The archaeological digs at the site extend to the street level of the 79 AD volcanic event; deeper digs in older parts of Pompeii and core samples of nearby drillings have exposed layers of jumbled sediment that suggest that the city had suffered from the volcano and other seismic events before then. Three sheets of sediment have been found on top of the lava that lies below the city and, mixed in with the sediment, archaeologists have found bits of animal bone, pottery shards and plants. Using carbon dating, the oldest layer has been dated to the 8th-6th centuries BC, about the time that the city was founded. The other two layers are separated from the other layers by well-developed soil layers or Roman pavement and were laid in the 4th century BC and 2nd century BC. It is theorized that the layers of jumbled sediment were created by large landslides, perhaps triggered by extended rainfall
