Burners Without Borders volunteers building a cornerstone. The forms that they are putting up will be filled with concrete and removed when it has dried. A rebar internal frame should prevent these structures from falling in a quake, meaning people can build a cheap brick or adobe house around the cornerstone and use it for a shelter if another quake hits. In the meantime the fact that the cornerstones have a toilet and shower means sanitation conditions will improve greatly.
