text_A: While there were relatively few major conflicts (either political or military) during Titus's short stint as ruler, there were some major disasters. A few months after his accession, 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. Titus appointed two ex-consuls 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, he 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?
NO.
