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 May 2027.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 28 September 2027.

Abstract

Faults that host earthquakes are naturally rough which prevents movement on a fault. Earthquakes begin when stress overcomes the strength of rough patches. This project will advance our understanding of the physics of earthquakes by exploring two mechanisms that may regulate the friction of faults during earthquakes. This project serves the national interest by promoting progress in the science of earthquake hazards…
