Chapman

on Distributed Volcanism and Distributed Volcanic Hazards

16-20 March 2020 in Flagstaff, Arizona

About the Chapman

Most subaerial volcanoes are found in widely distributed volcanic fields made up of tens to hundreds of vents. Eruption styles and potential impacts also vary. Explosive activity ranges from mild Strombolian and ash-producing eruptions that produce localized tephra fall to more explosive eruptions that result in widespread ashfall. Effusive eruptions can produce far-reaching lava flows, and non-eruptive open-vent outgassing degrades downwind air quality. Many distributed fields on Earth are poorly instrumented and their eruptive histories are not well understood, which limits our ability to forecast the potential location, timing and magnitude of future eruptions.

The purpose of this Chapman is to bring together scientists to discuss, develop, and test conceptual models of distributed volcanism. Focus by the scientific community is especially important now because of continuing growth of cities, communities, and critical infrastructure within sparsely monitored volcanic fields.

Who should attend?

We invite participants from all disciplines. We especially encourage participants from emergency management, geologic mapping, geochronology, physical volcanology, geomorphology, seismology, geodesy, geochemistry, exploration geophysics, hazards assessment, science communication, and related fields to attend.

Field trip

Join us for an optional field trip on the 19 - 20 March to the 3000 km2, Plio-Pliestocene Springerville volcanic field, the southernmost of the Colorado Plateau-edge dispersive fields, in east-central Arizona (Condit, 1991, Condit et al., 1989b, 1999). We will examine key stratigraphic relations of the 501 units of the field, and discuss the magmatic mapping (Condit, 2007) techniques applied by the five mappers to unravel the eruptive timing and source location of the 451 vents, and to characterize the petrologic and geophysical properties of the lavas of the field (Condit et al., 1989a, Mnich and Condit, 2018). Weather and access permitting, we will visit one of the best exposed of the field’s five maar craters, look at an example of one of the four fissure vents and one of the field’s two shield volcanoes. We will also visit numerous neotectonic features, including faulted flows and post-flow reversal of flow topography features documented by Crumpler et al., 1989, 1994, examine outcrops supporting the volcanic hazard assessments of Mnich and Condit, 2018, several scoria cones, and also discuss the recurrence rate of volcanism in the field (Condit and Connor, 1996), and the control of tectonic inheritance on vent locations (Deng et al., 2017). Time, weather, and logistics permitting we’d like to visit Greens Peak, at 3080m elevation, the highest point in the field, from which many of the features can be viewed.
