How far could we get without the engineers?

So who starts analyzing the core first?

Life at Sea vs. Life in Bremen

Today was the last day of core description for Chicxulub Impact Crater scientists who have been working at the University of Bremen in Germany. You would assume that doing scientific work on land for four weeks would be a lot different than doing scientific work on the JR for eight weeks, but, surprisingly, the life you end up leading in both situations has a lot in common.

Not So Fast! Types of earthquakes at the Sumatra Seismogenic Zone

Several different types of earthquakes and fault-slip events happen at the Sunda subduction zone and other subduction zones around the world. Typical earthquakes usually last a few seconds to a few minutes, if they have very large magnitude. But not all fault slip results in typical earthquakes.

Core description on land vs. core description at sea

The Chicxulub K-Pg Impact Crater expedition 364 scientists are in Bremen, Germany right now. They are describing the cores they drilled last spring in the Chicxulub Crater.

The Sunda/Sumatra subduction zone- how does it compare to other subduction zones around the world?

Incoming! Oblique Subduction at the Sunda Subduction Zone

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!
