New signs of volcano eruption

“Ballistic blocks” the size of microwave ovens shot from Hawaii’s Kilauea volcano on Wednesday in what may be the start of explosive eruptions that could spew huge ash plumes and hurl smaller rocks for kilometers, the US Geological Survey said. Such eruptions, last seen nearly a century ago, have been a looming threat since Kilauea, one of the world’s most active volcanoes, erupted nearly two weeks ago.
