Temporal and morphological eruption characteristics of lava flows from the Holocene La Taza monogenetic cone obtained from petrology and LiDAR imagery (Michoacán, Mexico)

The Holocene La Taza andesitic volcano is one of over 1000 volcanic centers located within the Michoacán-Guanajuato Volcanic Field (MGVF) in central-western Mexico. La Taza (~8500–8200 yr BP) represents one possible eruption style within the field, with deposits indicating Strombolian activity follo...
