What is another word for peak ground acceleration?
Pronunciation: [pˈiːk ɡɹˈa͡ʊnd ɐksˌɛləɹˈe͡ɪʃən] (IPA) 
Peak ground acceleration (PGA) is a seismic measurement that quantifies the maximum acceleration of ground motion during an earthquake. Synonyms for PGA include ground acceleration, peak horizontal acceleration, peak vertical acceleration, and maximum ground acceleration. These terms are often used interchangeably, and refer to the same fundamental concept. Other related concepts include peak ground velocity (PGV) and peak ground displacement (PGD), which measure the maximum velocity and displacement of ground motion, respectively. Understanding these terms is crucial for seismic hazard analysis and engineering design, as they provide critical information on the potential impact and damage of earthquakes on structures and infrastructure.
