Usually, volcanic eruptions above water are the result of a magma-plume burning through a spot in the Earth's crust, or by the rising part of a magma convection cell. Such conditions are often found near the edges of the continental plates. There are also spots where the Earth's crust is so thin that magma breaks through even without there being a plume, such as near oceanic ridges. Most of the volcanic eruptions on this planet take place under water, near oceanic ridges.
What else can I help you with?
What is causing faulting?
Faulting is caused by the stretching or compression of rock by tectonic plate movements
Can tsunamis be caused by earthquakes in the ocean floor?
Tsunamis are usually triggered by earthquakes that occur at subduction zones. A subduction zone is where one tectonic plate slide under another.Tsunamis are also caused by landslides along the coastline, which may be triggered by earthquakes, and on rare occasion by meteors crashing into the oceans if they're of significant size.
A large seismic sea wave caused by a volcanic eruptions or earthquake?
A large seismic sea wave caused by volcanic eruptions or earthquakes is known as a tsunami. These waves occur when there is a sudden displacement of a significant volume of water, often due to tectonic activity. Tsunamis can travel across entire ocean basins at high speeds, and when they reach shallow coastal areas, they can grow to immense heights, causing devastating destruction. It's important to have early warning systems in place to mitigate the impact of such natural disasters.
seismometers?
instrument that respond to ground motions such as caused by earthquakes, volcanic eruptions and explosions
What natural disaster is caused by earthquakes but could also be caused by an asteroid?
earthquakes cause fires and tsunamis. earthquakes are caused either ice bergs falling down from somewhere e.g iceland or antarctica, or from the tetonic plates clashing together, or they go after volcanic eruptions
What are 2 causes of earthquake?
earthquakes can be caused by either tectonic or volcanic. Tectonic earthquakes are caused by movement of tectonic plates underneath the earth surface. Volcanic earthquakes are caused by volcanic activities underneath or above earth's surface.
Are volcanic eruptions caused by the separation of the tectonic plates?
yes and no. Volacanic eruptions '''can''' be caused by the '''seperation of plates''' but they can also be caused by the '''plates conliding with each other'''. It can push the magma upward
What causes both earthquakes and volcanic eruption?
Both earthquakes and volcanic eruptions are caused by movements in the Earth's crust. Earthquakes are triggered by the sudden release of energy along faults in the crust, usually from tectonic plate movements. Volcanic eruptions occur when magma rises to the surface and releases gases, causing pressure to build up until an explosive eruption occurs.
What is caused by the earths plate or crust?
Earth's plates or crust can cause earthquakes, volcanic eruptions, and the formation of mountain ranges due to tectonic plate movements and interactions. Subduction zones can also lead to the formation of deep ocean trenches and volcanic arcs.
What occurs when earths crust shift?
When the Earth's crust shifts, it can result in earthquakes, volcanic eruptions, and the formation of mountains or valleys. These movements are usually caused by the tectonic plates beneath the Earth's surface shifting and impacting one another.
What is the difference between a tectonic hazard and a tectonic event?
a tectonic hazard is a disaster caused by the moving of tectonic plates.....anda tectonic activity is the moving of tectonic plates........
What volcanic eruptions have caused travel troubles?
the volcanic eruptions in Europe they cant travel anymore
Shaking or trembling of the earth that is volcanic or tectonic is called?
Earthquake. It is a sudden and violent shaking of the ground caused by movements within the Earth's crust, either due to volcanic activity or tectonic plate motions.
What does seicmic activity mean?
Seismic activity refers to the vibrations and movements in the Earth's crust caused by the release of energy from sources such as earthquakes, volcanic eruptions, landslides, or human activities like mining or construction. Scientists use seismometers to measure and monitor these movements to better understand the Earth's tectonic processes and potential hazards.
What is the most likely cause of the volcanic and earthquake activity in this region?
The volcanic and earthquake activity in a region is usually caused by the movement of tectonic plates. When tectonic plates shift and collide, it can create volcanic eruptions and earthquakes due to the buildup of pressure and release of energy. The specific type of activity depends on the type of plate boundary present in the region.
What stress causes volcanoes?
Volcanoes are primarily caused by tectonic plate movements and the release of pressure from the Earth's mantle. Stress from these movements and pressure can lead to magma rising to the surface and resulting in volcanic eruptions. Other factors such as the composition of the magma and the presence of water and gases can also influence volcanic activity.
What is the most common cause of tsunamis?
Tsunami are waves caused by sudden movement of the ocean due to earthquakes, landslides on the sea floor, land slumping into the ocean, large volcanic eruptions or meteorite impact in the ocean.
