*the rest of my points + brainliest! * what can be done to reduce the risk of earthquake damage in tectonically active regions?

You need to make the buildings more flexible like use wood or steel instead of brick or concrete cause they are not flexible. Build triangle structures because triangles are the strongest shapes. You can add a mass damper on top of the building and an active tendon system on the bottom of the building because it will shift the weight around making the building steady. Also install base isolators underneath the sand. Base isolators will absorb the seismic waves. Base isolators are made if layers of steel and rubber wrapped around a lead core. It will prevent the waves from traveling through the building. You can also put flexible pipes which will prevent the pipes from breaking. If it breaks, waterlines and gas lines will leak

Making thing safer than they are because people don't realize that they make more damage than thinking of doing.. hope it helps you

So  if  the sum of the enthalpies of the reactants is greater than the products, the  reaction  will be  exothermic.  if  the products side has a larger enthalpy, the  reaction  is  endothermic. you may wonder why  endothermic reactions, which soak up energy or enthalpy from the environment, even happen
