Rifting in iceland: new geodetic data
Science (New York, N.Y.)
|August 6, 1971
Summary
Iceland
Area of Science:
- Geophysics
- Geodesy
- Volcanology
Background:
- The eastern rift zone of Iceland is a tectonically active region.
- Understanding rift dynamics is crucial for seismic and volcanic hazard assessment.
Purpose of the Study:
- To quantify crustal deformation in Iceland's eastern rift zone.
- To investigate the relationship between tectonic activity and volcanic events.
Main Methods:
- Analysis of geodetic survey line measurements from 1967 to 1970.
- Interpretation of ground deformation data.
Main Results:
- Measurable lengthening of survey lines observed.
- Estimated rift widening of 6 to 7 centimeters.
- Deformation potentially linked to the 1970 Hekla eruption.
Conclusions:
- The eastern rift zone of Iceland experienced significant widening.
- Volcanic activity may influence rift zone dynamics and extension.

01:50Global Climate Change
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.
01:27Fractures: Bone Repair
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...

01:20Microcracking in Concrete
Microcracking in concrete refers to the tiny cracks that can form within the material even before any external load is applied. These microcracks typically occur at the interface between the coarse aggregate and the hydrated cement paste, often as a result of differential volume changes prompted by variations in stress-strain behavior, as well as thermal and moisture movement. Initially, these microcracks remain stable and do not grow substantially until the concrete is stressed to about 30...
