Chapman

on Distributed Volcanism and Distributed Volcanic Hazards

16-20 March 2020 in Flagstaff, Arizona

Conference postponed

Dear Chapman Conference Attendee,

In order to ensure a healthy and safe meeting experience for our attendees in response to COVID-19, AGU and the conference chairs are postponing the conference until Fall 2020. We are looking at alternative dates in September.

We will be in touch soon with information on the new conference dates, registration (including refund process and options), abstract submissions and the post-conference field trip.

Thank you for your patience and understanding. We look forward to your continued support of the Chapman Conference.

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 to join us for three days of conference presentations and discussions that will be held March 16-18, 2020 at the USGS Astrogeology Science Center in Flagstaff, Arizona. 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 two-day field trip to the Springerville Volcanic Field that will be held March 19-20, 2020. Accommodations should not be reserved in Flagstaff for this portion of the meeting. We will travel 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.

Important Logistics for the Distributed Volcanism field trip, 19-20 March

Much more information about the geology of the Springerville volcanic field and about our road stops will be provided on the field trip. In advance of this, please be aware of this important logistical information concerning the post-meeting field trip.

Registration and fees

Only conference participants who register for the field trip will be allowed to participate.

We anticipate that the expenses for the field trip will be:

  • Lodging (same gender, shared room): $50
  • Lunch (two days): $30
  • Snacks and water: $10
  • Gas and related charges: $10
  • Total $100 USD

This does not cover your cost for dinner in Springerville, breakfast in Springerville, and other incidental expenses you might have.

After registration you will receive, by email, a request for a field trip deposit to cover the cost of your lodging in Springerville, lunch and related supplies during the field trip and gas ($100). If you prefer a room by yourself on the night of March 19 in Springerville, the deposit will be $135. Since we are running this field trip at cost, it is quite important to pay this deposit in advance of the field trip! Barring unforeseen circumstances, this is the total price of attending the field trip. Additional expenses on the trip include your meals (other than lunch), transportation after the end of the field trip, and incidentals.

General Schedule (field trip dates: March 19-20)

March 19 – leave Flagstaff and tour the southern Springerville volcanic field

We plan to leave the Astrogeology Building parking lot (location of the conference) at 8:00 AM on Thursday morning (March 19). It is about a 2 hour and 30 minute drive from Flagstaff to our first outcrop, near the town of Show Low (AZ).

Subsequent stops will take in various lava flow, scoria cone and related features as we work our way around the southern part of the volcanic field. Weather permitting, we should have spectacular views of the volcanic field and of the Mogollon Rim, the dramatic southern edge of the Colorado plateau.

Lunch will be provided on March 19 as part of the field trip. Be sure to let us know your dietary restrictions and/or preferences when you register for the field trip. Water will be provided but please bring your own water bottle!

On the evening of March 19 we will arrive in Springerville (AZ) and stay at Reed’s Motel. We will be on our own for dinner – but likely we will all be at the same restaurant since options are limited!

March 20 - leave Springerville and return to Flagstaff, Phoenix, or Springerville

We will leave the motel parking lot for the field promptly at 8:30 (breakfast is available across the street from the motel for those who want to grab breakfast beforehand). We will drive out of Springerville around the northern side of the volcanic field, stopping to investigate spectacular scoria cone alignments, vent structures, and domes.

Lunch will be provided on March 20 as part of the field trip. Water will be provided but please bring your own water bottle!

Our last stop of the day will be east of Show Low. We ask field trip participants to specify when they register if they are returning to Springerville (those leaving for Albuquerque the next day), returning to Flagstaff, or going on to Phoenix. We will make every attempt to accommodate these options at the end of the trip.

Weather and clothing

Usually, Springerville (AZ) experiences high temperatures of 60-70 F (15 – 20 C) and lows of 30-40 F (0-5 C) in March with sunny to partly cloudy skies. But, please be prepared for the unexpected as elevations are around 6000 ft (1800 m) and the weather is capable of extremes. It is possible we will experience a wet spring snow! Please bring cool weather gear (hat, gloves, wind gear) and rain gear just in case. A sun hat, sun glasses, lip balm and sun screen are essential. We recommend field boots.

Safety and Cultural Awareness

This field trip requires moderate walking away from the vehicles, including walking on lava flows and related rugged terrain for short distances. The elevation of the Springville volcanic field is around 1800 m (6000 ft) and it is not unusual for hikers to experience shortness of breath. Please be aware of your own limitations. If you have a medical condition, please consider if this might affect your participation when you register.

We will take precautions to ensure a safe field trip. Please be aware that some field trip stops are near two-lane highways. We ask all field trip participants to be aware of their surroundings and especially to be careful to avoid traffic on roadways.

We will not be able to transport alcohol in field-trip vehicles and consumption of alcohol in these vehicles or while we are in the field is expressly forbidden. Smoking is not allowed on the field trip.

Parts of the trip cross White Mountain Apache lands, Arizona Trust lands, and BLM land. Please treat the environment and those you encounter in it with respect.

Contact

If you have questions or concerns about the field trip, please contact Chuck Connor at [email protected].
