Earthquake experts gather to celebrate pioneer's 70th birthday

11/16/04

RENO, Nev. -- Seismology pioneer and University of Nevada, Reno Foundation Professor James Brune will be celebrating his 70th birthday with some of the world's leading earthquake experts this week.

"The best birthday present anyone could give Jim is to challenge him scientifically," said John Anderson, University professor of geophysics and director of the Nevada Seismological Laboratory. "That is exactly what we plan to do, present him with new, exciting science."

This Thursday and Friday, Brune will be surrounded by more than 40 former students and co-authors who will present him with their most recent research results in seismology.

"Jim has been a mentor and a colleague to many of the brightest minds in this field," said Rasool Anooshehpoor, University associate research professor of seismology and one of Brune's closest research partners.

"This is a gathering of the highest caliber of seismology scientists and I thoroughly expect some of them to go home inspired with new research ideas," added Anderson. "That always happens when people get together with Jim."

The birthday science symposium attendees are traveling from all over the globe to be at the University for this event. Five scientists are coming from Mexico where Brune has initiated a research network with Mexican seismologists for more than 35 years. Other international researchers making the trip hail from England, New Zealand and Switzerland. Brune's first student, Paul Richards, who co-authored the preeminent text on analytic theory and methods in seismology, "Quantitative Seismology," will be present along with members of the United States Geological Survey and the National Academy of Sciences.

Besides the obvious milestone being celebrated this week, Brune will also be honored for the more than 200 publications he has contributed over the past 45 years. According to Ralph Archuleta, one of Brune's former students and professor at the University of California at Santa Barbara, these publications reflect one of the hallmarks of Brune's science: collaboration.

Throughout his career, Brune has authored papers with more than 150 students and colleagues. He is often identified by his famous 1970 paper, "Tectonic Stress and the Spectra of Seismic Shear Waves from Earthquakes." This publication has been cited so often that it was named a "Citation Classic" in 1987.

In 1997 Brune received the Medal of the Seismological Society of America, the highest honor in his field. He earned a bachelor's degree in geological engineering from the University of Nevada, Reno in 1956 and his Ph.D. from Columbia University in 1961.

"This is an opportunity for experts and friends to come celebrate Jim's fundamental contributions in seismology and his extraordinary intuitive approach to science," said Anderson.
