Earthquake forming a volcano

[caters]

In my story about a planet called Kepler Bb(B flat like in music). It has 4 moons and orbits around a double binary star. In the 11th chapter I have an whole sequence of earthquakes in the same area that lasts for hours. Then after the earthquakes stop somebody checks the fault line and it is deep and hot. Because of this a volcano might form.

Now my humanoids have a mainly underground civilization and all those earthquakes didn't affect the homes other than it being dusty but it made all the tunnels between homes and buildings collapse.

400 people with the power of flight form groups of 4 and evacuate everyone.

As the geologist suspected a volcano formed in the place where they have been living for hundreds of years. The homes and buildings were like lava tubes.

But could it actually happen here on Earth or any other real earth-like planet that a major earthquake followed by more earthquakes in the same area could make the fault line so deep that lava starts to flow out of it and a volcanic ridge forms regardless of whether it is underwater or inland?

I know that there are volcanic earthquakes. They normally can't be felt but a seismograph can sure tell when the volcano is likely to erupt in the short term by measuring how strong the earthquake is.

I also know that occasionally a major earthquake in an area with active volcanoes will trigger the active volcanoes to erupt, even without an earthquake from the volcanoes themselves that usually happens before the eruption. An example of this is a 7.2 magnitude earthquake on the big island of Hawaii on November, 29, 1975 that was immediately followed by a short lived eruption from Kilauea.

But can earthquakes cause volcanoes to form?

Its more likely the subterranean activity caused both the earthquake and the volcanic activity.

It is possible for earthquakes to cause volcanoes to form, but it is not a common occurrence. In most cases, volcanoes are formed by the movement of tectonic plates or hotspots in the Earth's crust. However, there have been instances where earthquakes have triggered volcanic activity.

One way this can happen is if an earthquake causes a change in pressure or stress on a magma chamber, causing it to erupt. This is what happened in the example you mentioned on the big island of Hawaii. The earthquake caused a shift in the magma chamber, leading to an eruption.

Another way earthquakes can cause volcanoes to form is through the process of "earthquake swarms." These are clusters of small earthquakes that occur in the same area over a short period of time. These swarms can sometimes indicate that magma is moving towards the surface, which can eventually lead to a volcanic eruption.

However, it is important to note that these occurrences are rare and unpredictable. In most cases, earthquakes and volcanoes are not directly related and do not cause each other. So while it is possible for a major earthquake to trigger a volcanic eruption, it is not something that can be expected to happen on a regular basis.
