What happens if we drop a giant iceberg into a volcano? (“Cossss!” sure sounds)

From now on, if we close our eyes and think about this scenario, “kosss!” when a giant iceberg fell into the lava. We can guess it made noise, but what about after that?

We can all guess that fighting fire with fire just makes things worse, but What happens when a fiery volcano meets ice? Let’s take a closer look at that.

In 1973, local authorities in Iceland tried to stop the lava flow using the very cold sea water.

But 5 billion liters of seawater was not enough to stop the advancing lava. In this way, they could only slow down the flow of the lava. What if we tried to leave a huge piece of iceberg in the center of the volcano instead of pouring seawater into the lava?

Let’s start with a simple simulation. For example, Mount Michael in the South Sandwich Islands could be a sensible area. This mountain has bubbles and average temperatures of about 988°C to 1,279°C. It has a lava lake 110 meters wide. Since it is located in an abandoned area, life is also not possible.

We need an iceberg the size of a football field and a half to throw it into the lava lake on Mount Michael.

In 2017, a huge iceberg broke off the Antarctic Peninsula, and this iceberg was even bigger than Luxembourg. So from Mount Michael’s lava lake, That means it is 200,000 times larger.

Let’s throw this broken iceberg and most of it into the lava. Once we do this, the first thing we’ll see is: There will be a sudden burst of steam. The meeting of ice and lava causes the ice to instantly change from solid to gas, bypassing the liquid form. This is called sublimation.

Then two more situations can arise.

The ice turns to steam faster than it should, and this steam creates more pressure inside the volcano. It causes the mountain filled with lava to explode.

Also, hardened magma called tephra rises into the air and explodes, just like fireworks. The lava fragments scattered around can be the size of a house or a car.

Another possibility is that the ice cools the surface temperature of the lava. As the steam tries to dissipate, the lava appears to be boiling and hardening.

Again, when it comes to throwing an iceberg into a volcano, the hard crust inside traps the gas inside. Over time, the pressure of the compressed gas leads to an unpredictable explosion.

Basically, throwing an iceberg into an active volcano to stop a volcanic eruption, Given all these possibilities, it will only make the explosion worse.
