Matt M. Haney
I am a volcano seismologist at the Alaska Volcano Observatory (AVO) in Anchorage. My work involves research on the seismicity and structure of Alaskan volcanoes, volcano monitoring, infrasound, and the acquisition and processing of data from the AVO seismic network.
At AVO, I focus on the interpretation of seismicity at volcanoes with the goal of providing improved forecasts and assessments of volcano hazards to the public. Different aspects of my position touch on research, operations, and monitoring. A major part of my research includes the interpretation of seismic waves in the Earth and sound waves in the atmosphere for detecting volcanic unrest, imaging volcanic structure, and elucidating the dynamics of volcanic sources.

Non-perturbational surface-wave inversion: A Dix-type relation for surface waves Non-perturbational surface-wave inversion: A Dix-type relation for surface waves
We extend the approach underlying the well-known Dix equation in reflection seismology to surface waves. Within the context of surface wave inversion, the Dix-type relation we derive for surface waves allows accurate depth profiles of shear-wave velocity to be constructed directly from phase velocity data, in contrast to perturbational methods. The depth profiles can subsequently be used...

The 2013 eruption of Pavlof Volcano, Alaska: a spatter eruption at an ice- and snow-clad volcano The 2013 eruption of Pavlof Volcano, Alaska: a spatter eruption at an ice- and snow-clad volcano
The 2013 eruption of Pavlof Volcano, Alaska began on 13 May and ended 49 days later on 1 July. The eruption was characterized by persistent lava fountaining from a vent just north of the summit, intermittent strombolian explosions, and ash, gas, and aerosol plumes that reached as high as 8 km above sea level and on several occasions extended as much as 500 km downwind of the volcano...

Shaking up volcanoes Shaking up volcanoes
Most volcanic eruptions that occur shortly after a large distant earthquake do so by random chance. A few compelling cases for earthquake-triggered eruptions exist, particularly within 200 km of the earthquake, but this phenomenon is rare in part because volcanoes must be poised to erupt in order to be triggered by an earthquake (1). Large earthquakes often perturb volcanoes in more...

Surface‐wave Green’s tensors in the near field Surface‐wave Green’s tensors in the near field
We demonstrate the connection between theoretical expressions for the correlation of ambient noise Rayleigh and Love waves and the exact surface‐wave Green’s tensors for a point force. The surface‐wave Green’s tensors are well known in the far‐field limit. On the other hand, the imaginary part of the exact Green’s tensors, including near‐field effects, arises in correlation techniques...

Backprojection of volcanic tremor Backprojection of volcanic tremor
Backprojection has become a powerful tool for imaging the rupture process of global earthquakes. We demonstrate the ability of backprojection to illuminate and track volcanic sources as well. We apply the method to the seismic network from Okmok Volcano, Alaska, at the time of an escalation in tremor during the 2008 eruption. Although we are able to focus the wavefield close to the...

Distinguishing high surf from volcanic long-period earthquakes Distinguishing high surf from volcanic long-period earthquakes
Repeating long-period (LP) earthquakes are observed at active volcanoes worldwide and are typically attributed to unsteady pressure fluctuations associated with fluid migration through the volcanic plumbing system. Nonvolcanic sources of LP signals include ice movement and glacial outburst floods, and the waveform characteristics and frequency content of these events often make them...

Tracking changes in volcanic systems with seismic Interferometry Tracking changes in volcanic systems with seismic Interferometry
The detection and evaluation of time-dependent changes at volcanoes form the foundation upon which successful volcano monitoring is built. Temporal changes at volcanoes occur over all time scales and may be obvious (e.g., earthquake swarms) or subtle (e.g., a slow, steady increase in the level of tremor). Some of the most challenging types of time-dependent change to detect are subtle...

Catalog of earthquake hypocenters at Alaskan volcanoes: January 1 through December 31, 2012 Catalog of earthquake hypocenters at Alaskan volcanoes: January 1 through December 31, 2012
Between January 1 and December 31, 2012, the Alaska Volcano Observatory located 4,787 earthquakes, of which 4,211 occurred within 20 kilometers of the 33 volcanoes monitored by a seismograph network. There was significant seismic activity at Iliamna, Kanaga, and Little Sitkin volcanoes in 2012. Instrumentation highlights for this year include the implementation of the Advanced National...

Seismic observations of Redoubt Volcano, Alaska - 1989-2010 and a conceptual model of the Redoubt magmatic system Seismic observations of Redoubt Volcano, Alaska - 1989-2010 and a conceptual model of the Redoubt magmatic system
Seismic activity at Redoubt Volcano, Alaska, has been closely monitored since 1989 by a network of five to ten seismometers within 22 km of the volcano's summit. Major eruptions occurred in 1989-1990 and 2009 and were characterized by large volcanic explosions, episodes of lava dome growth and failure, pyroclastic flows, and lahars. Seismic features of the 1989-1990 eruption were 1) weak

Source characterization for an explosion during the 2009 eruption of Redoubt Volcano from very-long-period seismic waves Source characterization for an explosion during the 2009 eruption of Redoubt Volcano from very-long-period seismic waves
The 2009 eruption of Redoubt produced several very-long-period (VLP) signals associated with explosions. We invert for the source location and mechanism of an explosion at Redoubt volcano using waveform methods applied to broadband recordings. Such characterization of the source carries information on the geometry of the conduit and the physics of the explosion process. Inversions are...

Ambient seismic noise interferometry in Hawai'i reveals long-range observability of volcanic tremor Ambient seismic noise interferometry in Hawai'i reveals long-range observability of volcanic tremor
The use of seismic noise interferometry to retrieve Green's functions and the analysis of volcanic tremor are both useful in studying volcano dynamics. Whereas seismic noise interferometry allows long-range extraction of interpretable signals from a relatively weak noise wavefield, the characterization of volcanic tremor often requires a dense seismic array close to the source. We here...

Extension of the spatial autocorrelation (SPAC) method to mixed-component correlations of surface waves Extension of the spatial autocorrelation (SPAC) method to mixed-component correlations of surface waves
Using ambient seismic noise for imaging subsurface structure dates back to the development of the spatial autocorrelation (SPAC) method in the 1950s. We present a theoretical analysis of the SPAC method for multicomponent recordings of surface waves to determine the complete 3 × 3 matrix of correlations between all pairs of three-component motions, called the correlation matrix. In the...
