Interactive demonstration of volcanic outgassing and geological processes

๐Ÿ”ฅ Volcanic Eruption Simulation

Observe the volcano's eruption, lava flow, and ash cloud.

๐Ÿ”ฌ Volcano Structure

Magma chamber

Molten rock reservoir (magma chamber) at depths of 5-50 km below the surface. Magma contains dissolved gases and mineral crystals. When pressure increases, magma rises to the surface.

Volcanic channel

Tube connecting the magma chamber to the crater. Through it, magma rises to the surface. The channel can be vertical or inclined, depending on the geological structure.

Crater

Pit-like depression at the summit of a volcano through which lava, ash, and gases are ejected. The crater can have a diameter from several meters to several kilometers.

Volcanic cone

A mountain formed from erupted materials (lava, ash, bombs). The cone shape depends on the type of eruption and lava composition. It can be a shield volcano, stratovolcano, or cinder cone.

โšก Types of Volcanic Eruptions

Hawaiian type

Quiet eruptions with rare basaltic lava. Lava flows from fissures and craters, forming wide streams. Little ash, mostly gases. Examples: Hawaiian volcanoes.

Strombolian type

Explosive eruptions with viscous lava. Characterized by periodic explosions that eject lava bombs and ash. Form slag cones. Example: Stromboli volcano.

Pliny type

Most powerful eruptions with very viscous lava. Create high ash columns (up to 50 km), plastic flows, and lahars. Examples: Vesuvius (79 AD), Krakatoa (1883).

Pelissky type

Eruptions with very viscous lava that forms lava domes. Characterized by ash ejections and pyroclastic flows. Example: Mont Pelรฉ volcano.

โ“ Frequently Asked Questions

Why do volcanoes erupt? +

Volcanoes erupt due to tectonic plate movement, creating pressure in a magma chamber. Dissolved gases expand in the magma when heated, increasing pressure. When pressure exceeds rock strength, eruption occurs.

Can we predict volcanic eruptions? +

Yes, modern methods allow predicting failures weeks or months in advance. Symptoms: earthquakes, surface uplift, changes in gas composition, increased temperature. Monitoring is conducted via seismometers, GPS, gas analyzers.

What is the difference between magma and lava? +

Magma is a molten rock beneath the Earth's surface containing dissolved gases. Lava is magma that has reached the surface and lost most of its gases. Lava cools quickly and solidifies, forming volcanic rocks.

Are volcanoes beneficial? +

YES, volcanoes bring many benefits: fertile soils, useful minerals, geothermal energy, tourism. Volcanic rocks are used in construction. Volcanoes also regulate climate by releasing gases into the atmosphere.

Where are the most active volcanoes located? +

The most active volcanoes are located in the 'Ring of Fire' around the Pacific Ocean, where tectonic plates meet. Other active zones include Hawaii Islands, Iceland, East Africa. The most active volcano is Kilauea on Hawaii.
