Ecosphere, Volume 13, Issue 3, March 2022., 2022 Abstract Global warming is expected to affect movement‐related thermoregulation in ectotherms, but the likely effects on thermoconforming lizards, which spend little energy in thermoregulation behavior, are unclear. We used the Guatemalan beaded lizard (Heloderma charlesbogerti) as a model thermoconforming species to investigate the effects of ambient ...

The Extended Continental Crust West of Islas Marías (Mexico)
Frontiers in Earth Science, 2021 The crustal structure around the Islas Marías Archipelago has been debated for a long time. An important unresolved question is where the Rivera-North American plate subduction ends and the Tamayo fracture zone begins, from SE to NW.

Analyzing Explosive Volcanic Deposits From Satellite‐Based Radar Backscatter, Volcán de Fuego, 2018
Journal of Geophysical Research: Solid Earth, Volume 126, Issue 9, September 2021., 2021 Abstract Satellite radar backscatter has the potential to provide useful information about the progression of volcanic eruptions when optical, ground‐based, or radar phase‐based measurements are limited. However, backscatter changes are complex and challenging to interpret: explosive deposits produce different signals depending on pre‐existing ground ...

Moho Depth of Northern Baja California, Mexico, From Teleseismic Receiver Functions
Earth and Space Science, Volume 8, Issue 6, June 2021., 2021 Abstract We estimated Moho depths from data recorded by permanent and temporary broadband seismic stations deployed in northern Baja California, Mexico, using the receiver function technique. This region is composed of two subregions of contrasting geological and topographical characteristics: the Peninsular Ranges of Baja California (PRBC), a ...

Thermal Weakening Friction During Seismic Slip: Experiments and Models With Heat Sources and Sinks
Journal of Geophysical Research: Solid Earth, Volume 126, Issue 5, May 2021., 2021 Abstract Experiments that systematically explore rock friction under crustal earthquake conditions reveal that faults undergo abrupt dynamic weakening. Processes related to heating and weakening of fault surfaces have been invoked to explain pronounced velocity weakening.
