About Lava Fields
Lava fields, also known as lava plains or lava beds. are large and, barring any encroaching moss growth, barren expanses of ragged basalt lava flows whose molten march was long since halted by the forces of a flat ground. These fields often go on for miles, but geologists prefer to measure them in cubic kilometers, and having done so, concluded that the leader of the pack is Stóravítishraun at 30-50 cubic kilometers, closely followed by Trölladyngja at 20-30 and Þjórsárhraun at 26.
Lingo has it that these desolate vistas, or “monogenetic volcanic fields”, constitute collections of cinder cones and Maar vents amid their fellow lava flows and pyroclastic deposits and sometimes they center around a stratovolcano, whose molten earthen innards once popped like a boiling blackhead from the surface of the earth.
