Seismologists investigating undersea earthquakes have found that molten rock lubricates faults. This decreases the amount of friction between sides of the fault and decreases the intensity of earthquakes. They also found that the fragmentation of fault lines along the seafloor contributes an earthquake-dampening effect.

I think you've mis-read your source. The earthquakes are undersea because they are on the subduction thrust plane between a sinking ocean-floor plate and the continent above it, under the continental shelf. The lubricant is not molten rock but wet sea-floor sediment, but the friction does help the Aesthenosphere heat partially the subducting basalt, with the water also acting a flux to help the melting.

Can earthquakes happen under water?
Yes, earthquakes can happen underwater. When an earthquake occurs beneath the ocean, it can cause a tsunami if the magnitude is strong enough to displace a significant amount of water. Underwater earthquakes are monitored by seismologists to assess the potential risk of tsunamis.
What is a underwater earthquake?
An underwater earthquake is a seismic event that occurs beneath the Earth's surface in the ocean. These earthquakes can result in the movement of tectonic plates, which can generate tsunamis due to the displacement of water. Underwater earthquakes are monitored using seismometers and can vary in magnitude and impact.
Do most earthquakes occur on land or water?
The most earthquakes are mostly occurs on land
What is it called when an underwater earthquakes can cause huge ocean waves?
It is called a tsunami. Tsunamis are generated by underwater earthquakes, volcanic eruptions, or landslides that displace large volumes of water, creating massive waves that can travel across oceans at high speeds.
What happens when an earthquake takes place underwater?
When an earthquake occurs underwater, it can generate a tsunami if the seismic activity displaces a large amount of water. These tsunamis can travel long distances at high speeds and cause significant damage along coastlines. Underwater earthquakes can also trigger underwater landslides or volcanic eruptions.
Can hurricanes and earthquakes happen underwater?
Hurricanes do not form underwater, as they require warm ocean water. Earthquakes can certainly occur underwater, known as underwater earthquakes, and can trigger tsunamis due to the displacement of water.
What are 3 underwater names that can cause tsunamis?
Underwater landslides, Underwater volcanic eruptions, and Underwater earthquakes
Can earthquakes happen underwater?
Of course! In fact, underwater earthquakes are a major cause of tsunamis.
Could earthquakes occur underwater?
Yes, they do.
Why are tsunamis associated with earthquakes?
Well, earthquakes do cause tsunamis. But only underwater earthquakes. Plus, they have to be a transform plate boundary earthquake(caused by subduction).Any displacement of water will cause a tsunami. In short, some underwater earthquakes cause tsunamis.
Underwater earthquakes of a great magnitude can create what?
tsunamis
Can you have earthquakes under water?
Yes, earthquakes can occur underwater, causing what is known as a tsunami. These underwater earthquakes are typically caused by the shifting of tectonic plates beneath the ocean floor. The resulting seismic waves can generate powerful underwater disturbances that propagate to the surface.
Underwater earthquakes may cause which of the following?
Tsunamis' can be formed after an undersea earthquake.
Do all countreis have earthquakes?
Yes, but most happen underwater.
What causes underwater earthquakes and or vocanoes?
faults and plates disturbances
Who is responsible when there is a Tsunami?
An earthquake is responsible 'cause underwater earthquakes cause tsunamis.
Can earthquakes happen under water?
Yes, earthquakes can happen underwater. When an earthquake occurs beneath the ocean, it can cause a tsunami if the magnitude is strong enough to displace a significant amount of water. Underwater earthquakes are monitored by seismologists to assess the potential risk of tsunamis.
