Is it better to have a building on soft sand or hard rock at the epicenter of an earthquake?

Now, see, if you built a building at the epicenter of an earthquake, no matter what what ground is there, the building will inevitably collapse. Near an earthquake's epicenter, though, is a different story. The best ground would definitely be solid, packed soil. The best foundation for a building would be isolated, unless you had a smaller building like a house, which would be better off with an anchored foundation. The best type of building would have steel frame crossties-only on a skyscraper or tall, large office building like in New York, though.

What happens if you are close to an active earthquake?
depends.. probably an aftershock or something t\depending how hard hte force was and how close to the epicenter you are
During an earthquake where is the greatest motion felt on the surface?
Right at top of the epicenter, the greatest shaking felt. It also depend on the types of soil. If the soil is soft then the intensity is amplified and where the soil is hard the intensity is damped.
How is an earthquake like a stuck door?
It can crush your home, and it can cause exits to be hard to reach
What should be done when earthquake arises?
hide under something like a table (because it is hard)
Which Japanese city was hit by and earthquake in 1995?
9.0. It was originally thought to be 8.9, but after official measurements came in, it was found to be 9.0. This is 5th largest earthquake worldwide since the beginning of the 20th century.

Why are earthquake proof building hard to make?
They cost a lot of money to build.
When an earthquake where is the greatest motion felt on the surface?

How hard did the earthquake hit Japan?
8.9... Pretty hard...
How do earthquake waves change as they spread out from the epicenter?
theres two kinds of waves that are produced...P-waves and S-waves. its kinda hard to explain the difference between them, but if you google them you can find out more.
Where do people first feel the ground shaking during an earthquake?
The strongest shaking is towards the center of the actual earthquake which it is called the focus. The epicenter of an earthquake is the point on the Earth's surface above the focus or hypocenter which is the point within the Earth where the rupture occurs. As such the epicenter is the closest point to this and the seismic waves have had to travel through the smallest amount of material and so have undergone the least amount of attenuation (in this case attenuation is a reduction in amplitude of the seismic waves due to energy being by moving through the Earth). However as with a lot of things in Earth sciences there can be exceptions to this! This is because the amplitude of seismic waves is affected by the density (related to the level of compaction in the case of soils) of the material through which it is traveling). So a seismic wave traveling through a hard rock such as granite will have a much lower amplitude than one traveling through a softer, less dense, poorly compacted material such as a soil and so due to the higher amplitude there will be a higher level of perceived and measurable ground shaking, even an equal distances from the epicenter.
What is the type of earthquake that does damage to roads and buildings?
Depends on how hard the earthquake's damage done on the Richter Scale

you should go under something hard
