression of seismic events and  Can allow warning 20 seconds or more before ground motion.

AT 703 PM CDT...NATIONAL WEATHER SERVICE METEOROLOGISTS AND STORM SPOTTERS WERE TRACKING A LARGE AND EXTREMELY DANGEROUS TORNADO. THIS TORNADO WAS LOCATED 6 MILES SOUTHWEST OF SAVOY MOVING NORTHEAST AT 45 MPH. THE TORNADO WILL BE NEAR... CHAMPAIGN BY 720 PM CDT... RANTOUL BY 729 PM CDT… PAXTON BY … A TORNADO WARNING MEANS THAT A TORNADO IS OCCURRING OR IMMINENT. YOU SHOULD ACTIVATE YOUR TORNADO ACTION PLAN AND TAKE PROTECTIVE ACTION NOW. SIGNIFICANT DAMAGE HAS OCCURRED WITH THIS SIGNIFICANT TORNADO! THIS IS AN EXTREMELY DANGEROUS AND SERIOUS LIFE THREATENING SITUATION..  Sound tornado sirens  Unlock shelter doors  Turn on spot lights on shelters  Adjust traffic signals on routes to shelters  Enable outside doors in homes to open when the storm hits.
