Answer: \u00a0Ah ha! \u00a0Trick question…it’s both!<\/p>\n

There are two main types of electrical charging that lead to lightning during a volcanic eruption: \u00a01) “frictional charging” from colliding particles of volcanic ash and 2)\u00a0\u201cice charging” from the freezing and growth of ice and hail. The first happens during all types of explosive\u00a0eruptions, because there are always ash particles colliding with each other, especially close to a volcano\u2019s vent. However, \u201cice charging\u201d only occurs\u00a0when the ash plume reaches high into the freezing-cold parts of the atmosphere. When this happens, the electrification\u00a0becomes much more intense, and more like a regular thunderstorm.<\/p>\n
