Research Abstract

We drilled a 250 meter borehole to measure the temperature profile across the Cheleungpu fault. This is very close to the location where a temperature anomaly was measured in 2000 following the 1999 Chi-chi Taiwan earthquake. For measurements in 2008 and 2010, we no longer see a temperature anomaly. This suggests that the signal measured in 2000 was a real result of the fault friction during the earthquake.
