Ask A Geophysicist Anything You need About Earthquakes

The two chief “ sapidity ” of temblor waves are phosphorus wave and S undulation . P wave arrive first followed by the S wave . The most crucial aspects of P waves is that they travel very well through the dead body of the Earth while S moving ridge travel well along the surface of the Earth . They both can be observe at the surface but the S wave tend to demonstrate big Earth’s surface amplitudes than the P wave for shallow , damaging earthquakes . It its hypothesise that animals , being closer to the ground and more attuned to quiver in general , ( we humans have ascertain to brush aside so much noise we create in our environment ) have felt the depressed bountifulness P waves , which can come several seconds to many 10 ’s of indorsement before the S waves for large distant earthquake . So of course this gets assign to beast predicting them … in realness is seems they just sense them before people do . That said … In my experience , cats lean to be very unpredictable .
