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.

Abstracts coming soon

Abstract submissions will open on 2 October 2019. Stay tuned.

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 two-day field trip from 19 – 20 March to the Zuni-Bandera, Quemado, and Springerville volcanic fields of Arizona and New Mexico.

The Zuni-Bandera volcanic field has a very young, large-volume lava flow [McCarty’s flow, dated at 3.2 ka by 14C and 3.9 ka by 36Cl, Dunbar and Lucas, 2005] and demonstrates the importance of determining lava-flow hazards and risks. Zuni Salt Lake is a large maar volcano in the Quemado volcanic field, south of Zuni-Bandera volcanic field, dated at 86 ka by Ar/Ar [Dunbar and Lucas, 2005] and 9.9-13.4 ka by 14C [Onken and Forman, 2017], which demonstrates that problem of inaccurate dates for volcanism in the intermountain west.

This well-exposed maar is mostly on Zuni land, to which access is generally denied, but the southern rim and a small portion of the crater is Bureau of Land Management land. This includes excellent exposures of the tuffs associated with the eruption and will be used to demonstrate the hazards associated with phreatomagmatism in an arid landscape. Finally, we will visit several of the scoria cones in the Springerville volcanic field, where we can see the hazards associated with basaltic pyroclastic activity and effusion of lavas, and where we will also discuss the control of tectonic inheritance on vent locations [Deng et al., 2017].

Present your research on distributed volcanism and distributed volcanic hazards.

Opening soon

Format and schedule

The meeting will be held 16 – 18 March, followed by an optional two-day field trip from 19 – 20 March. The meeting will be comprised of oral and poster sessions, breakout sessions, and summary discussions.  
  • 1
    The first day will include introductions and ten talks by keynote speakers. The intent of these talks is to highlight the science and current challenges, setting the stage for the remainder of the workshop.
  • 2
    The second day will start with five breakout sessions. These working groups will identify the core science issues that we need to resolve to improve hazard forecasts. Each group will produce a summary of the state-of-the-science and science goals.
  • 3
    The third day will include talks, posters, and summary discussion, incorporating insights from the break-out groups and shifting the discussion to community response and planning.

Abstract submission policies 

Abstract submissions will open on 2 October and close on 20 November. You are not required to be an AGU member to submit an abstract. There is no fee for submissions.

Abstracts must focus on scientific results or their application. The Program Committee may decline abstracts with other focuses.

By submitting an abstract, you are obligated to give a presentation in the designated manner assigned by the Program Committee. Your submission also grants AGU permission to publish the abstract.

You cannot request oral presentations, although you may request a poster presentation.

Abstract submission guidelines

Abstracts must meet the following guidelines to be considered for the Chapman Conference. 
  • 1
    Your abstract title should be no more than 300 characters and the abstract text must be less than 2000 characters. The character limit includes punctuation, but not spacing.
  • 2
    In lieu of adding the names of individual team members, you may reference a research team may be referenced in the ‘Title of Team’ field during the submission process.
  • 3
    You may add one table or image to your submission. If you would like to include multiple images, you must combine the images and save them as one file. We prefer image files be .jpg, however, .png, and .gif are also supported file types.
  • 4
    Submissions can be submitted and edited at any time up until 20 November.
