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.

Constraints 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 sAuthorsV.C. Tsai, Gavin P. Hayes, Z. Duputel88 hours: The U.S. Geological Survey National Earthquake Information Center response to the March 11, 2011 Mw 9.0 Tohoku earthquake
The M 9.0 11 March 2011 Tohoku, Japan, earthquake and associated tsunami near the east coast of the island of Honshu caused tens of thousands of deaths and potentially over one trillion dollars in damage, resulting in one of the worst natural disasters ever recorded.

The South American arc extends over 7,000 km, from the Chilean triple junction offshore of southern Chile to its intersection with the Panama fracture zone, offshore the southern coast of Panama in Central America. It marks the plate boundary between the subducting Nazca plate and the South America plate, where the oceanic crust and lithosphere of the Nazca plate begin their decent into the mantleAuthorsSusan Rhea, Gavin P.

This map shows details of Japan and vicinity not visible in an earlier publication, U.S. Geological Survey Scientific Investigations Map 3064. Japan and its island possessions lie across four major tectonic plates: Pacific plate, North America plate; Eurasia plate; and Philippine Sea plate.

This map shows details of the Kuril-Kamchatka arc not visible in an earlier publication, U.S. Geological Survey Scientific Investigations Map 3064. The arc extends about 2,100 km from Hokkaido, Japan, along the Kuril Islands and the pacific coast of the Kamchatka, Russia, peninsula to its intersection with the Aleutian arc near the Commander Islands, Russia.

This map shows details of the Aleutian arc not visible in an earlier publication. The Aleutian arc extends about 3,000 km from the Gulf of Alaska to the Kamchatka Peninsula. It marks the region where the Pacific plate subducts into the mantle beneath the North America plate. This subduction is responsible for the generation of the Aleutian Islands and the deep offshore Aleutian Trench. Relative toAuthorsHarley M. Benz, Matthew Herman, Arthur C. Tarr, Gavin P.
