What else can I help you with?
Did the mt st Helen's eruption affect the land around it?
There is always earthquakes when volcanoes erupt, so, yes.
Is a seismometer used for earthquakes or volcanoes?
As magma, or molten rock, moves underground it creates earthquakes. The signature of magma-driven seismic waves is different from that of normal tectonic earthquakes. With multiple seismometers it is possible to determine where earthquakes are and whether or not they are migrating. If earthquakes are moving closer to the surface and closer to a volcano, that is a sign it might be getting ready for an eruption.
Are a dormant volcanoes still dangerous?
Yes. Even without an eruption a dormant volcano may be prone to earthquakes, landslides, and gas emissions.
Are Earthquakes and volcanoes are important for the formation of island chains?
Yes, earthquakes and volcanoes are important for the formation of island chains. Volcanic activity creates new land through the eruption of lava and ash, leading to the formation of islands. Earthquakes are also generated by the movement of tectonic plates beneath the Earth's surface, which can contribute to the formation and shaping of island chains.
Are volcanoes formed by earthquakes?
Volcanoes are not formed by earthquakes. Volcanoes are created by magma rising from the Earth's mantle through the crust. Earthquakes, on the other hand, are caused by the shifting of tectonic plates beneath Earth's surface. Volcanic activity can sometimes trigger earthquakes, but they are not the main cause of volcano formation.
How high does it have to be on the Richter scale to cause a volcano eruption?
Earthquakes do not cause volcanoes. However, magma moving to the surface rapidly can produce tremors. Volcanoes can cause earthquakes, but not vise-versa.
How are volcanoes earthquakes and tsunamis related?
A volcanic eruption can cause an earthquake and an earthquake underwater can cause a tsunami.
Do earthquakes cause volcanoes to explode?
In most cases, no. However, there is evidence that, on a few occasions, earthquakes appear to have triggered eruptions, most likely by disturbing the magma chamber beneath the volcano. Earthquakes often precede a volcanic eruption, be these are not the cause of the eruption, but are rather a result of the movement of magma that leads to an eruption.
Did the mt st Helen's eruption affect the land around it?
There is always earthquakes when volcanoes erupt, so, yes.
Are volcanes bad or earthquakes?
Both are considered bad. Volcanoes, if the eruption is big enough, can damage a lot of land. However, earthquakes are more frequent and they can be very destructive.
Why do you study earthquakes and volcanoes together?
You study these together because sometimes an earthquake is the cause of a volcano eruption and vice versa.

Yes. Even without an eruption a dormant volcano may be prone to earthquakes, landslides, and gas emissions.
What causes earthquakesand volcanoes to happen?
The earths plates rub together causing vibrations in the earth. Making Earthquakes If these plates are near volcanoes the friction will melt the magma causing a volcanic eruption.
How do earthquakes patterns?
the earthquake pattens are followed on the Richter scale it is also measured on different scales of matter. composite volcanoes do not have a violent pattern of eruption's.
What is the magnitude of nevado del ruiz volcano?
The Richter scale is applied to earthquakes, not volcanoes. The 1985 eruption was a VEI 3 on the Volcanic Explosivity Index.
What is the types of volcanoes eruption?
Volcanoes that erupts are known as active volcanoes.
