PhD candidate based at the Natural History Museum (NHM) studying the Quaternary activity of the Colima Volcanic Complex in the west of Mexico
Constraining the nature and timescales of magmatic processes, which trigger volcanic eruptions is vital for understanding future eruptive behaviour. With an extensive effusive and explosive eruptive record, the Quaternary Colima Volcanic Complex (CVC) in Mexico is an ideal candidate to study such processes. Located in the western Trans-Mexican Volcanic Belt, the CVC is formed of the highly active Volcán de Colima, as well as extinct Nevado de Colima and El Cántaro edifices.
I conducted fieldwork in early 2018, sampling lava and tephra sequences. Seven Pleistocene lavas were collected from Nevado de Colima and 14 Holocene lavas from VdeC. 51 pumice and scoria samples from the late-Pleistocene to Holocene were also collected.
My research examines:
- The role played by alkaline magmas in initiating effusive and explosive activity
- The timescales these magmatic processes operate on
- How effusive to explosive transitions have developed over the Holocene
This work will determine the timescales of magmatic processes across an entire volcanic complex. Understanding how these magmatic processes operated in the past, will be a key part of informing future volcanic hazards.
