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.

Application of an updated atmospheric model to explore volcano infrasound propagation and detection in Alaska Application of an updated atmospheric model to explore volcano infrasound propagation and detection in Alaska
Winds and temperature gradients greatly affect the long-range propagation of infrasound. The spatio-temporal variability of these parameters must therefore be accurately characterized to correctly interpret recorded infrasound at long distances, specifically to differentiate between source and propagation effects. Here we present the first results of an open source reanalysis model...

The 2014 eruptions of Pavlof Volcano, Alaska The 2014 eruptions of Pavlof Volcano, Alaska
Pavlof Volcano is one of the most frequently active volcanoes in the Aleutian Island arc, having erupted more than 40 times since observations were first recorded in the early 1800s . The volcano is located on the Alaska Peninsula (lat 55.4173° N, long 161.8937° W), near Izembek National Wildlife Refuge. The towns and villages closest to the volcano are Cold Bay, Nelson Lagoon, Sand...

Reducing risk where tectonic plates collide—U.S. Geological Survey subduction zone science plan Reducing risk where tectonic plates collide—U.S. Geological Survey subduction zone science plan
The U.S. Geological Survey (USGS) serves the Nation by providing reliable scientific information and tools to build resilience in communities exposed to subduction zone earthquakes, tsunamis, landslides, and volcanic eruptions. Improving the application of USGS science to successfully reduce risk from these events relies on whole community efforts, with continuing partnerships among...

Perturbational and nonperturbational inversion of Rayleigh-wave velocities Perturbational and nonperturbational inversion of Rayleigh-wave velocities
The inversion of Rayleigh-wave dispersion curves is a classic geophysical inverse problem. We have developed a set of MATLAB codes that performs forward modeling and inversion of Rayleigh-wave phase or group velocity measurements. We describe two different methods of inversion: a perturbational method based on finite elements and a nonperturbational method based on the recently developed...

Seismic envelope-based detection and location of ground-coupled airwaves from volcanoes in Alaska Seismic envelope-based detection and location of ground-coupled airwaves from volcanoes in Alaska
Volcanic explosions and other infrasonic sources frequently produce acoustic waves that are recorded by seismometers. Here we explore multiple techniques to detect, locate, and characterize ground‐coupled airwaves (GCA) on volcano seismic networks in Alaska. GCA waveforms are typically incoherent between stations, thus we use envelope‐based techniques in our analyses. For distant sources...

Volcano deformation source parameters estimated from InSAR: Sensitivities to uncertainties in seismic tomography Volcano deformation source parameters estimated from InSAR: Sensitivities to uncertainties in seismic tomography
The eruption cycle of a volcano is controlled in part by the upward migration of magma. The characteristics of the magma flux produce a deformation signature at the Earth's surface. Inverse analyses use geodetic data to estimate strategic controlling parameters that describe the position and pressurization of a magma chamber at depth. The specific distribution of material properties...

Erratum to Surface‐wave green’s tensors in the near field Erratum to Surface‐wave green’s tensors in the near field
Haney and Nakahara (2014) derived expressions for surface‐wave Green’s tensors that included near‐field behavior. Building on the result for a force source, Haney and Nakahara (2014) further derived expressions for a general point moment tensor source using the exact Green’s tensors. However, it has come to our attention that, although the Green’s tensors were correct, the resulting...

Long period seismicity and very long period infrasound driven by shallow magmatic degassing at Mount Pagan, Mariana Islands Long period seismicity and very long period infrasound driven by shallow magmatic degassing at Mount Pagan, Mariana Islands
Long period (LP) seismicity and very long period infrasound (iVLP) were recorded during continuous degassing from Mount Pagan, Mariana Islands, in July 2013 to January 2014. The frequency content of the LP and iVLP events and delay times between the two arrivals were remarkably stable and indicate nearly co-located sources. Using phase-weighted stacking over similar events to dampen...

Monitoring changes in seismic velocity related to an ongoing rapid inflation event at Okmok volcano, Alaska Monitoring changes in seismic velocity related to an ongoing rapid inflation event at Okmok volcano, Alaska
Okmok is one of the most active volcanoes in the Aleutian Arc. In an effort to improve our ability to detect precursory activity leading to eruption at Okmok, we monitor a recent, and possibly ongoing, GPS-inferred rapid inflation event at the volcano using ambient noise interferometry (ANI). Applying this method, we identify changes in seismic velocity outside of Okmok’s caldera, which...

Source mechanism of small long-period events at Mount St. Helens in July 2005 using template matching, phase-weighted stacking, and full-waveform inversion Source mechanism of small long-period events at Mount St. Helens in July 2005 using template matching, phase-weighted stacking, and full-waveform inversion
Long-period (LP, 0.5-5 Hz) seismicity, observed at volcanoes worldwide, is a recognized signature of unrest and eruption. Cyclic LP “drumbeating” was the characteristic seismicity accompanying the sustained dome-building phase of the 2004–2008 eruption of Mount St. Helens (MSH), WA. However, together with the LP drumbeating was a near-continuous, randomly occurring series of tiny LP...

Point spread functions for earthquake source imaging: An interpretation based on seismic interferometry Point spread functions for earthquake source imaging: An interpretation based on seismic interferometry
Recently, various methods have been proposed and applied for earthquake source imaging, and theoretical relationships among the methods have been studied. In this study, we make a follow-up theoretical study to better understand the meanings of earthquake source imaging. For imaging problems, the point spread function (PSF) is used to describe the degree of blurring and degradation in an...

A comparison of methods to estimate seismic phase delays--Numerical examples for coda wave interferometry A comparison of methods to estimate seismic phase delays--Numerical examples for coda wave interferometry
Time-shift estimation between arrivals in two seismic traces before and after a velocity perturbation is a crucial step in many seismic methods. The accuracy of the estimated velocity perturbation location and amplitude depend on this time shift. Windowed cross correlation and trace stretching are two techniques commonly used to estimate local time shifts in seismic signals. In the work...
