No building is seismic safe. No building is earthquake proof. However, there are steps that can be taken to make buildings more earthquake resistant. Concrete buildings made without rebar will collapse in an earthquake. Concrete buildings and concrete block buildings in Guatemala that hold up in earthquakes are those that use a lot of rebar. It is also important to use metal straps to tie the roof to the walls. The straps are inexpensive, but they maintain the integrity of the building. The roof should have cross pieces.
Scientists use devices called Seismographs to determine the epicenter of an earthquake. If 3 or more seismographs detect an earthquake, seismic wave activity can be measured and quantified and then cross-referenced with other data (the primary and secondary seismic waves) to determine the earthquake's location.
Earthquake
Earthquake prone countries prepare for earthquakes by implementing building codes that require structures to be earthquake-resistant, conducting regular drills and exercises to educate the public on how to respond during an earthquake, monitoring seismic activity, and establishing emergency response plans. Additionally, these countries invest in early warning systems and public awareness campaigns to help reduce the impact of earthquakes.

I would like to modify my roof. What are the best roofing materials I should use?
no way no way
something could fall on you, like your roof
You should contact a roofing specialist to decide whether you need a new roof or not. But in the past my shingles roof has worked very successfully to weather conditions.
Patch your roof. If you can afford it put a new roof on the house. This may not be affordable so you can try to patch it. You should use the same roofing material that is on your roof.
Just use those huge staples.
You can use 1) natural thatch roof materials such as water reeds and 2) synthetic thatch roof materials. I recommend the latter if you are planning to put up a long lasting, durable thatch roof.
Use the square footage of your house, and the size of your roof should be about the same. Be carefull not to include the yard in the footage or anything that is not covered by the roof, then divide the number by the number of stories your house is.
you should run when an earthquake is orgared
All houses only need one to two roof gutters depending on how big the home is. My house is pretty big, and we have two roof gutters that we use when it rains.
I have a roof on top of my house
No. You could get trapped and the elevator could fail and crash to the bottom.
