August 24, A.D. 79-
1:00 pm- The first signs of smoke coming out of Mount Vesuvius were spotted reaching 9 miles into the sky. People knew that it was time for them to leave their homes when the ash began to fall on their roofs. Many of the people gathered up all the belongings that they could and went out into the streets. Some of the people tried to escape on boats through the sea and others waited on the beach.
Midnight- The people that were on the beach would have had a perfect place to watch the lava spill down the sides of Vesuvius but they would have quickly been over taken by the ash, heat and burning embers that were spilling out of Vesuvius so they would not have seen much.
August 25, A.D. 79
1:00 am-Clouds of gasses and ash continued to spill down Vesuvius onto the city of Pompeii. The anthropologist Paolo Petrone and the vulcanologist Giuseppe Mastrolorenzo were able to use the bone fractures and the position the remains were found in to know that the people were in a 900 degree Fahrenheit cloud that caused them to die within seconds.
7:00 am- the final cloud bust down and killed the remaining people of Pompeii.
8:00 am-Pompeii was silent.
