# Does ash ever erupt from Kīlauea Volcano??

Kīlauea Volcano is renowned for its relatively benign eruptions of fluid lava flows. Therefore, many people were surprised by the small explosions that occurred in Halemaumau Crater in 2008 and 2018, and even more surprised to learn that volcanic ash was being erupted from a new gas vent. However, ash emissions from Halemaumau Crater are part of the volcano's legacy.

Kīlauea's summit has erupted explosively throughout the history of the volcano, producing ash deposits that date back at least 30,000 years—and probably older.

In 1790, at least 80 people were killed in the Kaū Desert by searing hot gas and ash produced by a devastating explosion. In 1924, a series of steam explosions in Halemaumau Crater blasted columns of volcanic ash and dust as high as two miles (3 km) into the air. These plumes were blown downwind beyond the community of Pahala, 32 km (20 miles) away, where ash fallout turned day into night. Muddy ash also fell in lower Puna, making railroad tracks so slippery that trains couldn't travel in Makuu. One person was killed near Halemaumau when he ventured too close to the vent and was hit by falling rocks.

On May 17 in 2018, an explosive eruption at the summit of Kilauea produced a volcanic cloud that reached as high as 30,000 feet above sea level.

### Dramatic Developments at Kilauea Volcano

Kilauea Volcano in Hawaii has experienced its first explosive eruption in more than 80 years and is now spewing noxious gas at 10 times the normal rate. John Eichelberger, head of the USGS Volcano Hazards Program, fills us in on the situation.
