Order No 3274 of the President of the Council of Ministers of 20 March 2003, in Official Gazette No 105 of 8 May 2003, lays down the general principles on the basis of which the Regions, to which the State has delegated the adoption of the seismic classification of the territory (Legislative Decree No 112 of 1998 and Presidential Decree No 380 of 2001 — ‘Consolidated Text of the Rules for Buildings’), have drawn up the list of municipalities with the corresponding allocation to one of the four areas, with degressive danger, in which the national territory has been reclassified. Zone 1 — It is the most dangerous area, where strong earthquakes can occur Zone 2 — In the municipalities included in this area there may be quite strong earthquakes Zone 3 — Municipalities included in this area may be subject to modest shaking Zone 4 — It is the least dangerous zone The seismic classification (seismic zone belonging to the municipality) remains useful only for the management of planning and for the control of the territory by the competent authorities (Region, Civil Engineer, etc.).2003年3月20日部长会议主席第3274号命令刊载于2003年5月8日第105号官方公报，该命令确立了通用准则：意大利国家已将国土地震区划职权委托给各大区（依据1998年第112号立法法令及2001年第380号总统令——《建筑规范统一文本（Consolidated Text of the Rules for Buildings）》），各大区据此编制市镇名录，并将全国领土重新划分为4个危险等级递减的地震分区，为对应市镇分配所属分区。 1区：为最高危险区域，可能发生强震； 2区：该区涵盖的市镇可能发生较强地震； 3区：该区涵盖的市镇可能遭受中等偏弱的地震晃动； 4区：为最低危险区域。 该市镇地震分区分类仅在规划管理及主管部门（大区、土木工程师管理机构等）对国土的管控工作中具备实用价值。
