Severe tremors were felt on Sunday at Kamchatka near Kuril Island in the eastern region in Russia.
The earthquake once again occurred in Russia on Sunday (3 August 2025). In the eastern region of the country, a strong tremors were felt in Kamchatka near Kuril Island. The intensity of this earthquake has been measured at 6.7 on the Richter scale. After this, a tsunami warning has been issued in the country. This has increased difficulties in Russia. This is the same area where an earthquake of 8.8 magnitude occurred last week. After this, there was a possibility of tsunami in many countries. With this, for the first time in Russia, a volcano has been exploded for the first time in the last 600 years.
In such a situation, the question arises whether the volcano also causes an earthquake or tsunami? What will be the effect of this volcano? Let’s try to know.
When does a volcanic explosion occur?
In fact, volcanic explosion occurs when molten lava (magma), gases and ash rise rapidly under the surface of the earth and start exiting the surface of the earth. At the same time, the earthquake is felt when the tectonic plates of the earth either hit each other, slip under each other or move around.
Earthquake can occur due to volcano
Both volcanic eruptions and earthquakes are natural phenomena occurring on the surface of the earth. They are often related to each other. Then along with volcanoes, earthquakes are also associated with the plates and tectonic movement of the earth. In such a situation, the speed of magma and pressure of gases inside the volcano can cause earthquake. Therefore, we can say that earthquake can occur due to volcano.

In fact, when the magma of the volcano moves rapidly towards the surface, its speed puts pressure on the rocks. The rocks can break due to this pressure, which can cause earthquakes. Apart from this, even if the speed of magma and gases is very high during the volcanic eruption or during the explosion, there is a possibility of earthquake. However, there is a difference in earthquakes and tectonic earthquake caused by volcanoes. The cause of the earthquake caused by volcanoes is pressure on the plates of magma and gases. At the same time, tectonic earthquake is caused by the tectonic plates.
Volcano can also be the cause of earthquake in Russia
As far as the earthquake in Russia is concerned, experts say that it can be related to the torn volcano for the first time in more than 600 years in the eastern region of the country. It is being told that the ash was about six kilometers from the volcano of Kaschka. In such a situation, the earthquake of 8.8 magnitude last week and the 7.0 magnitude earthquake on August 3 could be the result of this.
Tsunami may come due to volcano
After the volcanic explosion in Russia, there is a possibility of tsunami in three areas of Kamchatka. Apart from this, Russia’s RIA State news agency and scientists have also feared that a tsunami may come up to French Polynesia and Chile. Earlier, even after a fierce earthquake, Russian scientists had feared that earthquakes may occur in this area for the next few weeks.
Earthquake caused havoc in Russia
Not one, two volcanic explosions in Russia
Russia has actually occurred not one, not two volcanic explosions. For the first time after 600 years in Kamchatka, there was an explosion in the Crasninicov volcano. The air space has been discontinued in the region due to the spread of an ash of up to six thousand meters high due to an eruption in the 1856 meter height Crasninicov volcano. Earlier, on Wednesday (July 30), there was also an explosion in the Cluchevskaya Sopka volcano of the Kamchatka Peninsula. While crushaninikov volcanic slept, Sopka volcano is the most active volcano not only in Europe but also in Asia. Experts believe that the earth in Russia will be shocked due to eruption in both these volcanoes.
Why Crusheninicov volcano erupted in Russia?
Scientists say that both these volcanoes have occurred in the area of Russia, which is located near the ring of fire. The ring of fire is an area where Oceanic tectonic plates are also located along with many continents. When these plates collide with each other, the volcano burst, an earthquake comes or a tsunami. In such a situation, there is every possibility that the Crasninicov volcano must have been calm for so long, because the intensity of its magma and gases would not have been so much that we can explode. They must have got a chance to get out of collision and there would have been an explosion in the volcano.
According to Olga Girina, the chief of the RIA and the Kamchatka volcanic eruptions, Olga Girina, the final known explosion in the Crasninicov volcano occurred within 40 years of the year 1463. After this, no explosion was revealed in this volcano. After so many years, it has exploded once again.
