If there is any country that is prepared for a major earthquake, the United States of America is one of them. I think the U.S.A. has some of the best emergency response teams in the world. And America faces some of the most natural disasters every year. I have no doubt that an earthquake is something American can deal with in a professional manner.
The United States had a very hard time dealing with Katrina not so long ago. The United States could be better prepared for natural disasters in general. There are some good things they have and could do, but there is a lot of room for improvement and preparedness for natural disasters.
The United States is barely prepared for the hurricanes that happen every year let alone the damage that an earthquake could do on a large scale. It could really set the United States up for a huge problem that we may not be able to get out of. The Red Cross would not be able to help everyone and there could very quickly be a food shortage.
The United States is not properly prepared for a major earthquake, even in California. It has been such a long time since a large earthquake caused damage to the United States, people forget and they get complacent about preparing for an earthquake. California needs to certainly be aware of this danger.
I do not feel that the United States is prepared for a major earthquake. Of course some states are more prepared for earthquakes than others. States like California would be more prepared because earthquakes are common. Other parts of the US lay on a fault line but are not prepared because there have been very few earthquakes.
