Can rain make a volcanic eruption?
Falk Amelung said, “We knew that changes in the water content in the Earth’s subsurface can trigger earthquakes and landslides. Now we know that it can also trigger volcanic eruptions. Under pressure from magma, wet rock breaks easier than dry rock. It is as simple as that.”
Which country has no volcano?
Answer and Explanation: Every continent on Earth has volcanoes, but Australia does not have any active volcanoes. They are all extinct, largely related to Australia not being near the edge of a tectonic plate or hot spot, so the volcanoes have moved away from their access to lava.

What if we poured concrete into a volcano?
The concrete plug would burst out too. The dust from concrete would lead to fatal lung diseases and cancer. The lava flow from a natural eruption is usually slow and predictable. Maybe a better plan would be to use the concrete to divert the flow away from towns and cities.
Can water cool down lava?
Water has been found to be the most practical means to achieve lava cooling. Water absorbs heat from the lava; even more so, if it heats up to the boiling point and changes to steam.
How hot is lava?
2,200 degrees Fahrenheit
Here are some temperatures recorded at different times and locations: The eruption temperature of Kīlauea lava is about 1,170 degrees Celsius (2,140 degrees Fahrenheit). The temperature of the lava in the tubes is about 1,250 degrees Celsius (2,200 degrees Fahrenheit).
