directions and pick different categories from the “ground”, “prevention”, and
“magnitude” topics at the top. Once groups are picked, click on “begin quake”. Keep
picking different variations until you design a system with the least damage to the
building when the magnitude is a tremor, a quake, and a superquake. You should try 1520 different variations before you can accurately decide which is best. Write down the
best ones below.
