What had happened in 62 ad that already destroyed many of the buildings in pompeii?

In 62 AD, a significant earthquake struck the region around Pompeii, causing extensive damage to many buildings and structures. This seismic event led to the collapse of walls, roofs, and other architectural elements, prompting repairs and renovations in the town. The earthquake served as a precursor to the more catastrophic eruption of Mount Vesuvius in 79 AD, which ultimately buried Pompeii under volcanic ash. The damage from the earthquake highlighted the vulnerability of the city to natural disasters.
