Gavin P Hayes
I am a seismologist and program coordinator with the USGS, based in in Golden, CO. I oversee the activities of the Earthquake Hazards, Geomagnetism, and Global Seismographic Network (GSN) Programs within the Natural Hazards Mission Area.
Gavin Hayes is the Senior Science Advisor for Earthquake and Geologic Hazards at USGS. In this position, he oversees the Earthquake Hazards, Geomagnetism, and Global Seismographic Network (GSN) Programs. Hayes joined the USGS in 2007, after receiving a doctoral degree in geosciences from Pennsylvania State University, and master’s and bachelor’s degrees from the University of Leeds in England. He was a post-doctoral scholar with the USGS National Earthquake Information Center before being hired permanently in 2012, and was a Research Geophysicist with that group from 2012-2020.
As part of the NEIC, Hayes helped to lead the USGS real time response to domestic and global earthquakes, rapidly characterizing the source properties of earthquakes, and interpreting events within their regional tectonic context. Hayes has over 80 publications in the areas of seismology, tectonics, geodesy and natural hazards, and in the applications of these subjects to earthquake safety, hazard and risk mitigation.

Seismicity of the Earth 1900–2010 Himalaya and vicinity
Seismicity in the Himalaya region predominantly results from the collision of the India and Eurasia continental plates, which are converging at a relative rate of 40–50 mm/yr. Northward underthrusting of India beneath Eurasia generates numerous earthquakes and consequently makes this area one of the most seismically hazardous regions on Earth. The surface expression of the plate boundary is markedAuthorsBethan Turner, Jennifer Jenkins, Rebecca Turner, Amy Parker, Alison Sinclair, Sian Davies, Gavin P. Hayes, Antonio Villaseñor, Rirchard L. Dart, Arthur C. Tarr, Kevin P. Furlong, Harley M. BenzSeismicity of the Earth 1900–2010 Middle East and vicinity
No fewer than four major tectonic plates (Arabia, Eurasia, India, and Africa) and one smaller tectonic block (Anatolia) are responsible for seismicity and tectonics in the Middle East and surrounding region. Geologic development of the region is a consequence of a number of first-order plate tectonic processes that include subduction, large-scale transform faulting, compressional mountain buildingAuthorsJennifer Jenkins, Bethan Turner, Rebecca Turner, Gavin P. Hayes, Sian Davies, Richard L. Dart, Arthur C. Tarr, Antonio Villaseñor, Harley M. BenzQuantifying potential earthquake and tsunami hazard in the Lesser Antilles subduction zone of the Caribbean region
In this study, we quantify the seismic and tsunami hazard in the Lesser Antilles subduction zone, focusing on the plate interface offshore of Guadeloupe. We compare potential strain accumulated via GPS-derived plate motions to strain release due to earthquakes that have occurred over the past 110 yr, and compute the resulting moment deficit. Our results suggest that enough strain is currently storAuthorsGavin P. Hayes, Daniel E. McNamara, Lily Seidman, Jean RogerW phase source inversion for moderate to large earthquakes (1990-2010)
Rapid characterization of the earthquake source and of its effects is a growing field of interest. Until recently, it still took several hours to determine the first-order attributes of a great earthquake (e.g. Mw≥ 7.5), even in a well-instrumented region. The main limiting factors were data saturation, the interference of different phases and the time duration and spatial extent of the source rupAuthorsZacharie Duputel, Luis Rivera, Hiroo Kanamori, Gavin P. HayesSlab1.0: A three-dimensional model of global subduction zone geometries
We describe and present a new model of global subduction zone geometries, called Slab1.0. An extension of previous efforts to constrain the two-dimensional non-planar geometry of subduction zones around the focus of large earthquakes, Slab1.0 describes the detailed, non-planar, three-dimensional geometry of approximately 85% of subduction zones worldwide. While the model focuses on the detailed foAuthorsGavin P. Hayes, David J. Wald, Rebecca L. JohnsonThe 25 October 2010 Mentawai tsunami earthquake, from real-time discriminants, finite-fault rupture, and tsunami excitation
The moment magnitude 7.8 earthquake that struck offshore the Mentawai islands in western Indonesia on 25 October 2010 created a locally large tsunami that caused more than 400 human causalities. We identify this earthquake as a rare slow‐source tsunami earthquake based on: 1) disproportionately large tsunami waves; 2) excessive rupture duration near 125 s; 3) predominantly shallow, near‐trench slAuthorsAndrew V. Newman, Gavin P. Hayes, Yong Wei, Jaime ConversSeismicity of the Earth 1900-2010 eastern margin of the Australia plate
The eastern margin of the Australia plate is one of the most seismically active areas of the world due to high rates of convergence between the Australia and Pacific plates. In the region of New Zealand, the 3,000 km long Australia-Pacific plate boundary extends from south of Macquarie Island to the southern Kermadec Island chain. It includes an oceanic transform (the Macquarie Ridge), two oppositAuthorsHarley M. Benz, Matthew Herman, Arthur C. Tarr, Gavin P. Hayes, Kevin P. Furlong, Antonio H. Villaseñor, Richard L. Dart, Susan RheaSeismicity of the Earth 1900-2010 New Guinea and vicinity
There have been 22 M7.5+ earthquakes recorded in the New Guinea region since 1900. The dominant earthquake mechanisms are thrust and strike slip, associated with the arc-continent collision and the relative motions between numerous local microplates. The largest earthquake in the region was a M8.2 shallow thrust fault event in the northern Papua province of Indonesia that killed 166 people in 1996AuthorsHarley M. Benz, Matthew Herman, Arthur C.

This map shows details of the Australia plate and vicinity not presented in Tarr and others (2010). The boundary of the Australia plate includes all fundamental plate boundary components: mid-ocean ridges, subduction zones, arc-continent collisions, and large-offset transform faults. Along the southern edge of the plate the mid-ocean ridge separates the Australia and Antarctica plates and its behaAuthorsHarley M. Benz, Matthew Herman, Arthur C. Tarr, Gavin P. Hayes, Kevin P. Furlong, Antonio H. Villaseñor, Richard L. Dart, Susan RheaSeismicity of the Earth 1900-2010 Mexico and vicinity
Mexico, located in one of the world's most seismically active regions, lies on three large tectonic plates: the North American plate, Pacific plate, and Cocos plate. The relative motion of these tectonic plates causes frequent earthquakes and active volcanism and mountain building. Mexico's most seismically active region is in southern Mexico where the Cocos plate is subducting northwestward beneaAuthorsSusan Rhea, Richard L. Dart, Antonio H. Villaseñor, Gavin P. Hayes, Arthur C. Tarr, Kevin P. Furlong, Harley M. BenzConstraints on the long‐period moment‐dip tradeoff for the Tohoku earthquake
Since the work of Kanamori and Given (1981), it has been recognized that shallow, pure dip‐slip earthquakes excite long‐period surface waves such that it is difficult to independently constrain the moment (M0) and the dip (δ) of the source mechanism, with only the product M0 sin(2δ) being well constrained. Because of this, it is often assumed that the primary discrepancies between the moments of sAuthorsVictor C. Tsai, Gavin P. Hayes, Zacharie DuputelRapid Source Characterization of the 2011 Mw 9.0 off the Pacific coast of Tohoku Earthquake
On March 11th, 2011, a moment magnitude 9.0 earthquake struck off the coast of northeast Honshu, Japan, generating what may well turn out to be the most costly natural disaster ever. In the hours following the event, the U.S. Geological Survey National Earthquake Information Center led a rapid response to characterize the earthquake in terms of its location, size, faulting source, shaking and slipAuthorsGavin P.
