Microseismicity and Large Earthquakes
Nadia Lapusta, Professor of Mechanical Engineering and Geophysics, and Caltech alumnus Dr. Junle Jiang, have linked the patterns of microseismicity to the depth extension of large earthquakes, both through modeling and observationally. They argue that fault segments which do not have concentrated microseismicity at the bottom of the seismogenic zone must have had deeper, larger earthquakes than currently believed. A number of segments on the San Andreas fault appear to fall into that category. The potential for such deeper earthquakes in the future would imply higher seismic hazard.

2016 Caltech Distinguished Alumni
Caltech has recognized two Engineering and Applied Science (EAS) graduates with the Distinguished Alumni Award, the highest honor regularly bestowed by the Institute. They are Carl V. Larson (BS '52, ME) and Thomas J. "Tim" Litle IV (BS '62, EAS). Larson is being recognized for his accomplished career in the electronics industry. Over the course of three decades, Larson has held numerous and diverse leadership roles in fields ranging from engineering to marketing. He is also being celebrated for his sustained commitment to the research, students, and alumni of Caltech. Litle is being recognized for his revolutionary contributions to commerce. Through innovations such as the presorted mail program he developed for the U.S. Postal Service and the three-digit security codes on credit cards, Litle has made global business more efficient and secure.

GALCIT Alumnus Allen E. Puckett Passes Away
Allen E. Puckett (PhD ’49 Aeronautics), pioneering aerospace engineer and chairman emeritus of Hughes Aircraft Co., passed away on March 31, 2014. He was one of the engineers who made Hughes Aircraft into the United States’ leading defense electronics firm which dominated in the markets for air defense, radar systems, tactical missiles and satellites. He began his PhD in 1941 at Caltech at the invitation of Theodore von Kármán. While at GALCIT he helped design a new supersonic wind tunnel, the first of its kind in the country. Later, he produced the calculations that led to the development of delta wing theory, which predicts the aerodynamics of supersonic aircraft and continues to be applied in the production of modern aircraft.
