When the ground starts to shake, if the buildings aren't earthquake-resistant, then it's likely the building will collapse on you (that is if you are in a building) If you aren't then the ground can sometimes open up or there's a possibility other things can fall on you. If you're downhill then a rolling car can crush you. To prevent this get into a safe place like an earth-quake resistant building or just move away from a country with earthquakes. Hope this helps :)
It depends on where it strikes. Today's quake in Virginia is in a rather sensitive area, as the U.S. east coast is much less prepared for earthquakes than the west coast and building codes are not as strong. A similar earthquake in California would likely cause a lot less damage. Overall, it is a moderate earthquake.
It can affect the strength, durability, or the sturdiness of the building. If the ground beneath it is sand, It is more than likely to fall during an earthquake or something. Sand is a horrible foundation for a building. Loose soil can also affect the building in the same way, making it slide or sink into the ground.
no one really knows
Any that are built in an earthquake area if you don't want them to fall. And any that would not stand on their own in an earthquake.
It will collapse .

A building that can resist earthquakes can fall down if you put more pressure on them then they were designed to withstand. For example if there was to be a major subsidence directly under half of the building it is likely that it will fall over.
The biggest problem that structural engineers face when designing something to be "earthquake-proof" is the up and down motion created by the S waves. Seismic S waves look and behave very much like a large sheet of poster board when you wave the top of it with your hands, a massive amount of up and down motion is creating, literally lifting the building straight into the air and then dropping it back to earth. Vertical elasticity can be achieved in several ways. First of all, engineers will often make sure that buildings in earthquake zones are built with more metal than concrete, even using wood frames whenever possible. Metal and wood are flexible and ductile, which is the quality one favors in an earthquake. Anything rigid, no matter how strong, will likely shatter if shaken by the immense forces of an earthquake. Another important consideration is the terrain. The ground around a building is often softened up by the vibrations caused by both S and P waves, so engineers need to make sure the building has a solid base to stand on. It is not uncommon for some engineers to run huge beams all the way down to the bedrock, so that the structure has some backup stilts to stand on if the dirt and sand it is built atop begins to liquefy. The important thing to remember is that buildings can be fixed or replaced, but human lives cannot. Engineers aren't' worried so much about making a building usable after a quake, what matters is making sure that nothing falls on anyone.
The energy in the Richter scale will not of itself kill anyone. Indeed if you are outside in an open area you are likely to be safe (baring cracks in the ground and liquefaction. It is things falling on you that will kill you and that depends on the design of the building/structure you are in. A weak earthquake in a poor building can kill you. A strong earthquake in a well built building will probably not kill you.
an earthquake hazard
Structure built to poor standards or no standards are likely to collapse during an earthquake, often killing or injuring people inside. Buildings constructed to modern codes, especially codes that consider earthquakes, are far less likely to collapse.
Along the San Andreas Fault in California is one likely place for an earthquake.
