Eruption of Hawaii's Kilauea Volcano Triggers Evacuations
Helicopter overflight of Kilauea Volcano's lower East Rift Zone on May 22, 2018, shows the lava channel emerging from Fissure 22 (not visible but to the center, far right of the image). The lava is flowing downhill, from right to left in the photo. A moderate-level eruption of lava continues along the northeast end of the active fissure system. As a result, volcanic gas emissions have tripled from Fissure 20 resulting in elevated to higher levels of Sulfur dioxide throughout the area downwind of the vents. Photo by USGS/UPI
The NASA/German Research Centre for Geosciences GRACE Follow-On spacecraft launch onboard a SpaceX Falcon 9 rocket, on May 22, 2018, from Space Launch Complex 4E at Vandenberg Air Force Base in California. The mission will measure changes in how mass is redistributed within and among Earth's atmosphere, oceans, land and ice sheets, as well as within Earth itself. GRACE-FO is sharing its ride to orbit with five Iridium NEXT communications satellites as part of a commercial rideshare agreement. NASA Photo by Bill Ingalls/UPI

Eruption of Hawaii's Kilauea Volcano Triggers Evacuations
View taken on May 20, 2018, of the lava flow reaching the ocean. Hot lava entering the sea creates a dense white plume called "laze" (short for "lava haze"). Laze forms as hot lava boils seawater to dryness. The process leads to a series of chemical reactions that result in the formation of a billowing white cloud composed of a mixture of condensed seawater steam, hydrochloric acid gas, and tiny shards of volcanic glass. This mixture has the stinging and corrosive properties of dilute battery acid. Because laze can be blown downwind, its corrosive effects can extend far beyond the actual ocean entry area.
