Every year, students that were on the previous year's Seismo Lab Seminar Committee organize a day-long retreat to enable students and faculty of the Seismo Lab to interact with each other outside the academic environment.  This Retreat Committee receives oversight and logistical assistance from Viola Carter (Seismo Lab Office).  The idea of the retreat is to create teams made up of people who do not interact regularly, and devise fun games/sports/challenges that encourage team-building.  The first retreat was held in the Spring of 2005, and retreats have been held annually ever since with generous funding from the Seismo Lab Director, Prof. Jeroen Tromp.  Below are links to retreat pages of the current as well as past years.
