A few nights ago I had the same dream three times during the night. In these dreams there was a sudden change in the volcanic activity in the Hawaiian Islands. The Big Island began having long duration seismic events and both Mauna Loa and Mauna Kea began to emit stem and ash. Volcanoes on the other island began to show signs of awakening. There was a sudden increase in magma output coming from Kileua.
All of the islands began to shake with long duration earthquake. Then Mauna Loa erupted. Honolulu was struck by a large earthquake that caused a portion of the city to collapse into the Pacific Ocean. Thousands Drowned.
An order was given to evacuate the Islands. It had to be done entirely by ships from Pearl Harbor because the skies had become so filled by ash and debris aircraft could not travel them.
Then an underwater volcano of tremendous force erupted off shore of The Big Island, causing land submergence and the awakening of new volcanic vents.
When the volcanoes settled down the Hawaiian (islands) were very different. Large land areas had collapsed into the ocean and what was left was covered with gray ash.
