🌊 In the case of this particular flow, a skylight over the lava tube provided a spectacular view of a rapidly moving lava stream.
❓ The video also explores the cause of the collapse of the lava tube's roof, leading to the formation of skylights.
00:01:11 Explaining the formation of a lava flow skylight and estimating the rapid flow of lava within the skylight as 1-2 meters or yards per second.
🌋 The skylight was surrounded by a thin crust, causing it to collapse.
🔥 The speed of the flowing lava in the tube was estimated to be 1-2 meters per second or 1-2 yards per second.
⏩ The conversion of the lava speed from meters per second to miles per hour was not mentioned.
