Steam-driven blast at Hawaii volcano could shower island with huge rocks

These is a risk of powerful explosions at Kilauea volcano, that may shower the area with giant boulders, toxic fumes and ash, the USGS warned. The ongoing eruption has already forced hundreds of residents out of their homes.
With lava continuing to pour from the Kilauea crater, there is a growing chance that its level will go below that of groundwater, which in turn, will trigger a chain of steam-driven explosions when the two substances mix, the US Geological Survey warned. The explosions could strike Hawaii's Big Island virtually any minute, as long as the Kilauea volcano, which has been erupting since last Thursday, is active, the geologists said.
