    • The magnitude range for 95% of these events is between 2.5 and 4.0; however, our data set includes a few events with larger magnitudes, up to 6.8.

    • The mean and standard deviations of the compressional-wave velocities at the intraslab earthquake locations, grouped according to the event depth relative to the reflector, are as follows: 7.3 ± 0.3 km/s for events more than 2 km above the reflector; 7.6 ± 0.3 km/s for events within 2 km; and 7.9 ± 0.1 km/s for events more than 2 km below the reflector. See table S1 for distribution.
