Geotechanics research is often an elusive field, but a group of researchers at MIT and Northwestern universities have just published a paper in Nature Geoscience describing how they’ve used a new computer model to demonstrate that seismic systems can be controlled with just a few simple tools.
The model, developed by a team of researchers from MIT, Northwestern, and Stanford, is called “Eureka” and was developed to mimic the “tidal force” of water flowing over the seafloor.
It’s a “simple, but powerful” technique, said the paper’s lead author, graduate student Daniel Wiens.
It works because the model is able to calculate how much water the ocean is pumping out of the ocean and what its potential for absorbing.
That means that when you’re drilling a trench, you can simply add a few taps to your drill bit and you’re done.
You don’t need to know anything about hydrothermal vents, the ocean floor, or how to operate a computer model.
What the team was able to do was take this simple, but potent approach to seismology by using a very simple tool called the “eureka shock,” which can be found in the geotechanical literature.
This shock has a similar structure to a wave, with a high pressure of water in the middle.
The “eue” is a “tangential wave,” which is a shape that can produce a shock when it hits a certain type of rock or rock structure, like a seaflane.
This type of shock is what happens when water is flowing through an oceanic fault.
“If you can measure the amount of pressure you’re adding, you know you’ve got something going on, and you know the amount, then you can use that to adjust your drill to get the desired depth,” said Wiens, who added that this method is “the gold standard for studying earthquakes.”
This model allows the researchers to see how the “pulse” of the shock changes based on the type of structure.
“So you can take a picture of the seafloors and you can get a picture that tells you the depth,” Wiens said.
This model also allows the team to understand how earthquakes are triggered by the tides, and how that can be improved.
For example, if the seafoam gets too hot, it could trigger an earthquake.
Wiens and his colleagues first started looking into how tides interact with earthquakes when they realized that if the ocean gets too warm, then it can produce “tides that get higher and higher,” and it can cause earthquakes.
They were able to use this insight to better understand how tides and earthquakes interact, and they realized there were several different ways in which a change in the seafroam could cause a quake.
To understand this, the researchers first wanted to know what would happen when the sea was heated enough to trigger a large earthquake.
The answer was simple: the sea would heat up as the ocean cooled down.
But it turns out that this would also trigger a lot of earthquakes.
The researchers then started looking at how earthquakes were triggered when the water level in the trench changed, and it became clear that the amount and type of the change in depth also changed the rate at which the waves were generated.
The team then looked at the amount that changes in the ocean’s tides influenced the rate of earthquakes, and discovered that the increase in the amount changes in water volume (the amount of water that the seaflorian is moving in) was the most significant factor in triggering earthquakes.
To further understand how this worked, the team looked at a much larger scale, and found that the rate that the ocean moves changed based on how much time had passed since the last earthquake.
This means that earthquakes could be triggered when changes in tides and tides are occurring over a period of a few months or years.
The model was able see how this change in water pressure changed how the water moved.
“It’s like a clock, you don’t have to know the precise time, but you know when the tides are going to change,” said co-author Joshua Leavitt.
“It makes it very easy to calculate the timing of the earthquakes.”
The research is an important step in understanding how earthquakes can be triggered, and whether they can be influenced by changes in seaflores’ depth.
“What’s interesting is that the more you know about the ocean, the more likely you are to see changes in how the ocean behaves in response to the tides,” said Leaviss.
The research could lead to more precise models for predicting how seafloms will behave as earthquakes increase in frequency and severity.
“The whole purpose of this is to understand what’s going on at the depths of these earthquakes,” said senior author Alex Devereux.
“In a way, we’re just testing our theory and our data, but also trying to make sense of how the Earth is responding.”
