APPLICATION Now that you have identified
potential hazards and
understand the different types of
hazards, what are the possible
measures to do in order to
mitigate the risk of damage and
loss of life?

41. 41
APPLICATION
Earthquakes can cause significant
damage and loss of life. Mitigating
the risks associated with an
earthquake event requires a
combination of preparedness,
prevention, and response
measures. Some potential
measures to mitigate the risk of
damage and loss of life in an
earthquake event include:

42. 42
APPLICATION 1. Building codes: Ensuring that
buildings are constructed to
withstand seismic activity is one
of the most effective ways to
mitigate earthquake risk.
Building codes should be
updated to reflect the latest
seismic design standards.

43. 43
APPLICATION 2. Retrofitting: Retrofitting
existing buildings to make them
more earthquake-resistant can
be costly but can significantly
reduce the risk of damage and
loss of life.

44. 44
APPLICATION 3. Early warning systems:
Earthquake early warning
systems can provide critical
seconds or even minutes of
warning before shaking begins.
These systems can alert people
to take protective actions such
as drop, cover, and hold on.

45. 45
APPLICATION 4. Public education: Educating
the public about earthquake
risks, preparedness, and
response measures can help
people to be better prepared for
earthquakes. Public education
campaigns can encourage
people to take protective actions
and to be aware of the risks
associated with earthquakes.

46. 46
APPLICATION 5. Emergency planning:
Developing emergency plans
that outline specific actions to be
taken before, during, and after
an earthquake can help to
mitigate the risks associated
with earthquakes. Emergency
plans should include evacuation
routes, safe areas, and
emergency supplies.

47. 47
APPLICATION Infrastructure maintenance:
Maintaining infrastructure such
as bridges, highways, and water
systems is essential to reducing
the risk of damage and loss of
life in an earthquake event.

48. 48
APPLICATION Land use planning: Land use
planning can help to ensure that
critical infrastructure such as
hospitals and emergency
services are located in safe
areas, and that buildings are not
constructed in high-risk areas.

49. 49
APPLICATION Overall, it is important to
remember that mitigating the
risk of damage and loss of life in
an earthquake event requires a
comprehensive approach that
involves a combination of
preparedness, prevention, and
response measures.
