Annual report dates come from the budget period on your award notice. That date is not public, so it is not shown here.

How we got this date

NSF lists this award's end date as 31 July 2029.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 28 November 2029.

Abstract

Earthquakes of similar size vary in the strength of the damaging ground motion that they produce. Understanding why this variation occurs is important for making better predictions of future ground motions during earthquakes. One approach to describing these differences involves a quantity termed "stress drop," which is related to the amount of energy released during earthquakes. However, earthquake stress-drop…
