It is not clear why bolts of lightning are sometimes seen within erupting volcanoes...

4. ...One theory is that that the spewing magma bubbles or particles of volcanic ash are themselves electrically charged, and by their motion create separately charged areas...
                                                                                             

5.                                                                                              
...Another theory is that lightning may be caused by charge-inducing collisions in volcanic dust

6. Several photographers have captured this phenomenon at the Icelandic volcano
