What is another word for peak ground motion?
Pronunciation: [pˈiːk ɡɹˈa͡ʊnd mˈə͡ʊʃən] (IPA) 
Peak ground motion refers to the maximum recorded seismic movement during an earthquake. Synonyms for this term include peak ground acceleration, maximum ground motion, peak ground velocity, and seismic intensity. These terms are often used interchangeably and can vary depending on the source of the earthquake data. Understanding and accurately measuring peak ground motion is important for assessing the potential damage and risk associated with seismic events. Seismologists and engineers use these synonyms to describe the intensity of ground shaking and to design earthquake-resistant structures and infrastructures. While each term may have slightly different nuances, they all describe the strength of seismic waves at a given location during an earthquake.
