Those magnitudes are barely worth mentioning unless you were on a route and felt it.
We've been at the base of machete (Destiny Wall) when there was a 4.0 and I didn't even feel the shaking. Kat said she felt it because she was sitting down. Another day we were out at The Knee and Onomatopoeia and we felt a jolt from another small quake but nothing after. Cochran and Caleb were climbing Blowing Chunks and I was working.
No self-respecting seismologist would even mention a 4.0 much less think it was news-worthy.
