How was Troy VI destroyed?

Troy VI was destroyed by a violent earthquake that occurred shortly after 1300 BCE.12

While some early researchers identified this layer as the city described in Homeric tradition, this conclusion is generally considered inaccurate because the destruction was caused by seismic activity rather than a military sack, and the presence of Mycenaean pottery in the debris suggests a date too early for the Trojan War. Following the earthquake, the site was rebuilt by survivors to form the settlement of Troy VIIa.1
