Question

1) how has technology help to decrease the damage due to earthquakes? 2) what is the San Andreas fault?

Answer 1

New building techniques and materials allow buildings and other infrastructure to survive earthquakes intact. Motion detectors placed in structures in earthquake zones provide detailed information about the way buildings respond to ground motions, and this helps to develop earthquake resistant building methods.

The San Andreas Fault is a Transform fault with a right lateral strike-slip motion, where two tectonic plates are sliding past each other:  This means that Baja Clifornia is tending to move North West relative to the rest of North America.  It is a very active fault and prone to large quakes.  

Answer 2

In areas where earthquakes are a large risk, structures being built there have been built with earthquakes in mind, so they are built in a way that allows them to 'sway' slightly with the earthquake, because if they were rigidly built like other buildings elsewhere they wud just crumble.

The San Andreas Fault is the line between the two tectonic plates that meet in california. When these move together, earthquakes occur. this is why california is prone to earthquakes...as it lies on the san andreas fault.

Answer 3

In general we now have more awareness on disasters. We have improved our building design to withstand at least up to Richter scale 8.But we have not yet succeeded in prediction.
