Mary Lou Zoback(néeChetlain; born July 5, 1952) is an Americangeophysicistandseismologist.A specialist in tectonic stress and natural hazards risks, she spent most of her career as a research scientist with theUnited States Geological Survey.Zoback chaired the World Stress Map project of the International Lithosphere Program from 1986 to 1992. Zoback served on the U.S.Nuclear Waste Technical Review Boardfrom 2012 to 2018.

Early life and education

[edit]

Mary Lou Chetlain was born on July 5, 1952, inSanford, Florida.[1]Her father Kent Chetlain was a sports editor with theBradenton Heraldand as a teenager, she operated theMcKechnie Fieldelectronic scoreboard duringPittsburgh Piratesspring training games.[2]

She began her undergraduate studies inoceanographyat theFlorida Institute of Technology.After taking a course onplate tectonicsand elasticity, she met geophysicistAllan V. Coxat a meeting on solar magnetism inCape Canaveral.Following his recommendation, she transferred toStanford Universityin her junior year, receiving a full scholarship.[3][1]At Stanford she earned a bachelor of science degree in 1974, a master of science degree in 1975, and a Ph.D. in 1978, all in geophysics.[4][1]Her doctoral thesis was titled "Mid-miocene rifting in north-central Nevada: A detailed study of late cenozoic deformation in the northern basin and range".[5]Her advisor wasGeorge Thompson.[3][6]

Career

[edit]

Following her graduation, Zoback conducted postdoctoral research from 1978 to 1979 with theUnited States Geological Survey(USGS) through aNational Research Councilfellowship.[4]She worked with the Heat Flow Studies group, conducting research on tectonic deformation in northern Nevada. In 1979, she joined the USGS as a research geophysicist in the office of the Western Earthquake Hazards Team.[1]

Zoback created a map of tectonic stress fields for the Western U.S. states, later extending the map with colleagues to include the contiguous United States. According to Zoback, the work demonstrated "that broad regions of the Earth’s crust in the U.S. were subjected to a uniformly oriented stress field and resulted from large-scale tectonic processes". Zoback was approached by the president of the International Lithosphere Program with the idea of creating a global map for stress fields.[3]

From 1986 to 1992, Zoback chaired the International Lithosphere Program's World Stress Map project, an open-access public database.[1]The project had the objective of inferring the relative magnitudes of forces that act on thelithosphere.Zoback coordinated the compilation and interpretation of geophysical and geologic data on tectonic stress fields with dozens of scientists from over 30 countries. The project led to a special issue of theJournal of Geophysical Researchin 1992 for which Zoback was guest editor.

Zoback was a member of theNational Research Council's United States Geodynamics Committee from 1985 to 1989.[1]and theNSFreview panel for the continental dynamics program. She is a past member of the council and executive board of theGeological Society of America(GSA)[7]and she served as president of the GSA's Tectonophysics Section in 2000.[1]

In 1990 Zoback received a Gilbert Fellowship Award from the USGS for a yearlong sabbatical inKarlsruhe, Germany.[1]

Zoback was the chief scientist of the USGS Earthquake Hazards team beginning in 1999. She oversaw the study "Earthquake Probabilities in the San Francisco Bay Region, 2002-2031". She was a USGS Senior Research Scientist from 2002 to 2006 and developed an integrated hazards research program for Northern California.

From 2006 to 2011, Zoback served as Vice President for Earthquake Risk Applications with Risk Management Solutions, a Bay Area catastrophe modeling firm. She developed risk models to examine the role thatearthquake insurancehas in society and to quantify the effects of risk reduction and disaster management.[8]

At Stanford University, she was a consulting professor in the Geophysics Department starting in 2011.[8]

Zoback was appointed to the U.S.Nuclear Waste Technical Review Boardby PresidentBarack Obamaon September 25, 2012.[9][10]The board provides scientific and technical oversight of the Department of Energy's program for managing and disposing of high-level nuclear waste and spent nuclear fuel.[11]

Research

[edit]

Zoback's principal area of research is activetectonics,[1]with an emphasis on the relationship between tectonic stress fields and the incidence of earthquakes. Her studies have focused on theSan Andreas Faultsystem, theBasin and Range Province,and intraplate regions. Her work has involved quantifyingnatural hazardrisks as well as developing strategies for risk reduction and metrics for disaster resilience.

Zoback dedicated a large part of her studies to theSan Andreas Faultsystem from 1986 to 1992. She worked on the connection between earthquakes andlarge strike-slip faults.[12]Through a reanalysis of the1906 San Francisco earthquake,Zoback studied the concept of theearthquake cycle.[13]

Personal life

[edit]

Zoback married geophysicistMark David Zobackin 1973. They have two children.[1]
