Some architects have taken the challenge of building earthquake proof structures. Some use a base isolation method and others use cross bracing. There are other ways as well, those are just the most common methods though. These structures can be earthquake emergency facilities or sometimes, people use this architecture in their homes, sparing the contents in earthquakes.

-Epicenter: the place on the surface, right above where the earthquake originated from
-Hypocenter: the exact place that the earthquake originated from

To find an epicenter, you have to know 3 places that felt tremors. Then using a seismographs chart, find the time it took for the waves to hit. Measure this on a special graph and set your compass to that distance. Draw the circles around each point and see where they all intersect. That's your epicenter.

-P-waves: primary, faster and weaker waves that are felt first
-S-waves: secondary but stronger waves that cause the real damage
-Surface waves: waves trapped near the surface, violent
