Strohn Lava Bomb

Next to the so-called "lava bomb", which is not a real one, there are a handful of real lava bombs, most of which are no bigger than a grilled chicken.

A real lava bomb and a not so real one. Interesting to see them in real life.

When workers in the Wartgesberg quarry carry out an explosion in 1969, they are amazed! A round chunk of five meters in diameter broke away from the middle of the quarry wall. A lava bomb? Even experts are not sure at first, because it is difficult to imagine that the volcanic forces of the Eifel were sufficient to throw 120 tons through the air.A core drilling brings clarity: During the eruption of the Wartgesberg volcano, a piece of rock broke loose from the crater wall and rolled into the vent. Similar to a snowball, which gets bigger and bigger as it rolls down a slope, the chunk rolls through magma that sticks to its surface. With the next eruption, the ball is ejected again and then rolls down again. This is repeated a few more times until the sphere is buried by the crater wall, only to reappear many thousands of years later.
