| The growth of the mountain was occasionally interrupted by major eruptions, leading to the collapse of the summit to form calderas. | WIKI |
| The most recent collapse event at the summit of Etna is thought to have occurred about 2,000xc2xa0years ago, forming what is known as the Piano Caldera. | WIKI |
