Cinna Lomnitz Aronsfrau (born May 4, 1925 – died July 7, 2016) was an important Chilean-Mexican scientist. He was a geophysicist, which means he studied the Earth's physical processes. He was especially known for his work on how rocks behave and how earthquakes happen.

Early Life and Learning

Cinna Lomnitz was born in Cologne, Germany. His family was Jewish. He finished his engineering studies at the University of Chile in 1948.

Later, he studied at Harvard University and earned a Master's degree. This degree was in soil mechanics, which is about how soil behaves.

In 1955, Lomnitz received his doctorate from Caltech. His main research was about how rocks slowly change shape over time. This idea became known as the "Lomnitz Law." It helps scientists understand how rocks deform under stress.

His Career and Discoveries

Lomnitz became the first director of the Institute of Geophysics at the University of Chile. This was a big step for studying the Earth in Chile.

From 1964 to 1968, he taught at the University of California-Berkeley. Then, in 1968, he moved to Mexico. He joined the National Autonomous University of Mexico's Institute of Geophysics. He worked there for the rest of his life.

In 1971, he started Mexico's first seismic network, called RESMAC. This network helps to detect and study earthquakes. He also became the editor of a science magazine called Geofísica Internacional in 1990.

Lomnitz wrote several books. One of his most famous books was Global Tectonics and Earthquake Risk, published in 1974. This book helped many people understand how Earth's plates move and cause earthquakes.

His Family Life

Cinna Lomnitz married Larissa Adler Lomnitz, who was a social anthropologist. They had four children: Jorge, Claudio Lomnitz, Alberto, and Tania. Cinna Lomnitz passed away in Mexico City in 2016 when he was 91 years old.
