Kyle R Anderson
Biography
I am a research geophysicist for the U.S. Geological Survey at Moffett Field, California. I work to understand volcanic systems by developing mathematical models which relate magma physics with monitoring data such as ground deformations and eruption rates. By comparing the models with real-world observations using probabilistic statistical approaches it is possible to 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. I've worked most extensively at Mount St. Helens and Kīlauea volcanoes, but I'm interested in volcanoes and eruptions around the world.

Repeating caldera collapse events constrain fault friction at the kilometer scale
Fault friction is central to understanding earthquakes, yet laboratory rock mechanics experiments are restricted to, at most, meter scale. Questions thus remain as to the applicability of measured frictional properties to faulting in situ. In particular, the slip-weakening distance dc">dcdc strongly influences precursory slip during...
Segall, Paul; Anderson, Kyle R. The cascading origin of the 2018 Kīlauea eruption and implications for future forecasting
The 2018 summit and flank eruption of Kīlauea Volcano was one of the largest volcanic events in Hawaiʻi in 200 years. Data suggest that a backup in the magma plumbing system at the long-lived Puʻu ʻŌʻō eruption site caused widespread pressurization in the volcano, driving magma into the lower flank. The eruption evolved, and its impact expanded,...

Throughout the 2018 eruption of Kīlauea volcano (Hawai‘i), episodic collapses of a portion of the volcano’s summit caldera produced repeated Mw">Mw 4.9–5.3 earthquakes. Each of these 62 events was characterized by a very‐long‐period (VLP) seismic signal (>40  s">>40 s). Although collapses in the...
Flinders, Ashton; Johanson, Ingrid; Dawson, Phillip B.; Anderson, Kyle R.; Haney, Matthew M.; Shiro, Brian Caldera collapse geometry revealed by near‐field GPS displacements at Kilauea Volcano in 2018
We employ near‐field GPS data to determine the subsurface geometry of a collapsing caldera during the 2018 Kīlauea eruption. Collapse occurred in 62 discrete events, with “inflationary” deformation external to the collapse, similar to previous basaltic collapses. We take advantage of GPS data from the collapsing block and independent constraints...
Segall, Paul; Anderson, Kyle R.; Pulvirenti, Fabio; Wang, Taiyi; Johanson, Ingrid 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....

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...
