Kyle R Anderson
Biography
I am a research geophysicist for the U.S. Geological Survey in Menlo Park, California. Previously, I was a Mendenhall Postdoctoral Research Fellow at the Hawaiian Volcano Observatory. Much of my work is focused on understanding volcanic systems using a combination of physics-based (multiphysical) volcano models and Bayesian statistics. The models I develop relate magma physics with diverse types of observations including ground deformation, eruption rate, and gas emissions. Performing Bayesian inverse analysis using these models together with data from real volcanoes, I probabilistically constrain properties of volcanic systems such as the composition and volume of stored magma. This approach can also be used in some cases to forecast future eruptive activity.

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; Matthew Pritchard 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...

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...

Physics-based models of volcanic eruptions track conduit processes as functions of depth and time. When used in inversions, these models permit integration of diverse geological and geophysical data sets to constrain important parameters of magmatic systems. We develop a 1-D steady state conduit model for effusive eruptions including equilibrium...
Wong, Ying-Qi; Segall, Paul; Bradley, Andrew; Anderson, Kyle R. Abundant carbon in the mantle beneath Hawai`i
Estimates of carbon concentrations in Earth’s mantle vary over more than an order of magnitude, hindering our ability to understand mantle structure and mineralogy, partial melting, and the carbon cycle. CO2 concentrations in mantle-derived magmas supplying hotspot ocean island volcanoes yield our most direct constraints on mantle carbon, but...

The 2014 annual report for the Hawaiian Volcano Observatory
Introduction This report summarizes team activities and findings of the Hawaiian Volcano Observatory during the year 2014 in geology, geodesy, seismicity, and gas geochemistry. The eruption of Pu‘u ‘Ō‘ō continued into its 32nd year with flows active to the northeast of the vent. One of them, the June 27th lava flow, named for the...

Estimating rates of magma supply to the world's volcanoes remains one of the most fundamental aims of volcanology. Yet, supply rates can be difficult to estimate even at well-monitored volcanoes, in part because observations are noisy and are usually considered independently rather than as part of a holistic system. In this work we demonstrate a...
Anderson, Kyle R.; Poland, Michael P. The 2014-2015 Pāhoa lava flow crisis at Kīlauea Volcano, Hawai‘i: Disaster avoided and lessons learned
Lava flow crises are nothing new on the Island of Hawai‘i, where their destructive force has been demonstrated repeatedly over the past several hundred years. The 2014–2015 Pāhoa lava flow crisis, however, was unique in terms of its societal impact and volcanological characteristics. Despite low effusion rates, a long-lived lava flow...

Jane; Thelen, Weston A.; Tollett, Willam; Trusdell, Frank A. Lava lake level as a gauge of magma reservoir pressure and eruptive hazard
Forecasting volcanic activity relies fundamentally on tracking magma pressure through the use of proxies, such as ground surface deformation and earthquake rates. Lava lakes at open-vent basaltic volcanoes provide a window into the uppermost magma system for gauging reservoir pressure changes more directly. At Kīlauea Volcano (Hawaiʻi, USA) the...

The 2004–2008 dome-building eruption at Mount St. Helens ended during winter 2007–2008 at a time when field observations were hampered by persistent bad weather. As a result, recognizing the end of the eruption was challenging—but important for scientists trying to understand how and why long-lived eruptions end and for public...

Episodic variations in magma pressures and flow rates at Kīlauea Volcano, defined by a characteristic temporal evolution and termed deflation-inflation (DI) events, have been observed since at least the 1990s. DI events consist of transient, days-long deflations and subsequent reinflations of the summit region, accompanied since 2008 by...
