Im moving out of Cali in 2 weeks. Hopfully it can wait that long before having a huge quake!

Put on your hard hat and jump in your helicopter, quick!

@Armistice023 Actually, bedrock muffles the movement. Sand will amplify it. Being on a rock or boulder would be the safest place in an EQ, you will still feel it, but it wouldn't knock you over. Being on sand or even worse, landfill, it'll shake you harder and anything built on it will fall to pieces.

@Chammy92243 Because the fault is "unzipping" from north to south. If the EQ starts at the south of the fault, the shockwaves will go west. That's the the USGS guy told me when I asked the same question...

@Chammy92243 Underlying geology is my guess. Rocks transmit the movement better that sand, so it would make sense that the granite makeup of the Sierras would transmit that movement better than the softer soils of the bay. Same would be saying water conducts electricity better than wood. Again, that's just my guess

Why are the waves heading South South East instead of upwards and West?

[antigen4]

because it is. all the displacements are exaggerated or multiplied by 1000 - otherwise you wouldn't see ANYTHING happening. the video tries to show you the geographic distortions that would happen under those conditions.

does anyone know which simulating programme was used for making this video?

darn! i live in Newark CA and the violent is running right where I live!
