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 site, since its first eruption in 1984, Mount Mauna Loa has released glowing lava in late November 2023. According to authorities in Hawaii, the hot lava leak is still under control and does not pose a threat to property.
But what exactly is glowing lava and how is it different from magma?
What is glowing lava?
Lava is a term that comes from Italian and may also come from the Latin word labes, meaning to fall or slide, as quoted on the MAGMA Indonesia page.
The first use of the term lava was mentioned in 1737 in a description of the eruption of the Vesuvius volcano recorded by Francesco Serao.
Serao described the fiery stream as comparing it to the river of water and mud that flows down the slopes of a volcano after an eruption.
In general, lava is magma that is ejected from the interior of a terrestrial planet, such as the Earth or the Moon, toward 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.
Due to its liquid and hot nature, it is an important element in the creation and modification of natural landscapes.
Quoted from Detik news, lava is explained as the result of the ejection of magma that appears on the earth’s surface. As magma cools and hardens at the surface, it turns into igneous rock known as basalt. On the other hand, when lava mixes with material around the volcano’s crater, the name becomes lava.
It can be concluded that glowing lava is liquid magma that comes out of a volcano in a burning state during an eruption.
Usually, red-hot lava is a flow of molten, red-hot volcanic rock with temperatures between 700 and 1200 degrees Celsius that burns everything in its path, as quoted from the book “Social Aspects of Lava Floods” by Sri Rum Giyarsih.
Difference between Lava, Magma and Lahar
If lava is molten magma that erupts onto the Earth’s surface, then magma is a natural material that is in a liquid or semi-liquid phase and is the origin of all types of rocks that form on the surface of terrestrial planets.
Magma usually occurs in layers below the Earth’s surface. However, evidence of magma has also been discovered on other planets and some of the planet’s natural satellites.
There is now another term called lava, which includes a mixture of river water and pyroclastic material.
Lahars can occur under three conditions: normal river flow (with sediments less than 30% of the total mixture), hyperconcentrated flow (with sediments between 30 and 60%), or debris flow (with sediments more than 60% of the total mixture). ).
