Mount Vesuvius erupted in 79 AD in Italy. This dangerous volcano buried two Roman towns. The names of the towns were Herculaneum and Pompeii. Herculaneum and Pompeii have some differences and some similarities. Here are a few. Both of the towns are coastal towns, and they were both buried by the same volcano. Additionally, they were in the Roman Empire.
Here are a few differences of the two towns. Pompeii is a much bigger city while little Herculaneum stands aside like a little mouse because it is so small. Pompeii had a population of 20,000 people, while Herculaneum had only 4,000.
When Vesuvius erupted, it covered Pompeii in hot ash, while Herculaneum was buried the next day by a pyroclastic flow. Archeologists have excavated both towns. What you can see now is all that they have uncovered. Today, anyone can walk through the streets as if the markets were still alive.
