geological phenomenon

This is the bizarre moment the soil turned into liquid, swallowing an excavator and the driver had to jump out to escape.

This phenomenon occurs when stones of the same size are pushed together in large numbers down the slope, causing them to move like liquid.

The world's longest continental volcanic chain discovered in Australia has a total length of up to 2,000km.
