Earthquakes are common occurrences along the Pacific Mexico coastal areas south and southeast of Acapulco.  In fact,  the area between Acapulco and the mid-point of the State of Oaxaca's coastline may be the most active earthquake zone in the country.

Earthquakes actually occur on an almost daily basis,  sometimes two or three a day;  but serious damage isn't typically or often the result.  However,  international organizations may consider the area in and around Acapulco to be  high risk  -  given its proximity to the earthquake zone and/or because of poor construction techniques utilized in years past.  If you have a chance to observe some of today's on-going new condominium construction in  Zona Diamante and south of there,  you may see some of the special measures being taken to reinforce these buildings,  as a precaution against any future quakes.  Some tourists in Acapulco may feel earthquake tremors,  though most don't;  and many probably sleep or drink right through them,  unaware and unfazed.
