August 24, 79 AD, started out like any other day in the thriving Roman town of Pompeii, with citizens socializing at the public baths, watching gladiator contests, preparing meals and going to school. The popular resort town was located in the shadow of Mt. Vesuvius, which hadn't erupted in hundreds of years.
A series of small earthquakes in the last few days may have caused some uneasiness, however. Only seventeen years earlier, a big earthquake had caused massive damage, which the citizens of Pompeii were still trying to repair. At the time, the correlation between earthquakes and volcanic activity was unknown; but the longer a volcano is silent, the bigger the explosion when it finally does erupt.
