"The Biggest One" - Hiroo Kanamori Interviewed on the 50th Anniversary of Chile's 1960 Magnitude 9.5 Earthquake

Hiroo Kanamori, Caltech Professor Emeritus is interviewed by Nature on the 50th anniversary of Chile's 1960 magnitude 9.5 earthquake - Nature magazine talks with the experts. Nature magazine's Roff Smith interviews Caltech Professor Emeritus Hiroo Kanamori as he looks back at the largest earthquake ever recorded.

About Hiroo Kanamori: In 1977 Dr. Hiroo Kanamori developed the Moment Magnitude scale, which replaced the Richter scale for measuring earthquakes M5.0 and larger. Using the improved method, scientists were able to obtain more precise measurements of the energy of large earthquakes that occurred in the past, such as the 1960 Chilean earthquake and the 1964 Alaskan earthquake, as well as a better means of studying and analyzing seismic events when they occur.
