为了测试热通量勘探的潜力，在活火山地区沿垂直剖面浅层温度数据，我们进行了两次热剖面调查，一个不远处的Yasur锥Tanna岛，另一个内的Ambrym（新赫布里底群岛弧，西南太平洋）的破火山口。考虑到传导和对流传热，确定了内部火山成因的基本稳定热通量。在这两个位置，在小距离上，热通量存在显著差异。这些差异对应于浅层热源。利用垂直剖面网络可以：（a）绘制热通量图;（B）确定浅层火山热源的位置;（c）观察静止但活跃的火山的热量释放的详细结构。
To test the potential of heat flux prospecting in active volcanic areas using shallow temperature data taken along vertical profiles, we carried out two thermal profile surveys, one not far from Yasur cone on Tanna Island, and another inside the caldera of Ambrym (New Hebrides arc, southwestern Pacific). The basic steady heat flux of internal volcanic origin was determined, taking into account both conductive and convective heat transfers. At both locations there exists, over small distances, significant differences in the heat flux. These differences correspond to shallow sources of heat. The use of a network of vertical profiles allowed: (a) heat flux mapping; (b) location of shallow volcanic heat sources; and (c) observation of the detailed structure of the heat release at quiescent but active volcanoes.
