Quantifying active volcanic processes and mitigating their hazards with HyspIRI data

Michael Ramsey, University of Pittsburgh"

Collaborators: Andy Harris (UBP, France), Matt Watson (UB, England), Matt Patrick (HVO)!

Objectives: •  Task 1:Quantify the magnitude of temperature-

dependent emissivity change for active basaltic surfaces using in situ field and laboratory IR data (fundamental science)

•  Task 2: Determine the accuracy of high-temperature emissivity extraction at potential HyspIRI spatial resolutions and its impact on modeling of flow advance (applied science)

10/2015"

Requirements and Constraints •  Start Date Preference: Fall 2016 or Spring 2017 •  Surface Elevation: 0 to ~ 4000 feet •  Weather Conditions: clear, no/low clouds •  Cloud Cover (Max): 10% •  Sun Angle Limits: not important •  Ground Condition: dry •  Satellite Overpass?: yes, Terra at ~ 11am/11pm LT •  Sea State/Tidal Cycle: n/a •  Additional requirements: coordination with field

team and HVO staff

Investigation Sites •  Locations: Big Island

of Hawaii with specific targets centered on the active lava locations 1.  lava lake at

Kilauea crater 2.  active flows in the

East Rift Zone

Approach •  The airborne data will be forward-modeled

using a quantitative resampling methodology. •  During the overflights, ground-based

multispectral TIR data will be acquired from a newly-developed instrument.

•  The combined data will be used to validate a correction approach for thermally-mixed HyspIRI data using VSWIR & TIR data.

•  Results will be input into flow modeling to better monitor and predict future volcanic hazardous phenomena.
