Earthquakes , even if they were thousands of miles away , did cause strong enough movements in the magnets to negatively affect the beam quality and even disrupt it . Therefore , tiltmeters were installed on Tevatron 's magnets to monitor minute movements and to help identify the cause of problems quickly . The first known earthquake to disrupt the beam was the 2002 Denali earthquake , with another collider shutdown caused by a moderate local quake on June 28 , 2004 . Since then , the minute seismic vibrations emanating from over 20 earthquakes were detected at the Tevatron without a shutdown , like the 2004 Indian Ocean earthquake , the 2005 Nias – Simeulue earthquake , New Zealand 's 2007 Gisborne earthquake , the 2010 Haiti earthquake and the 2010 Chile earthquake
