text_A: Although Titus's brief reign was marked by a number of major military or political conflicts, he was fortunate among rules in that he avoided any major disasters. A few months after his abdication, Mount Vesuvius erupted. The eruption almost completely destroyed the cities and resort communities around the Bay of Naples. The cities of Pompeii and Herculaneum were buried under metres of stone and lava, killing thousands. The two ex-consuls previously appointed by Titus were able to organise and coordinate the relief effort and personally donated large amounts of money from the imperial treasury to aid the victims of the volcano. Additionally, Titus himself visited Pompeii once after the eruption and again the following year.
text_B: From what we have been told about Titus's reign, does it sound like natural disasters were a common occurrence in this part of the world?
YES.
