step 1 |
define a hazard map: the hazard map shows an estimate of the probability of exceeding a certain amount of ground shaking, or ground motion, in a certain period of time. |
|
|
aim of hazard maps |
- provide info to engineers to design infrastructure that can withstand the shaking of earthquakes - create and update building codes - for local governments to help establish construction requirements necessary to preserve public safety |
|
|
step 2 |
Constructed with historical data and earthquake hazard modeling- data on magnitude, intensities and location of earthquakes that has been collected and recorded over the years. Data will be updated upon every new event |
|
|
step 3 |
complement with modeling based on the geology, seismic gap info, and tectonic plate movement |
|
|
step 4 |
present data in a colour coded hazard risk map
dark red = high risk zones light green to white = low risk |
|
|
an extra note |
[if DRQ gives picture of the degree of risk in different regions → need to specify which region are highest, lowest risk] |
