The Power of Volcanic Lava Fountains: Exploring the Phenomenon

Volcanic activity from hotspots can be both calm and explosive. While lava typically flows down the mountainside in a slow, controlled manner, there are instances where lava is ejected in dramatic fountains that reach staggering heights. Places like Mount Etna, Hawaii, and Iceland have witnessed these awe-inspiring displays of nature’s power.

The recent eruptions at Kilauea Volcano have provided researchers with unprecedented insight into lava fountain activity. In a recent publication in Science, experts from the U.S. Geological Survey elucidate the characteristics of lava fountains and compare them to existing scientific theories.

Unveiling Kilauea Volcano’s Fountain Activity

Despite being the newest and most active volcano in Hawaii, Kilauea has only experienced three significant eruptions since 1823. These events sparked intensive research efforts and offered valuable information about the volcano’s internal structure. Previous studies had identified lava reservoirs close to the surface, and Kilauea was equipped with 35 data collection stations, including seismic, geodetic, and thermal cameras.

Explore the 2018 Major Eruption In this eruption, one of the underground lava reservoirs was partially drained, leading to significant changes in the volcano’s behavior. Subsequent years saw accelerated backfilling of the reservoir, causing expansion in the nearby caldera at an alarming rate. By 2023, the backfilling rate had doubled, posing new challenges for scientists studying Kilauea’s volcanic activity.
