Comment on this resource
In this activity, learners will look at some of the characteristic properties of aftershock sequences, and relate them to variables in two equations: the modified version of Omori's Law, and the Gutenberg-Richter relation for aftershock sequences. The database provided in this link can be searched to extract the magnitude and time-after-mainshock for selected earthquakes. From this information, users can discover the real-world meanings of various properties of aftershock sequences.
