About Volcanoes
  • Most volcanoes are formed when the boundaries of our planet's tectonic plates collide and overlap, eventually sinking deep inside.
  • Many get life by ‘hotspot volcanism’ which is the magmatic activity at the center of the tectonic plate.
  • Volcanoes have created the foundation of the land on our planet, crafting mountains, craters, soil beds and eventually making up to 80 percent of our surface.
  • About 1500 of them are active as of 2018.

75 percent of the active volcanoes of our planet are around the ring of fire, which is a horseshoe-shaped zone starting from South to North America, then moving towards Japan and New Zealand. Apart from the flowing molten lava, an active volcano produces avalanches of hot rocks, ash and toxic gas through superfast explosions.

The volcanic mudflows, or ‘lahars’ are capable of wiping out entire towns.

Scientists closely monitor volcanoes that are near a large population for signs of probable eruption, like increased gas emission. Like the weather, the signs can be misleading and unpredictable.

At least a dozen eruptions happen daily and increased network footprint and media coverage ensures that no such eruptions go unreported.

The 1815 Indonesian explosion in Mount Tambora is considered the largest and deadliest known volcanic eruption, killing 10,000 people right away and about 82,000 more eventually due to starvation and disease.
