• vhzones_id ( type: esriFieldTypeInteger, alias: vhzones_id )
• hzone ( type: esriFieldTypeString, alias: hzone, length: 50 , Coded Values: [1: Summits and rift zones of Kilauea and Mauna Loa, where vents have been repeatedly active in historic time. Boundaries are defined by eruptive fissures, cinder cones, pit craters, and graben and caldera faults. Zone 1 is where lava flows originate] , [2: Areas adjacent to and downslope from Zone 1. Fifteen to twenty-five percent of Zone 2 has been covered by lava since 1800, and 25-75 has been covered within the last 750 years. The relative hazard within Zone 2 decreases gradually as one moves away from Zone 1] , [3: Areas gradationally less hazardous than Zone 2 because of greater distance from recently active vents and/or because the topography makes it less likely that flows will cover these areas. One to five percent of Zone 3 has been covered since 1800, and 15-75 oercent has been covered within the last 750 years] , ...6 more... )
