  2. 2. Seismic Zone Information www.aeiconsultants.comSince its founding in 1992, AEI Consultants has performed thousands of The AEI seismic map identifies seismic zones from zero to assessments on various commercial property types for both These zones are defined as:private and public clients throughout North America. Zone 0: Very low risk. No seismic requirementsProperties in seismically active areas have a higher risk of suffering significant Zone 1: Low Risk of damaging seismic activitydamage in the event of the major earthquake. Knowing the seismic risk of Zone 2A: Low to moderate risk of damaging seismic activityyour property is important to avoid future expenditures. The information Zone 2B: Moderate risk of damaging seismic activityprovided on the map is based on the 1997 Uniform Building Code, published Zone 3: Moderate to high risk of damaging seismic activityby the International Conference of Building Officials. The United Stated is Zone 4: Highest risk of damaging seismic activitydivided into four seismic zones depending on hazard risk. Please review themap on the reverse to determine what seismic zone your property is in. The Probable Maximum Loss (PML) is defined by the American Society for Testing and Materials (ASTM) in Standard Practice E2026-99. The report summarizes the risk of structural failure due to the vibratory motion from the maximum probable earthquake. The PML is expressed as a damage ratio (percentage) that determines the approximate repair cost divided by the replacement cost of the building due to a large seismic event, commonly referred to as the "475-year event." This calculation is used by lenders to determine the conformance to lender standards required to fund a loan. The PML takes into account various factors including construction type, date, site condition and location of the building.There are two methodologies employed by AEI to find the PML percentage.1. Scenario Expected Loss (SEL)- The average expected value loss to the building resulting from a seismic event.2. Scenario Upper Loss (SUL)- The scenario loss that has a 10 percent probability of exceedance due to the specified ground motion of the scenario consideration.Each method determines the maximum probable earthquake loss, but the methods and calculations involved differ.The specific methodologies are governed by the lender, but all include the following: - Cursory review of available geologic and soils reports and drawings. - Site visit and general assessment of the property, building(s), related facilities and general site characteristics. - Preliminary assessment of earthquake ground shaking, liquefaction and fault surface rupture potential based on historical regional hazard data. - Preparation of a report including a list of general seismic deficiencies and preliminary estimate of facility earthquake damage loss based on empirical loss estimation methodologies.
