Hazard Risk Estimates Practice Test

A city planner must decide where to focus preparedness for landslides. Use the table to reason about overall risk (likelihood + impact). Risk is an estimate, not certainty.

Data (past 25 years):

• Slope District: 11 landslides; 1 school and 300 homes on steep slopes
• Valley District: 3 landslides; 4 schools and 4,500 homes on steep slopes
• Ridge District: 7 landslides; 2 schools and 900 homes on steep slopes

Where should preparedness efforts focus most based on the data?

A wildfire map uses color to show fire frequency (likelihood indicator): dark red = many fires, light yellow = few fires. A separate layer shows critical facilities (hospitals, power stations) that could be affected (impact indicator). Risk combines likelihood and impact; it is not certainty.

Map description:

• Sector North: dark red; 1 hospital
• Sector Central: light orange; 4 hospitals and 2 power stations
• Sector South: dark red; 0 critical facilities

Which preparedness focus is best supported by the map evidence?
