The Earth’s largest active volcano, located in Yellowstone National Park, USA, is actually a supervolcano capable of causing a catastrophic eruption.

Volcanoes can be monitored using various technologies, including seismometers, gas analyzers, and satellite imagery.

Some volcanic eruptions can have positive effects, such as enriching the soil with minerals and creating fertile agricultural areas.

Volcanoes are not just limited to Earth. Exoplanets in other star systems have also shown evidence of volcanic activity.

The word lava comes from the Latin word lavare, which means to wash.

Volcanoes can create impressive natural fireworks when they emit glowing lava bombs and release plumes of ash into the sky.
