«We've been hamstrung without in situ measurements of
frictional stress, and we now have that from the temperature data,» she said.
The JFAST results show that
the frictional stress on the shallow portion of the fault was very low during the earthquake, which means that either the stress was low to begin with or all of the stress was released during the earthquake.
