What Is Volcanic Eruptions? And Its Affects

What Is Volcanic Eruptions?

Volcanic eruptions are a beautiful sight. However, they are very dangerous. They add to cover about 80% of our planet’s surface. Additionally, volcanoes form over a long period. They can fall inactive, dormant, or extinct states. However, a volcano has a lifespan of about 10,000 years. Subsequently, each volcanic Eruption takes a long time to end. The session can take about ten years.

Additionally, we see the session can last for 100 years. The magma in the volcano, when erupted out, stands termed as lava. Here is some data you need to know about volcanic eruptions.

How Do Volcanoes Erupt?

We see that volcanoes are pressure points. The magma present in liquid form lies about 150kms deep. Additionally, the pressure under the surface is higher than usual. As time passes, an immense force builds up. Subsequently, the stress pushes the magma out of the volcano. They erupt with a huge blast. The magma pushes itself from the crust of solid rocks. The force inside forms a big Volcanic eruption. We see that pressure created under the surface of the earth is the reason. However, the outpour takes a long time to form. Also, volcanic eruptions last for a long time before dying away.

Identify A Volcanic Eruption

Before a volcano erupts, you can identify it. The massive release of gas is an indicator. Additionally, you can see ash pushed out soon after the lava comes out. The primary identification of an eruption is an unusual earthquake — subsequently, an emission of gas. The gas released takes varying shapes. It usually has a huge bulge. We see that predicting a volcano is hard. However, you can identify it by measuring the air for sulfur. It is a major volcanic gas that emits during an Eruption. The lack of instruments also leads to missing a volcanic prediction and warning.

Number Of Volcanic Eruptions

Across the globe, volcanoes erupt almost every day. The number ranges from 50-60 every month. Volcanic activity can fall into different states of mode. Subsequently, few show constant activity examples: Stromboli, Sakurajima, etc. However, individual Volcanic Eruptions occur very slowly. The period for Eruption lasts for an hour.

Additionally, the Eruption can range for weeks and months. An average volcano erupts at a rate of one time every 100 years. However, some can stay inactive for many years. An example is Masaya; the volcano is active every 25 years. However, it has stood not so keen for a long time.

Volcanic Eruptions: Do Volcanoes Affect?

Volcanoes stand as a hub of danger. However, It usually is the best place to find fossils. We see that sea animals can face a small amount of threat. Additionally, unlike humans and mammals, they can’t escape fast. We humans get a better chance to run before the lava flows. Once the magma bursts out, the lava has less energy. Sea animals can stand affected by the strong acid of volcanoes. The volcanic eruptions happen fast and take less time to give gases. Furthermore, it soon spreads to kill sea animals. Volcanoes also affect humans. The toxic gases can cause hard breathing problems and intoxication.
