š What makes a volcano erupt?
Beneath Earthās surface, intense heat melts rock into magma. Over time, this molten rock builds up in underground chambers, creating pressure. As the pressure rises, the ground may swell, and earthquakes may shake the area ā these are the warning signs of an impending eruption.
When the pressure becomes too great, the magma bursts through the surface as lava, gas, or ash.
ā¢ Shield volcanoes (e.g., Mauna Loa, Hawaii) erupt with flowing lava
ā¢ Stratovolcanoes (e.g., Mount Semeru, Indonesia) explode violently with ash and rock
We canāt stop volcanoes from erupting ā but monitoring, early warning, and preparedness save lives.
