More destructive lava flows could soon hit Hawaii's Big Island as the Kilauea volcano erupts, posing a greater threat than oozing magma that has so far destroyed dozens of homes and forced thousands to evacuate, scientists said on Friday.
As a lava lake at Kilauea's summit drains inside the volcano, magma is running underground. It could burst to the surface as large, fast-moving and intensely hot lava flows and produce higher levels of toxic gases, Hawaiian Volcano Observatory scientist-in-charge Tina Neal said.
"What will take a turn for the worse in terms of hazard is if hotter, fresher magma makes it to the surface, and that could be what is coming," Neal told a conference call. "Once a new batch of hotter, gassier magma makes it to the surface we might see larger, higher eruption rates."
