Meghan S. Miller is a Canadian geoscientist based in Australia, who studies the structural and dynamical evolution of the Earth. [1] She is a professor in the School of Earth Sciences at the Australian National University [1] and the program leader of the AuScope Earth Imaging & Sounding program. [2]
Miller was born in British Columbia, Canada, and grew up in Phoenix, Arizona. She started her studies in Southern California, and then moved to New York, where she completed a Master of Science degree at Columbia University and a Master in Engineering in Geophysics at Cornell University. [1] [3] In 2006, Miller was awarded a Doctor of Philosophy degree conferred by the Australian National University, and her research was focused on studying the Earth's mantle structures using geophysical imagery. [1] [3] [4]
From 2006 to 2008, Miller was a postdoctoral research associate at the University of British Columbia, Vancouver, Canada, and at Rice University in Texas, Houston. In 2009, she started working as an assistant professor at the University of Southern California. In 2015, she was promoted to associate professor with tenure at the same academic institution. In 2017, Miller moved to Australia to join the School of Earth Sciences at the Australian National University. She was promoted to full professor in January 2021. [1] [3]
Since 2017, Miller has led AuScope's Earth Imaging & Sounding Program, which aims to collect, process and provide geophysical datasets that allow end users to picture the subsurface of Australia. [2] Between 2016 and 2021, Miller was a member of the Board of Directors for the Seismological Society of America, specifically, she was part of the Diversity, Equity and Inclusion Committee and of the Honours Committee. [5]
Miller's research aims to understand the tectonic evolution of the Earth by using novel observational seismology techniques together with other geological and geophysical data. In particular, Miller investigates current subduction zones and cratons, such as Morocco, Indonesia, Timor Leste, Western Australia, Alaska and California, which provide insights into previous tectonic processes. [1] [6]
Miller is the leading author of two published articles in The Conversation. Her first article was published in 2020, with Louise Moresi as a co-author, discussing how COVID-19-related lockdowns in Australia allowed scientists to study minor earthquakes due to the decrease of noise and vibration produced by humans in motion. [7] Miller was interviewed by ABC News following the 2023 Sunbury earthquake. During this interview, she explained the causes of the aftershocks that occurred after this 4.0 moment magnitude scale tremor, and provided insights into the regions in Australia where earthquakes are more likely to occur.
In 2006, Miller was awarded a Postdoctoral Fellowship by the Natural Sciences and Engineering Research Council of Canada. [8] In 2011, Miller was awarded the Faculty Early Career Development (CAREER) Program, bestowed by the National Science Foundation of the United States government. [8] This program assists early-career faculty-members who show promise in becoming exemplary academic models in both research and education. [9]
In 2022, Miller started her Australian Research Council (ARC) Future Fellowship, focused on using Distributed acoustic sensing (DAS) to image with high-resolution the Earth's structure and to detect micro-seismicity. [1] [10]
Seismology is the scientific study of earthquakes and the generation and propagation of elastic waves through the Earth or other planetary bodies. It also includes studies of earthquake environmental effects such as tsunamis as well as diverse seismic sources such as volcanic, tectonic, glacial, fluvial, oceanic microseism, atmospheric, and artificial processes such as explosions and human activities. A related field that uses geology to infer information regarding past earthquakes is paleoseismology. A recording of Earth motion as a function of time, created by a seismograph is called a seismogram. A seismologist is a scientist works in basic or applied seismology.
Megathrust earthquakes occur at convergent plate boundaries, where one tectonic plate is forced underneath another. The earthquakes are caused by slip along the thrust fault that forms the contact between the two plates. These interplate earthquakes are the planet's most powerful, with moment magnitudes (Mw) that can exceed 9.0. Since 1900, all earthquakes of magnitude 9.0 or greater have been megathrust earthquakes.
The EarthScope project (2003-2018) was an National Science Foundation (NSF) funded earth science program that, from 2003-2018, used geological and geophysical techniques to explore the structure and evolution of the North American continent and to understand the processes controlling earthquakes and volcanoes. The project had three components: USArray, the Plate Boundary Observatory, and the San Andreas Fault Observatory at Depth. Organizations associated with the project included UNAVCO, the Incorporated Research Institutions for Seismology (IRIS), Stanford University, the United States Geological Survey (USGS) and National Aeronautics and Space Administration (NASA). Several international organizations also contributed to the initiative. EarthScope data are publicly accessible.

Clarence Roderic Allen was an American geologist who studied seismology.
Michael E. Wysession is a professor of Earth and Planetary Sciences at Washington University in St. Louis, and author of numerous science textbooks published by Pearson Education, Prentice Hall and the Savvas Learning Corporation. Wysession has made many contributions to geoscience education and literacy, including chairing the inclusion of Earth and space science in the U.S. National Academy of Science report A Framework for K-12 Science Education and the U.S. K-12 Next Generation Science Standards
Anya Marie Reading is a professor of Geophysics and Associate Head of Research in the School of Natural Sciences, University of Tasmania.
The 2016 Oklahoma earthquake occurred on September 3, 2016 near Pawnee, Oklahoma. Measuring 5.8 on the moment magnitude scale, it is the strongest in state history. At 5.8 magnitude, this ties it with the 2011 Virginia earthquake, which was determined after it struck to be the most powerful quake in the eastern United States in the preceding 70 years.
