A surface wave in which the individual particles of the material move back and forth in a horizontal plane perpendicular to the direction of wave movement.
                                                            
                                                     
                        
                                                
                        
                        
                            A major type of surface wave having a horizontal motion that is shear or transverse to the direction of propagation. It is named after A.E.H. Love, the English mathematician who discovered it.
                                                            
                                                     
                        
                                                
                        
                        
                            A type of seismic surface wave having a horizontal motion that is transverse (or perpendicular) to the direction the wave is traveling. Ma. An abbreviation for one million years ago (Megannum).
