Counting the Dead

,,
,,
Of the towns and villages that were overrun, Pompeii provides us with the most comprehensive picture of the effects of the eruption on the populace and the sequence of events that accompanied it. While Herculaneum was equally devastated, the effects on the population were different. As the town didn't suffer from the initial fallout of volcanic debris, more of the population had time to escape before the pyroclastic surges overwhelmed the town.

The number of inhabitants of Pompeii at the time of the eruption is still open to debate, ranging from around 6,000 to over 20,000. The number of victims recovered, however, is more certain, totalling 1150 identifiable bodies so far. Of these, 394 were found in the lower pumice deposits while 650 were found in the upper pyroclastic deposits. If we assume that there is a similar distribution of victims in the unexcavated areas of the city, the total number of dead in the city due to the eruption must be in the order of 1600.

During the first phase of the eruption a hugh quantity of pumice fell on Pompeii, burying the city to a depth of 2-3m. During this phase, most of the inhabitants managed to leave the city. However, 38% of the known victims were killed during this phase, mainly as a consequence of roofs and walls collapsing under the increasing weight of the pumice deposit.

During the second phase of the eruption, 51% of the casualties were inside buildings, while 49% were outdoors. All of the inhabitants in this phase however, regardless of their location, were killed by the pyroclastic surges that overran the city. Some of the inhabitants must have survived the first pyroclastic surge, as their bodies were found above the lower pyroclastic deposits.

Plan of Pompeii


The following tables show the distribution of bodies found in Pompeii in each phase of the eruption. Reference is made to the location of the victims within the city - Regio I, Regio II, etc. These divisions are marked on the accompanying plan above. For a fuller description of the labelling of areas within the city refer to the Map of Pompeii.

From the tables it can be seen that during the first phase of the eruption most of the deaths occurred within buildings, killed by the collapse of roofs and walls under the weight of volcanic debris. During the second phase, when people had elected to either stay inside to wait out the eruption, or to leave the city when they could, the ensuing pyroclastic surges killed those that they engulfed, regardless of their location.
