James Gregory "Greg" Hirth (born June 4, 1963) is an American

geophysicist, specializing in tectonophysics.[1][2] He is known for his experiments in rock deformation and his applications of rheology in development of models for tectonophysics.[3]

Biography

Greg Hirth as a boy and teenager enjoyed the outdoors in the woods of Ohio and the mountains of Colorado.

Caltech (fall 1999), France's University of Montpellier (spring 2007), and Rice University (spring 2011).[2]

From 1993 to 2007, Hirth was a part-time research affiliate at Massachusetts Institute of Technology (MIT), as a participant in collaborative efforts in geophysics by WHOI and MIT. For the WHOI/MIT Joint Program, he was the leader for field trips in 1994 to Basin and Range National Monument, in 2001 to Yellowstone National Park and Snake River Plain, and in 2003 to Mount St. Helens and Puget Sound.[2]

Hirth has done

Cascade Mountains, in the region near Big Jim Mountain in the Chiwaukum Mountains, and in Trinity County, California. He has also done geological fieldwork in Central Australia (1993),[2] in the Talkeetna Arc (2000–2002),[6][7] in Norway (2009), and in California's Mecca Hills (2021). Hirth was on three research cruises to the Southwest Indian Ridge.[2]

From 2013 to 2015 Hirth was the president of the Tectonophysics Section of the American Geophysical Union. From 1997 to 1999 he served on the editorial board of the journal Geology. He was an associate editor from 1999 to 2002 for the Journal of Geophysical Research and from 2006 to 2010 for the journal Geochemistry, Geophysics, Geosystems (colloquially called G-cubed).[2]

Hirth's 1996 paper Water in the oceanic upper mantle: Implications for rheology, melt extraction and the evolution of the lithosphere, co-authored with David L. Kohlstedt,[8] has been cited more than 1750 times. Hirth is the author or co-author of more than 25 articles that have been cite more than 100 time each.[3] He has done research on earthquakes,[9][10][11][12] effects of melt and creep in the mantle on the rheology of the aggregate,[13][14][15] and the effects of grain size evolution on geophysical processes.[16][17][18] He and his colleagues have used experimental and theoretical rheology in constructing models of the oceanic lithosphere,[19][20] the Iceland hotspot[21] and several other geophysical phenomena.[3]

Hirth was elected in 2006 a Fellow of the Mineralogical Society of America and in 2008 a Fellow of the American Geophysical Union (AGU).[2] He gave the AGU's Francis Birch Lecture in 2017.[22] He received the George P. Woollard Award from the Geological Society of America (GSA) in 2018.[3]

His father, John Price Hirth, was elected in 1974 a member of the National Academy of Engineering and in 1994 a member of the National Academy of Sciences.[23][24] Greg Hirth married Ann E. Mulligan, whom he met at Brown University.[4] She graduated in 1988 from Brown University with an A.B. in geological sciences and in 1999 from the University of Connecticut with a Ph.D. in environmental engineering. She is a researcher employed at WHOI's Marine Policy Center.[25]
