We can. Scientists have made investigation on earthquakes. They have made maps showing the "Earthquake belts". In areas along these belts, earthquakes are likely to occur. In these areas we can build special houses to resist earthquake shocks and protect ourselves. In the future, scientists will...

It is not only earthquakes that you may need to keep in mind as risks of natural disasters in Japan. As sea temperature levels rise due to global warming in recent years, typhoons are beginning to originate closer to Japan, and are becoming more powerful. Tropical storms, which arise from ...
Ear diagram courtesy NASA Your brain determines the horizontal position of a sound by comparing the information coming from your two ears. If the sound is to your left, it will arrive at your left ear a little bit sooner than it arrives at your right ear. It will also be a little bit...
During the Earth's history,tectonic plate movementshave created oceans and shifted continents, shaping the world we see today. Earthquakes occur all over the world, but they're more frequent and intense near fault lines. In the US, 16 states are at thehighest risk of natural ...
In the diagram below there is a sign hanging from a pole. The pole is fixed to the wall at one end, and there is a cable running from the end of the pole up to the wall for added support. What is the minimum tension the cable must support to keep the sign ...
Since the local stress conditions control the fault motion during an earthquake, a motion reversal along the same fault segment would require a substantial temporal stress change. Should the two reversed earthquakes occur along neighbouring structures, rather than a single one, the proposed models expl...
