Kyle R Anderson
Biography
Kyle is a research geophysicist for the U.S. Geological Survey at Moffett Field, California. Much of his work is focused on understanding volcanic systems using a combination of physics-based (multiphysical) volcano models and Bayesian statistics. This approach enables probabilistic constraint on properties of volcanic systems such as the composition and volume of stored magma, and can be used in some cases to forecast future eruptive activity.

The prevalence and significance of offset magma reservoirs at arc volcanoes
Determining the spatial relations between volcanic edifices and their underlying magma storage zones is fundamental for characterizing long-term evolution and short-term unrest. We compile centroid locations of upper crustal magma reservoirs at 56 arc volcanoes inferred from seismic, magnetotelluric, and geodetic studies. We show that magma...

Preliminary analyses of volcanic hazards at Kīlauea Volcano, Hawai‘i, 2017–2018
From 2017 to 2018, the U.S. Geological Survey (USGS) Hawaiian Volcano Observatory (HVO) responded to ongoing and changing eruptions at Kīlauea Volcano as part of its mission to monitor volcanic processes, issue warnings of dangerous activity, and assess volcanic hazards. To formalize short-term hazards assessments—and, in some cases, issue...
Neal, Christina A.; Anderson, Kyle R. Temporal variations in scrubbing of magmatic gases at the summit of Kīlauea Volcano, Hawai‘i
Measurements of gas compositions and emission rates play a major role in monitoring restless volcanoes. However, thermodynamic calculations imply that scrubbing by groundwater will prevent most HCl and significant SO2 emissions until dry pathways are established, thus leading to underestimates of gas released from magma and magma volumes. Despite...
Hurwitz, Shaul; Anderson, Kyle R. Cyclic lava effusion during the 2018 eruption of Kīlauea Volcano
Lava flows present a recurring threat to communities on active volcanoes, and volumetric eruption rate is one of the primary factors controlling flow behavior and hazard. The timescales and driving forces of eruption rate variability, however, remain poorly understood. In 2018, a highly destructive eruption occurred on the lower flank of Kīlauea...

Caldera-forming eruptions are among Earths most hazardous natural phenomena, yet the architecture of subcaldera magma reservoirs and the conditions that trigger collapse are poorly understood. Observations from the formation of a 0.8cubic kilometer basaltic caldera at Klauea Volcano in 2018 included the draining of an active lava lake, which...
Anderson, Kyle R.; Johanson, Ingrid; Patrick, Matthew R.; Gu, Mengyang; Segall, Paul; Poland, Michael P.; Montgomery-Brown, Emily; Miklius, Asta Partly cloudy with a chance of lava flows: Forecasting volcanic eruptions in the 21st century
A primary goal of volcanology is forecasting hazardous eruptive activity. Despite much progress over the last century, however, volcanoes still erupt with no detected precursors, lives and livelihoods are lost to eruptive activity, and forecasting the onsets of eruptions remains fraught with uncertainty. Long‐term forecasts are generally derived...
Poland, Michael P.; Anderson, Kyle R. Mechanics of inflationary deformation during Caldera collapse: Evidence from the 2018 Kīlauea Eruption
During the 2018 Kilauea eruption the caldera ffloor dropped 500 meters in 62 nearly periodic events of up to 8 meters. Caldera collapse maintains pressure in the magma reservoir necessary to sustain high-rate eruptions. The 2018 collapses were accompanied by inflationary tilts and displacements, similar to observations at other basaltic calderas....
Paul Segall; Anderson, Kyle R.; Johanson, Ingrid; Miklius, Asta Physicochemical models of effusive rhyolitic eruptions constrained with InSAR and DEM data: A case study of the 2011-2012 Cordon Caulle eruption
The 9 month long 2011-2012 eruption of Cordon Caulle (Southern Andes, Chile) is the best instrumentally recorded rhyolitic eruption to date and the first time that the effusion of a rhyolitic flow has been observed in detail. We use Interferometric Synthetic Aperture Radar (InSAR), with time-lapse DEMs and numerical models to study the dynamics of...
Francisco Delgado; Julia Kubanek; Anderson, Kyle R.; Paul Lundgren; Pritchard, Matthew E. A cautionary tale of topography and tilt from Kilauea Caldera
We conduct finite element analysis to investigate the effect of sharp topography on surface ground deformation caused by pressure changes in a magma reservoir. Tilt data express the horizontal gradient of vertical displacement and therefore can emphasize small variations in deformation that go unnoticed using other methods. We find that the...
Johnson, Jessica A.; Poland, Michael P.; Anderson, Kyle R.; Biggs, Juliet The 2018 rift eruption and summit collapse of Kilauea Volcano
In 2018, Kīlauea Volcano experienced its largest lower East Rift Zone (LERZ) eruption and caldera collapse in at least 200 years. After collapse of the Pu'u 'Ō'ō vent on 30 April, magma propagated downrift. Eruptive fissures opened in the LERZ on 3 May, eventually extending ~6.8 km. A 4 May earthquake (M6.9) produced ~5 m of fault slip. Lava...

Kīlauea Volcano is an archetype for the complex interactions that can occur between a volcano’s summit and flanks. Decades of monitoring at Kīlauea have demonstrated that magma rises beneath the summit and flows laterally at shallow depths to erupt along the rift zones. Kīlauea’s recent eruptions at Halema‘uma‘u and Pu‘u ‘Ō‘ō mark the first time...
Patrick, Matthew R.; Orr, Tim R.; Anderson, Kyle R.; Swanson, Don Decaying lava extrusion rate at El Reventador Volcano, Ecuador measured using high-resolution satellite radar
Lava extrusion at erupting volcanoes causes rapid changes in topography and morphology on the order of tens or even hundreds of meters. Satellite radar provides a method for measuring changes in topographic height over a given time period to an accuracy of meters, either by measuring the width of radar shadow cast by steep sided features, or by...
