Central eruption
Magma surges up along the tubular channel and overflows from the crater, which is called a central eruption. This center is generally at the intersection of the two groups of faults, and is the main way of volcanic activity in the Mesozoic, Cenozoic and even modern eras. A central eruption is often accompanied by a strong explosion, which first ejects a large amount of gas and debris, and finally overflows magma.
