Strong Motion

Strong motion refers to the intense vibrations experienced during an earthquake that can cause structural damage to buildings, bridges, and infrastructure. These movements are measured by specialized sensors called strong motion accelerometers, which record the acceleration forces in the ground and structures. The magnitude of strong motion depends on factors like the earthquake's size, depth, and distance from the site. Understanding strong motion helps engineers design safer buildings and infrastructure capable of withstanding such forces, minimizing damage and protecting lives during seismic events.
