Hazard Risk Estimates Practice Test

A school district compared earthquake risk for two zones using a map of past shaking intensity (likelihood proxy) and a table of building vulnerability (impact proxy). Risk combines likelihood and impact; it does not mean an earthquake will definitely happen.

Map summary (largest shaking reported since 1970):

• Zone 1: mostly intensity VI, with a few areas at VII
• Zone 2: mostly intensity V

Which zone likely has greater potential impact if strong shaking occurs, based on the vulnerability table (not on likelihood)?​

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?​
