These are the parts of SF that are highest risk during an earthquake, meaning that from a physics/geology perspective, *the land under you will react to an earthquake like a liquid*pic.twitter.com/nHcqMfe49f

San Francisco: Remember that the sea wall will crumble during our next *medium strong* earthquake. And the land under FiDi/Soma/Marina/Mission Bay acts as a liquid, meaning it will spill into the Bay absent the sea wall. And the Market Street Muni tunnel will fill with water.https://twitter.com/laura_nelson/status/1146840558272274432 …

This is not an exaggeration. Have you ever seen a pool or a lake after an earthquake?!pic.twitter.com/SbHhgACxEU

Sooo what do we do about that? Bike to work instead of train? Does Prop A help once construction is complete?
-
Yep! We are way behind schedule but the Prop A bonds are being spent on repairing/patching the most weak and vulnerable parts of the wall. It’s only a small fraction of what’s needed though.

Didn’t we pass a 500 million bond to fix the sea wall? Did we do anything more than find California Coastal Commission meetings for the next decade???

This is a bit of hyperbole. There were many high rises on landfill in SF that were fine during the 89 quake. Downtown did not “spill out into the bay” treasure island is pure landfill and it lived through 89.

1) The sea wall has crumbled significantly since/during 1989. 2) 1989’s epicenter was more than 60 miles away. 3) High likelihood we have a quake stronger than 1989 in the next 25 years. https://www.sfseawall.com/2904/documents/3737/download …pic.twitter.com/fVHVLj9ppM

Also most of the Bay Area has not retrofitted their soft story buildings. The vast majority of small cities on the Peninsula/South Bay have not.
