Issue Description

Cover image:
Rincón de Parangueo, located in the Santiago Valley, in the State of Guanajuato is a maar that has dried due to the large groundwater extraction required for irrigating crops in the region. The active deformation of the maar’s bottom (which includes both uplift and subsidence) has created a series of structures on its surface. Photo: Jaime J. Carrera-Hernández.
