TER 3. HAZARD IDENTIFICATION AND RISK ASSESSMENT
-y of Nashua is susceptible to a variety of natural hazards, which are outlined in Table 2. For each hazard type, the hazard location
y, extent, and impact are also noted. Extent refers to how bad the hazard can be; it is not the same as location. Examples of extent
» potential wind speed, depth of flooding, and existing scientific scales (ex. Fujita Tornado Damage Scale). Impact refers to damages
juences resulting from the hazard.
