Deep Columbia M7.4 earthquake

 


This is an 'every day' earthquake for this region. It was quite deep and looks like 20 cm/s on the surface.  Most likely 5 cm/s on rock.  People are generally situated on deep soil basins or valleys.  Any size of earthquake can get them going.  They should have better construction, but who knows?

ps their site is all pga, and I can't find pgv
