What is the volcanic block?

Volcanic block is a solid piece of rock that has been excluded from the volcano during the eruption. The term covers rocks of different sizes, but the minimum size has a diameter of 2.5 inches (64 mm). Volcanic eruptions can be extremely strong, so the volcanic block can be very large, some measuring 16 feet (5 m) or more diameter. Sometimes they are confused with a different type of volcanic ejects, a volcanic bomb, which is a stain of material drained from the eruption in molten state rather than a solid rock. During violent eruptions, some volcanoes can throw volcanic blocks up to a few kilometers away. Many volcanic blocks are simply pieces of surrounding rocks that are broken and released by the violence of volcanic eruptions. These rocks can have almost any type and composition. More often, however, these rocks are part of the volcano itself and can be part of old magmatic tunnels, stiff lava from older eruptions or parts of the wall of the main ventilation opening, which is the primary point of ejection of magma from inside the volcano.

It is important to understand the difference between the volcanic block and the volcanic bomb. The volcanic block is a rock that existed before the volcanic eruption was released, while the volcanic bomb is a rock that is released from the volcano. Volcanic bombs most often or completely solidify before they hit the ground, which sometimes causes them to be confused with volcanic blocks.

geologists and vulcanologists use several means to distinguish volcanic bombs from volcanic blocks, but the shape is the simplest method. Typical volcanic bomb tends to have an elongated shape and can have relatively smooth surfaces, while the soperablok tends to have angular surfaces that are characteristic of broken or broken rocks. The basic shape of the volcanic block is also more spherical than the volcanic bomb, although it is only a tendency and volcanic blocks with other shapes are not unusual. Scientists study volcanic blocks and their scattering to learnAbout volcanoes, their eruptions and their history.
