What can we hope to get from the CORK? I’d like to explore the path from initial goals developed by Earl Davis (pictured above with the ACORK instrument package on the bench to his right) and his team and what can be hoped to be derived from the data from this and other CORK installations.

If you look at the picture that accompanies this blog, you will notice that just to the left of the Louisville seamount trail is a dark blue line that runs all the way down to New Zealand. That line is a boundary. To the left of it all the volcanoes (and there are a lot of them) are in the Pacific Ring of Fire.

Someday, seventy million years from now when the cockroach people are the dominant species on the planet, they are going to have their own marine research drilling program and are going to be drilling on a seamount whose top is 1,500 meters below the surface, and are going to be surprised when they discover a sedimentary core that has a Don Ho record in it, because it turns out the seamount is

In school, students learn the basic facts of plate tectonics. They usually can tell you that there are something called plates that cover the Earth’s surface. They also know that when plates come together the interesting things happen. They may mention earthquakes and volcanoes. They might recall that subduction or convergence is when one plate moves under another.

The Indian and Australian Plates plow northeast into the Sumatra subduction zone, part of the larger Sunda subduction zone, at a speed of 45 mm/yr. The angle between the direction these two plates move relative to each other is not always at a right angle (90°) to the subduction zone itself--here it is about 50°. Sliding under the Sunda Plate at an angle is not easy, so several large strike-slip fault systems help to accommodate some of this movement. If you thought learning vectors in high school was pointless—think again. This is a perfect vector component problem!
