A volcano is remembered by the shape of its mountain, but most of the work happens under the ground. The line running across the middle of the cross-section is the ground surface, and everything below it is underground. Five layers of equal thickness are stacked there, and the roof of the magma chamber lies about two and a half layers down. The layers are a depth scale you can count.
Find the ground surface line, then count how many layers lie between it and the magma chamber.

Observation Mission
檢查火山口出口點選火山口標記，設定熔岩流出的起點。
朝向易流動的條件調整在低黏稠度與低氣體含量下，觀察熔岩流是否勝過爆發。
看著發光的岩流沿坡而下確認熔岩流延伸的狀態，以及外緣暗沉、中心發光的岩流沿坡擴散的樣貌。
Observation Point
觀測標記火山口噴發柱的出口。氣體愈多，含灰噴發柱就升得愈高。
Why This Branch
仍在解讀累積中的變化Pressure 28% is rising, but conduit formation and groundwater contact are not decisive. Combine the small earthquakes, gas, and uplift to see the next branch.
