Lava Fountains: Exploring a Potential Third Type of Volcanic Eruption

Swift Summary:

• Lava fountains are dramatic volcanic phenomena where molten rock is shot into teh air, reaching heights up to thousands of feet.
• Recent lava fountains have been observed at Kīlauea (Hawai’i), Etna (italy), adn Svartsengi (Iceland). These eruptions primarily involve basaltic lava, which is low in silica and highly fluid.
• Famous examples include Izu-Oshima’s 1986 eruption with a mile-tall fountain and the tarawera 1888 eruption in New Zealand reaching an estimated height of ~32,000 feet.
• Products from these eruptions include “Pele’s tears” and “Pele’s hair,” which are droplets or strands of volcanic glass respectively, as well as volcanic bombs that cool enough to retain shape close to the ground.
• volcanologists generally classify eruptions into ‘explosive’ or ‘effusive,’ yet lava fountains don’t fit neatly into either category-it combines characteristics of both while remaining distinct due to fragmentation occurring above ground rather than below it.
• A study led by Giuseppe La Spina suggests magma viscosity and ascent rate play key roles in determining fountain behavior, proposing lava fountains may necessitate classification as a third type of eruption style.

Indian Opinion Analysis:
Lava fountains highlight nature’s complexity challenging rigid scientific classifications like ‘explosive’ or ‘effusive.’ The identification of these events as perhaps forming their own unique eruption style offers critical insights for volcano studies globally. For India-a country prone to seismic activity but with limited active volcanism-studying such phenomena serves vital purposes: improving regional disaster management responses through concrete understanding while aiding global collaboration in advancing predictive tools through such research frameworks.

Understanding magma dynamics from global fountaining events also reinforces India’s need for interdisciplinary approaches across geophysical institutes and policymakers alike-proactively addressing natural hazards worldwide despite differing geographies but emphasizing interconnected planetary systems driving them-the push internationally counter similarly linked interdependent risks much broader cross frontiers Read More:[DiscoverMagazine Lava.]!
