Jakarta –
Not long ago, satellites discovered that the world’s largest volcano had finally erupted for the first time in decades. The mountain in question is Mauna Loa in Hawaii.
According to the Space page, Mount Mauna Loa released incandescent lava at the end of November 2023, since its first eruption in 1984. According to authorities in Hawaii, the incandescent lava that came out is still under control and does not threaten property.
But what exactly is incandescent lava and how is it different from magma?
What is Incandescent Lava?
Lava is a term that comes from Italian and possibly also comes from the Latin word, namely labes, which means falling or sliding, as quoted on the MAGMA Indonesia page.
The first use of the term lava was recorded in 1737 in a description of the eruption of the Vesuvius volcano recorded by Francesco Serao.
Serao described the fiery flow as a comparison to the flow of water and mud that flows down the slopes of a volcano after an eruption.
In general, lava is magma ejected from within a terrestrial planet, such as the Earth or the moon, towards its surface. The process of releasing lava can occur through volcanic eruptions or through cracks in the Earth’s crust, both on land and below sea level.
Its liquid and hot nature makes it an important element in the formation and change of natural landscapes.
Quoted from Detik news, lava is explained as the result of expulsion of magma that appears on the Earth’s surface. When magma cools and hardens after coming to the surface, it turns into igneous rock known as basaltic. On the other hand, if lava mixes with material around the volcanic crater, the name becomes lava.
So, it can be concluded that incandescent lava is liquid magma that is emitted from a volcano in a burning state when an eruption occurs.
Usually, incandescent lava is a flow of melted incandescent volcanic rock with temperatures ranging from 700-1200 degrees Celsius which will burn anything in its path, as quoted from the book “Social Aspects of Lava Floods” by Sri Rum Giyarsih.
Difference between Lava, Magma and Lava
If lava is molten magma that comes out onto the Earth’s surface, then magma is a natural material that is in a liquid or semi-liquid phase, being the origin of all types of rocks that form on the surface of terrestrial planets.
Magma is usually found in layers below the Earth’s surface. However, evidence of magma has also been detected on other planets and some of the planet’s natural satellites.
Meanwhile, there is another term known as lava, which is a term that includes a mixture of river water and pyroclastic material.
Lahars can occur in three conditions, namely normal river flow (with sediment less than 30% of the total mixture), hyperconcentrated flow (with sediment between 30 and 60%), or debris flow (with sediment more than 60% of the total mixture).
