The different fates of three cities buried by a single volcano
In short: We often view Pompeii as a singular tragedy, but the eruption of Mount Vesuvius was actually a complex series of distinct catastrophes. Depending on their location and the speed of the volcanic flow, neighboring towns faced wildly different ends—some were suffocated by ash, while others were instantly scorched.
In 79 CE, the eruption of Mount Vesuvius did not impact every settlement equally. While Pompeii is the most famous victim, it was part of a broader regional disaster that destroyed communities like Herculaneum and Oplontis. The specific nature of each town's destruction was dictated by its proximity to the volcano and the direction of the ejected material. For instance, the commercial hub of Pompeii largely avoided the most lethal pyroclastic currents but was buried under more than 10 feet of wind-borne lapilli (pebble-sized pumice).
In contrast, the coastal retreat of Herculaneum was spared from the heavy lapilli rain but was instead pummeled by superheated avalanches of ash and gas. Organic matter such as papyrus turned to charcoal as these powerful pyroclastic flows buried the settlement under 60 feet of rock. Meanwhile, Oplontis—situated between the two—suffered from both types of volcanic activity, preserving elaborate frescoes alongside the skeletons of dozens of victims who sought refuge in waterfront warehouses.
The preservation of these sites offers a unique window into Greco-Roman life. Because the ash hardened around the victims, later centuries allowed for the creation of plaster casts capturing their final moments. From bakeries with loaves still in the ovens to lavish villas dating back to the 4th century BCE, the ruins provide a sophisticated record of a society that supported between 10,000 and 20,000 inhabitants before it was frozen in time for nearly 2,000 years.
The timing of these events remains a point of scholarly debate. While some records suggest the eruption occurred around noon on August 24, 79 CE, other scholars believe the disaster took place later in the year, possibly in October or November.
