Lava is molten rock that has erupted from a volcano. The temperature of lava can vary greatly, depending on the type of volcano and the composition of the lava. In this article, we will explore the factors that affect the temperature of lava and delve into some of the hottest types of lava ever recorded.
Before we dive into the world of lava temperatures, let's understand the concept of magma. Magma is molten rock that is found beneath the Earth's surface. When magma erupts onto the surface, it is called lava. The composition of magma and lava varies depending on the type of rock that melts. Factors such as the presence of certain minerals and gases influence the temperature and behavior of lava.
As we transition from the intriguing world of magma and lava composition to the main content section, we will delve deeper into the factors that influence lava temperatures and uncover the hottest types of lava known to humankind.

Hottest Lava Recorded: 1320°C (Nyiragongo, DR Congo)
Basaltic Lava: 1100°C - 1200°C
Basaltic lava is the most common type of lava on Earth. It is typically produced by eruptions from volcanoes that are located along plate boundaries, such as the Mid-Ocean Ridge and subduction zones. Basaltic lava is also found in intraplate volcanoes, which are volcanoes that are not located along plate boundaries. These volcanoes are often associated with hotspots, such as the Hawaiian Islands.
The temperature of basaltic lava can vary depending on the composition of the lava and the conditions of the eruption. However, basaltic lava typically ranges in temperature from 1100°C to 1200°C. This makes it one of the hottest types of lava on Earth.
Basaltic lava is typically very fluid and flows easily. This is because it has a low silica content. Silica is a mineral that makes lava more viscous and less fluid. The low silica content of basaltic lava also makes it more likely to produce lava flows that are extensive and can travel long distances.
Basaltic lava is a major hazard to human populations that live near volcanoes. Lava flows can destroy homes and infrastructure, and they can also cause wildfires. However, basaltic lava can also be a valuable resource. It can be used to create new land, and it can also be used as a source of geothermal energy.
Basaltic lava is a fascinating and powerful natural phenomenon. Its high temperature and fluidity make it a major hazard to human populations, but it can also be a valuable resource. By understanding the properties of basaltic lava, we can better mitigate the risks associated with volcanic eruptions and harness the potential benefits of this molten rock.
Andesitic Lava: 900°C - 1100°C
Andesitic lava is a type of lava that is intermediate in composition between basaltic and rhyolitic lava. It is typically produced by eruptions from volcanoes that are located in subduction zones, where one tectonic plate is pushed beneath another. Andesitic lava is also found in some intraplate volcanoes, particularly those that are associated with continental arcs.
The temperature of andesitic lava can vary depending on the composition of the lava and the conditions of the eruption. However, andesitic lava typically ranges in temperature from 900°C to 1100°C. This makes it hotter than rhyolitic lava but cooler than basaltic lava.
Andesitic lava is typically more viscous than basaltic lava. This is because it has a higher silica content. Silica is a mineral that makes lava more viscous and less fluid. The higher silica content of andesitic lava also makes it more likely to produce lava flows that are shorter and thicker than basaltic lava flows.
Andesitic lava can be a major hazard to human populations that live near volcanoes. Lava flows can destroy homes and infrastructure, and they can also cause wildfires. However, andesitic lava can also be a valuable resource. It can be used to create new land, and it can also be used as a source of geothermal energy.
Andesitic lava is a common and important type of lava. Its intermediate composition and temperature make it a significant hazard to human populations, but it can also be a valuable resource. By understanding the properties of andesitic lava, we can better mitigate the risks associated with volcanic eruptions and harness the potential benefits of this molten rock.
Rhyolitic Lava: 700°C - 900°C
Rhyolitic lava is the least common type of lava on Earth. It is typically produced by eruptions from volcanoes that are located in continental settings, such as the Andes Mountains and the Rocky Mountains. Rhyolitic lava is also found in some intraplate volcanoes, particularly those that are associated with hotspots.
- Composition: Rhyolitic lava is the most silica-rich type of lava. Silica is a mineral that makes lava more viscous and less fluid. The high silica content of rhyolitic lava makes it the coolest type of lava.
- Temperature: Rhyolitic lava typically ranges in temperature from 700°C to 900°C. This makes it cooler than basaltic and andesitic lava.
- Viscosity: Rhyolitic lava is the most viscous type of lava. This means that it flows very slowly. The high viscosity of rhyolitic lava makes it more likely to produce lava domes and flows that are short and thick.
- Explosivity: Rhyolitic lava is often associated with explosive eruptions. This is because the high gas content of rhyolitic lava can cause it to fragment and produce ash and pumice.
Rhyolitic lava can be a major hazard to human populations that live near volcanoes. Lava flows can destroy homes and infrastructure, and they can also cause wildfires. However, rhyolitic lava can also be a valuable resource. It can be used to create new land, and it can also be used as a source of geothermal energy.
Lava Flows: 800°C - 1200°C
Lava flows are one of the most common and recognizable features of volcanic eruptions. They are streams of molten rock that flow from a volcano onto the surrounding land. Lava flows can vary greatly in size, from small flows that cover only a few square meters to large flows that can cover many square kilometers.
The temperature of lava flows can also vary greatly, depending on the composition of the lava and the conditions of the eruption. However, most lava flows typically range in temperature from 800°C to 1200°C. This makes them one of the hottest natural phenomena on Earth.

However, it is important to remember that lava fountains can also be very dangerous. By understanding the risks associated with lava fountains, we can better protect ourselves from this natural hazard.
Lava Domes: 600°C - 900°C
Lava domes are mounds or hills of lava that are formed when viscous lava flows slowly from a volcano's vent and accumulates around the vent. Lava domes can range in size from small mounds a few meters high to large hills hundreds of meters high.
The temperature of lava domes can vary greatly, depending on the composition of the lava and the conditions of the eruption. However, most lava domes typically range in temperature from 600°C to 900°C. This makes them one of the hottest natural phenomena on Earth.
Lava domes are often associated with explosive eruptions, which are eruptions that produce large amounts of ash and pumice. The high gas content of this type of lava causes it to be ejected from the volcano's vent with great force, creating a mixture of lava fragments and ash.
Lava domes can be 매우 위험한 현상입니다. They can collapse suddenly, sending flows of hot lava and gas down the volcano's slopes. Lava domes can also release large amounts of volcanic ash and gas, which can pose a hazard to human health and infrastructure.
Lava domes are a fascinating and powerful natural phenomenon. Their unique shape and composition make them a popular tourist attraction. However, it is important to remember that lava domes can also be very dangerous. By understanding the risks associated with lava domes, we can better protect ourselves from this natural hazard.
Pahoehoe Lava: 1100°C - 1200°C
