The 1932 Jalisco earthquakes began on June 3 at 10:36 UTC with a megathrust event that registered 8.1 on the moment magnitude scale.[2] With a maximum perceived intensity of X (Extreme) on the Mercalli intensity scale, at least 400 deaths were caused in Mexico and neighboring Guatemala.[2] It was the first of a series of seismic events that affected parts of western Mexico during the month of June 1932, all reaching magnitude 7 or greater.[4]
The Mexican subduction zone, the Middle America Trench, is seismically active and has generated both destructive and non-destructive tsunamis. Each earthquake in the series caused significant damage, injuries, and deaths, and in each case tsunamis of various heights were generated, with the June 22 catastrophic tsunami in Cuyutlán and San Blas being described as one of the most destructive events in the region based on all available historical records.[5]
