அமெரிக்க மனிதர் தனது தோட்டத்தில் எரிமலை குழாய் கீழே விழுந்து இறந்துவிட்டார்
A man in Hawaii has died after falling down a “lava tube” – a tunnel formed by volcanic eruptions – while trimming trees on his property.
Police say the 71-year-old had apparently fallen about 22ft (7m) “through a soft area of ground”.
Lava tubes are formed when lava cools and hardens on its top layer but continues to drain and cool beneath.
Police say the man was found on Monday after friends reported that they had not heard from him for days.
Hawaii Police Department Major Robert Wagner told Big Island Now that the shaft the man fell into was approximate two feet (60cm) wide.
Fire crews abseiled into the chasm to recover the body.
Unlike slower forming geological features, like caves and caverns, lava tubes are often formed in days and weeks, according to National Geographic.
As that lava flows and drains into the ocean, it leaves behind maze-like tunnels – some of which are over 40 miles long.
