This funding includes $1.5 million for operations at high-threat volcanoes, over $4 million for next generation detection systems, and $4.8 million for interim office and laboratory space, equipment, and other needs due to the destruction of the Hawaiian Volcano Observatory and continuing volcanic activity at Kilauea.
Their topics include voluminous and compositionally diverse middle Miocene Strawberry volcanics of northeastern Oregon: magmatism cogenetic with flood basalts of the Columbia River Basalt Group, quaternary glacio-volcanism in the Canadian Cascades volcanic arc: paleoenvironmental implications, new perspectives on the 19th-century golden pumice deposit of Kilauea Volcano, and the communication strategy of the US Geological Survey Hawaiian Volcano Observatory during the lava-flow crisis of 2014-15 at Kilauea Volcano.
The Hawaiian Volcano Observatory says Tropical Storm Lane had little effect on the volcano beyond some minor rock falls at the summit.
The Hawaiian Volcano Observatory says sulfur dioxide emissions also have tripled.
At the volcano's summit, another large explosive eruption occurred around midnight, sending up a nearly two-mile-high ash plume (10,000 feet), according to the Hawaiian Volcano Observatory. There was another explosion around 4 p.m.
There were occasional bursts of ash coming from the crater, causing ash to fall downwind to several communities, though there were only trace amounts, said the Hawaiian Volcano Observatory.
"Debris expelled during such explosions could impact the area surrounding HalemaE'umaE'u and the KA'lauea summit," the Hawaiian Volcano Observatory (HVO) told the Star-Advertiser, (http://www.foxnews.com/science/2018/05/10/hawaiis-kilauea-volcano-could-be-ready-to-blow-scientists-say.html) Fox News  reported. 
Eruptions of lava and gas were expected to continue, along with aftershocks from Friday's 6.9 magnitude earthquake, the largest in the area since 1975, according to the Hawaiian Volcano Observatory.
The USGS Hawaiian Volcano Observatory said Sunday afternoon that since the overnight hours, eruptions of lava from cracks in the ground have been continuous.
The USGS's Hawaiian Volcano Observatory issued a notice in mid-April that there were signs of pressure building in underground magma, and a new vent could form on the cone or along what's known as the East Rift Zone.
The scientist in charge of the Hawaiian Volcano Observatory, Christina Neal, said the earthquake didn't appear to affect Kilauea's eruptions, AP reported.
