The earth moved! Bizarre moment the ground wobbles under a walker’s feet as he jumps up and downby Phoebe Eckersley For Mailonline

A 21-year-old walker has been filmed bouncing on a bizarre snow-covered piece of 'moving earth' in Russia.
Denis Kislitsyn, from Moscow Oblast, Russia, was left shocked when the land beneath him began to tremble as he walked over it.
In the astonishing clip, the construction worker excitedly bounces back and forth as he tries to shake the unstable foundation.
He leaps into the air and lands heavily across the rugged terrain in his wellies and causes it to wobble below.
Unlike most bogs, this unusual one has grown over to create firm land at the surface, but the swamp underneath remains unsettled.
Fortunately, Denis knew what it was because there was a swamp underneath the grassland that he could see.
He said: 'It’s a swamp but you can walk on it as the grass is growing on it.'
The clip's 'moving' earth is a quaking bog as they develop over lakes or ponds with thick layers of vegetation, known as bog mats.
The bog mat, consisting of moss and shrubs, floats over a shallow pond which shakes when it is walked on.
A bog is sometimes formed when a lake slowly fills with plant debris.
In the Moscow Oblast area, there is a grass marsh and bog, especially in the Meshchera Lowland.
To the west of the region lies Vasyugan Swamp, the largest swamp in the northern hemisphere.
The wetland lies within the boundary of four regions of Russian Federation: Tyumen, Omsk, Tomsk and Novosibirsk.
