Block lava is a type of lava flow characterized by its rough, jagged surface made up of large angular blocks. This type of lava flow is typically associated with effusive eruptions from shield volcanoes, where the low viscosity of the lava allows it to move slowly and solidify into these distinct shapes.
When block lava erupts from a volcano, it cools and solidifies quickly on the surface while the molten lava underneath continues to flow. As a result, the outer layer of solidified lava breaks into large pieces, creating a blocky texture that is often compared to broken pavement.
Formation
Block lava forms when the outer layer of a lava flow cools and hardens before the inner lava can finish draining away, leaving behind a pile of solidified blocks. These blocks can range in size from a few inches to several feet in diameter and are typically angular in shape due to the rapid cooling process.
Characteristics
The distinctive appearance of block lava can vary depending on the type of lava erupting from the volcano. Some block lava flows may have a smooth, glassy surface, while others may appear more rough and spiky. The size and arrangement of the blocks can also vary, with some flows forming neat, organized stacks of blocks, while others create chaotic jumbles of rocks.
Examples
One of the most famous examples of block lava is the A'a lava flow on the Big Island of Hawaii. This flow, which is known for its sharp, jagged blocks and rough texture, is a popular attraction for tourists and geologists alike. Other examples of block lava can be found in volcanic regions around the world, including Iceland, Japan, and the Galapagos Islands.
In conclusion, block lava is a fascinating geological formation that provides valuable insights into the behavior of volcanoes and the properties of lava. By studying these unique lava flows, scientists can better understand the complex processes that shape our planet's surface.
