文摘

We study the enigma of the nested craters of Láscar. TLS data provide detailed quantitative information on their geomorphology and structures. Analogue sandbox models give insights into the interaction between the nested craters. We propose that one of the craters is a ‘parasite’ crater. This concept of a ‘parasite’ crater is likely applicable to other volcanoes worldwide.
