Excellent stuff on base isolation. Bets one on youtube. Please translate in English.

Works for the P-wave. I wonder if they're doing anything about the S-wave (up/down movement)?

This is a great video, but I barely understand, could you probably add some subtitle in English, please?

What material is used in the creation of those isolators

why does it matter is not like you can make it yourself.

Laminated isolation devices are made of laminated rubber and steel plates with a lead core. The rubber provides damping characteristics same as the lead since it is very ductile and can deform laterally. The steel supports the vertical load transmitted to the ground.

@@786otto Yes you are right but only if we buy it from ‘them’. Maybe it is time we study other designs (not rubber) and try to invent a cheaper but equally effective method? I was thinking a solid ball between two solid concave disks mounted on top of each other and attached to each foundation column which can isolate a two-storey house from ground horizontal movement and center itself back when earthquake stops. Not easy but sounds possible, doable and cheaper. 😉
