Colima volcano (Mexico): July 2015 Montitlán pyroclastic flow deposit a year later
On 11 July 2015, a large dome collapse triggered the second largest block and ash pyroclastic flow of the 21st century (surpassed by Merapi in 2010 only), filling and devastating the Montitlán river valley on Colima's south side to a length of about 10 km.
We visited the deposit approx. 16 months later, in Nov 2016 (compare these to photos taken few days after it was deposited
). This fresh, the deposit is a fantastic geologic showcase. It provides extremely interesting insights into the dynamics of this kind of pyroclastic density currents and its origin:
