I was told by my contractor:
The soil in Hawaii has a large glass component, glass is an insulator.
consequently when there is a cloud to ground strike the lightning ball "hops" around as it tries to find a ground. This also explains why code out here requires more grounding rods, be aware of that as you add cable, telephone and antennas. Ground, ground, ground if you do not want that lightning ball hoping from appliance to appliance - heads up you off grid folks who do not have a helco approved grounding system to piggy back on ... make sure your genset, solar etc is well grounded
