View of a trench performed on the Jarácuaro paleo island, south west margin of Patzcuaro lake, showing lacustrine sediments (diatomites and clays) interlayered with volcanic deposits. Different deformation phases are recorded as result of phenomena of  uplifting and landslides of volcanic edifices as well of active faulting associate with the E-W regional fault system. This image justify the importance of the studies carried out by Víctor Hugo Garduño Monroy (on the right) to understand this factors in the lacustrine basin evolution and paleoenvironmental reconstruction in Mexico.
