• flower structures positive flower: uplift of the fault so mostly during thrust/revese faults negative flower: sinking of the walls so mostly during normal faults - 
• Earthquake types of waves general Body Waves: p- and s-waves (non destructive) ->move in all directions and generate surface waves as they hit the surface Surface waves: Love and Rayleigh waves (destructive)
• Details P and S waves Primary waves: travel through solid, liquid and gas and are the fastest waves                                                   Move in the direction the impact came from (back and forth) Secondary waves: Travel only thru solid as its shear force (cannot travel thru liquid), slower                                    move perpendicular to the impact movement                                                                                 
• Details surface waves surface waves are destructive waves  Love waves move like s-waves (shear) and are faster than Rayleigh waves in the seismopgraph East-West (x) Rayleigh waves move horizontal and vertical - oscillate and are the z direction in the seismograph
• how to calculate the location of an earthquake by the time difference of P and s waves at min 3 stations
