WebWhen seismic waves are first created, they travel outwards in all direction from their source. Body waves travel through the interior of the earth, and have two main types: P-Waves (Primary waves) are Longitudinal Waves. S-Waves (Secondary waves) are Transverse Waves. P-Waves are fastest at about 6 km/s (kilometers per second) and arrive first. WebSeismic analysis is a subset of structural analysis and is the calculation of the response of a building (or nonbuilding) structure to earthquakes. It is part of the process of structural … WebTypes of seismic waves: S-waves. Secondary waves or S-waves are seismic waves that travel at speeds of about 50% to 60% of the speed of the primary waves. Their effects are hence only felt after the effects of the P-waves during an earthquake. S-waves are also classified as body waves as they move along the inner layers of the Earth. goalsetter one stock one future
