Hi DrivenData team, and thanks again for the earlier clarifications on known-fault masking and the 300 m rule, they were very helpful. One more question on how the distance-weighted Tversky score is aggregated: Is the …

Hi all, I’m competing solo and looking for one teammate with a geoscience background, ideally someone who has mapped Quaternary faults or scarps on lidar in Nevada or the Walker Lane. Where I am: a working end-to-end p…

Hello. Could we please ask three questions about data sources and fault types involved in identifying the new test faults? We’d like to have better insight into how they were identified, so we can choose appropriate inpu…

I’m still curious where you draw the line between a correction to an existing fault and a new fault. Like, if a mapped USGS/INGENIOUS fault appears to continue beyond its existing endpoint, can that previously unmapped …
