About this tag
Richard Gross is a NASA scientist at the Jet Propulsion Laboratory (JPL) who studies how earthquakes affect Earth's rotation. In this forum thread, members discuss his calculations showing that the 2011 Japan earthquake shortened the length of a day by 1.6 microseconds and shifted the planet's axis by about 15 centimeters. The discussion compares this to the 2010 Chile earthquake, which reduced the day by 1.2 microseconds. The thread explores the scientific implications of these changes and the methods used to measure them.
