How can we solve the problem of earthquake

Actually we can't control the destructive forces of nature - earthquke. But we can minimize the destrutive force of earthquake. By the following suggestions and equitments:

1) earthquake-detecting equipment which can help us design and construct buildings, bridges and other structures that can better withstand those forces from earthquke.

e.g. Jr. Network for Earthquake Engineering Simulation (NEES).

NEES is a collaboration designed to improve the seismic design and performance of the U.S. civil and mechanical infrastructure.

2) methods of retrofitting buildings so that they can better withstand damage.

for instance:investigate the use of smart materials systems in retrofitting buildings to withstand earthquake damage.

3)study the use of soil-strengthening techniques .

such as, grouting and deep densification to help prevent earthquake-induced liquefaction and lateral spreading of the ground.

Others :

for example: some fluid seismic dampers will minimize earthquake damage to wood-frame homes.

Earthquake is a problem of nature, we cannot prevent it. We can only minimize the damages done by earthquakes by inventing more precision equipments that can precisely detect the occurrence of any oncoming earthquakes. Also we can build more strong buildings that can stand the impacts by earthquakes.
