1465 mystery eruption
The 1465 mystery eruption was a large volcanic eruption conjectured to have taken place in 1465 or "the early 1460s". The location of this eruption is uncertain, as it has only been identified from distant ice core records and atmospheric events around the time of King Alfonso II of Naples's wedding in 1465; it is believed to have been VEI-7 and possibly even larger than Mount Tambora's 1815 eruption.
