Earthquake engineering
is the study of the behavior of
building structures
subject to
earthquake
impacts. It is a
subset
of
civil engineering
.
Objectives of the earthquake engineering
[

The main goals of earthquake engineering are:
- Understand what happens between buildings and the ground.
- Understand what strong earthquakes or
tsunamis
might do to building structures.
- Design
, build and maintain structures to last during an earthquake while following
building codes
.

A properly engineered structure does not necessarily have to be extremely strong or expensive.
The most powerful and affordable tools of earthquake engineering are
vibration control
technologies and, in particular,
base isolation
.
To test
seismic performance
of a
building structure
with experiments, it may be put on a
shake-table
that behaves like the
earth shaking
. The earliest shake-table experiments were performed more than a century ago.

Tsunami preparedness and protection

Tsunami
or a
chain
of fast moving
waves
in the
ocean
caused, mostly, by powerful
earthquakes
is a very serious challenge for people's safety and for
tsunami protection
of
buildings
and civil
infrastructure
. Those waves can flood coastal areas, destroy
houses
and even swipe away whole
towns
.
[3]
Though tsunami can not be prevented, there are
warning systems
developed recently
[4]
which warn the
population
before the big waves reach the
land
to let them enough time to rush to safety.
