Recent Examples on the Web

Kilauea is a shield volcano with lava that is relatively fluid, so when trapped gas expands and bursts, the resulting eruptions are typically not as deadly. Denise Chow /, NBC News, "Guatemala's deadly volcano eruption: What is the 'Ring of Fire'?," 5 June 2018 What is happening at Kilauea looks a lot like the wreckage left by Newberry Volcano, a shield volcano near Bend, Oregon, that last erupted in the year 690. Author: Scott Wilson, Sarah Kaplan, Anchorage Daily News, "As Kilauea erupts, volcanologists swarm: ‘I expect great science from this event’," 24 May 2018 The two volcanoes are also different shapes: Kilauea is a gently sloping shield volcano, unlike Mount St. Helens, which is a steep-sided stratovolcano, also known as a composite volcano. Doyle Rice, USA TODAY, "Could Hawaii volcano explosion rival Mount St. Helens? Probably not.," 17 May 2018 Whereas Kilauea, a shield volcano, is characterized by large globs of slow-moving lava inching out of fissures, Fuego, a stratovolcano, is prone to spewing fast-moving flows of ash, lava, and mud. Sarah Gibbens, National Geographic, "Why Guatemala's Volcano Is Deadlier Than Hawaii's," 4 June 2018 Kilauea, the volcano in Hawaii that is currently erupting, is a shield volcano. Anna Rothschild, Washington Post, "Here’s why some volcanoes are more explosive than others," 10 May 2018 This allows for different types of eruptions, with shield volcanoes being much less violent. Doyle Rice, USA TODAY, "Could Hawaii volcano explosion rival Mount St. Helens? Probably not.," 17 May 2018 Kilauea is a shield volcano, built of lava spreading out in all directions from a central vent. Robert Krier,, "Kilauea eruption not expected to affect regions beyond Hawaii," 17 May 2018 Like many other Hawaiian volcanoes, Kilauea is a shield volcano that emits fluid basalt lava and is defined by its broad dome shape, rather than a steep peak, like Washington’s Mount St. Helens. Lyndsey Matthews, Popular Mechanics, "The Wild 35-Year History of Hawaii's Constantly Erupting Volcano," 16 May 2018
