Mars 
						is alive with geophysical activity. 
						
							
							
							Geophysics means the study of Earth’s physical 
							processes. 
						
						
						For 
						planetary scientists, the idea of such processes 
						occurring on Mars was once highly improbable, if not 
						unthinkable.
						
						Mars has no coherent global magnetic field, an 
						atmosphere one half of one percent as dense as Earth’s, 
						and no tectonic plates. 
						 
						
						
						Scientists are puzzled by the dynamic actively on Mars - 
						towering dust devils, planet-engulfing dust storms, 
						mysterious aurorae - and the recent discovery of 
						hundreds of unexplained seismic events.
						
						Independent researcher Stuart Talbott begins by 
						analyzing the largest martian quake detected in May 2022 
						- which was equivalent to the cumulative energy of all 
						other marsquakes detected to date.
