| 摘 要： | 阐述了龙岗火山的地质构造及历史喷发特点，重点分析了龙岗火山区的现今地震活动性及地壳变形特点。结果表明，龙岗火山区现今地震活动性在不断增强，震源深度逐渐变浅；地壳形变有明显变化，火山活动趋于加强，未来潜在喷发的危险性不容忽视。

| Abstract: | This article elaborated the Longgang volcano eruption characteristics of geological structure and history. Focus on the analysis of the Longgang volcano area of current seismic activity and crustal deformation characteristics. The results showed that, the Longgang volcano region nowadays in seismicity increases ceaselessly, focal depth becomes shallower, crustal deformation has obviously changed, volcano activity tends to be strengthened, the potential eruptive risk should not be neglected in the fature. |

| Keywords: | Longgang volcano eruption risk seismicity crustal deformation |
