{"Title":"Volcanic explosivity index scale","Description":"Discover the power of volcanic eruptions with this interactive spin wheel! The Volcanic Explosivity Index (VEI) classifies eruptions from non-explosive to mega-colossal based on the volume of erupted materials and eruption column height. Each slice on the wheel represents a different VEI level, ranging from VEI 0 (Non-explosive) to VEI 8 (Mega-Colossal). For example, the 1980 eruption of Mount St. Helens was a VEI 5 (Paroxysmal), while the 1815 eruption of Mount Tambora was a VEI 7 (Ultra-Plinian).","FontSize":9.5,"LabelsList":["VEI 0 (Non-explosive)","VEI 1 (Gentle)","VEI 2 (Explosive)","VEI 3 (Severe)","VEI 4 (Cataclysmic)","VEI 5 (Paroxysmal)","VEI 6 (Collosal)","VEI 7 (Ultra-Plinian)","VEI 8 (Mega-Collosal"],"Style":{"_id":"68f6206fc5981e94b3c15ae6","Type":0,"Colors":["#4caf50","#ffffff","#8bc34a","#cddc39","#ffeb3b","#ffc107","#000000","#ff5722","#710d06","#741c00"],"Data":[[0,1],[2,1],[3,1],[4,1],[5,6],[7,6],[8,6],[9,6],[9,1]],"Space":null},"ColorLock":null,"LabelRepeat":1,"ThumbnailUrl":"https://spinthewheel.app/assets/images/preview/volcanic-explosivity-index-scale.png","Confirmed":true,"TextDisplayType":null,"Flagged":false,"DateModified":"2025-10-24T07:00:55.272Z","CategoryId":13,"Weights":[],"WheelKey":"volcanic-explosivity-index-scale"}
