Peak rate and maximum magnitude

Let's use the Tohoku dataset we saved previously.

>> load tohoku_events_1day.mat

To identify the peak-rate in an earthquake sequence such as this preshock-mainshock-aftershock sequence or an earthquake swarm, we can use:

>> eventsObject.plotprmm()

images/events.plotprmm.png

In the command window this returns:

MM=9.1 occurs at 50.0% of time series
PR=32 occurs at 53.5% of time series

These are labelled on the plot above.
