In a nutshell, earthquakes are sudden instances where the land of any particular or all places starts trembling at some speed. And, Volcanoes are the places where magma is present. These are primarily present under the tectonic plates since they either converge or diverge, causing heat and then magma – Moreover, several types of volcanoes landforms are created such as Caldera and flood basalt provinces, etc. The concept is broad enough; let’s discuss it in detail.
Volcanoes and Earthquakes
Volcanoes: The Volcano is a hole in the Earth’s crust that is the way of releasing molten lava during an eruption. When this happens, all the areas nearby the volcano tremble. Not all these volcanoes are explosive. They form some landforms based on their explosive nature. If they are explosive, then they form mountains. But on the other hand, if they are not explosive, they are responsible for forming the plateau.
Based on their eruptions’ activity, they are of various types:
- Shield volcanoes
- Cinder cone volcanoes
- Composite volcanoes
- Caldera
- Flood Basalt Provinces
- Mid-Ocean Ridge Volcanoes
Earthquake: The point inside the world’s hull where a quake starts is called the concentration or hypocenter or seismic concentration.
- Earthquakes are trembling the Earth’s crust. This all happens due to energy releases, which further produces different waves (or seismic waves) that travel in all directions.
- The waves produced during an earthquake are known as seismic waves.
- Researchers or scientists use seismographs to measure every activity of these seismic waves.
- The area beneath the earth’s surface where the seismic tremor begins is known as the hypocenter, and the area straight above it on the outer layer of the Earth is known as the focal point or epicentre.
Distribution of Earthquakes and Volcanoes:
Distribution of Earthquakes
There are a few spots where these tremors are restricted to that district, as it were. There is no exact location of earthquakes, and they can occur at any location. But still, there are some patterns earthquakes follow, let’s see, what are they?
Circum-Pacific seismic belt – This is the region where you can find the Earth’s largest waves (or earthquakes). That is why this area is additionally named the “Ring of Fire.”
Alpine earthquake belt – This belt goes from Java to Sumatra via the Himalayas and experiences approx. Seventeen per cent of the world’s earthquakes.
Submerged mid-Atlantic Ridge – This ridge is also experiencing divergent plate boundary earthquakes, where both tectonic plates are separated.
Distribution of Volcanoes:
The plate tectonics hypothesis explains the worldwide conveyance of volcanoes. The spring of gushing lava on the worldwide guide is disseminated at the accompanying speeds.
Circum Pacific belt – This region is responsible for experiencing 2/3 of the world’s volcanoes. This is located in the Pacific Ocean’s coastal areas. This region is found near divergent boundaries, where mostly volcanic activity is found.
Mid-Continental belt – This belt includes volcanoes like – Stromboli, Etna, Vesuvius, etc.
The belt is within the united plate limits. One piece of this belt comes towards the African valley and another branch towards the Caucasus and Himalayas.
Mid-Ocean belt – The mid-ocean belt is parallel to or corresponds to the Atlantic Ocean’s Ridge. And it includes the volcanoes – St. Helena and The Antilles.
Difference Between Earthquake and Volcano:
Earthquakes and Volcanoes both phenomena are related to tectonic plate movement. But despite this, these two phenomena have some differences, which we discuss below:
| Earthquake | Volcano |
| The seismic tremor (or earthquake) is a severe trembling of the Earth’s surface, leading to plates’ movement. Developments in Earth’s peripheral layer bring about the shaking. The shaking is brought about by developments in Earth’s peripheral layer. | The volcano can be referred to as the byproduct of an instance when one tectonic plate underneath another plate merges and leads to the formation of lava, which releases from the opening. |
| Hard to predict due to their unusual patterns. | Easy to predict. |
| Earthquakes are responsible for the release of seismic waves. | After the volcano burst, magma or lava was released, which further led to the formation of new rocks. |
| Earthquakes lead to the destruction of the Earth’s crusts. | Volcanoes lead to the formation of new Earth’s crusts in the form of cold lava or magma. |
| This phenomenon occurs inside the Earth’s surface (or Earth’s crust). | This phenomenon occurs at the Earth’s surface. |
Conclusion:
That’s the wrap topic Description of Earthquake and Volcano.
So far, we discussed the topics of earthquakes and volcanoes deeply.
An earthquake is a severe instance where the land starts trembling and shaking suddenly. It can take place anywhere around the world and cause destruction too.
On the other hand, volcanoes are predictable most of the time, and it is where a tectonic plate has magma inside; the place through which it is released is called a volcano. Moreover, since the volcano eruption is predictable, practices can be done accordingly to avoid destruction.
