The hazards of Hawaiin Volcanic Activity

The HVO, or the Hawaiian Volcanic Observatory, has a great website on their volcanoes…they kinda have to!   I thought the site about the hazards of lava entering the ocean would interest the students due to the danger effect of it.   This site would be great as a webquest and possibly to have groups complete projects on different aspects of volcanoes and the kind of lava flows that occur.
