The Wednesday Centerfault (5)

After we dealt with some faults in Greece, let’s move to Spain. The Ventas de Zafarraya Fault (VZF) west of the Granada basin (36.96° N, 4.14°W) has a beautiful morphologic expression and an exciting history. The fault bounds the Zafarraya polje to the south, with Quaternary sediments to the north (hanging wall) and limestones of the Internal Subbetics in the footwall.

New paper on the paleoseismicity of the Dead Sea – Kagan et al., 2011

Some days ago a new paper on the paleoseismicity of the Dead Sea area during the late Holocene has been published in JGR. Kagan et al, 2011 investigated two new study sites in the northern and southern parts of the Dead Sea Basin and compared the seismites found there with the information of the Ein Gedi core presented by Migowski et al., 2004.

The Wednesday Centerfault (1)

It’s not easy to prepare weekly Friday links when you are abroad, this is what I had to realize in April. However, I will try to post a natural beauty each Wednesday in the future, the Wednesday Centerfaults and Centerfolds.

Today, I start with the Kaparelli Fault in Greece (38.22°N, 23.23°E). This beautiful limestone fault scarp is more than 2.5 km long and up to 5 m high. The fault was activated during the 1981 Corinth earthquakes. Continue reading “The Wednesday Centerfault (1)”

New paper: Alsop & Marco: Soft-Sediment deformation within seismogenic slumps of the Dead Sea Basin

Some days ago, a great new paper was published on the investigation of soft-sediment deformation in paleoseismology: “Alsop & Marco 2011: Soft-Sediment deformation within seismogenic slumps of the Dead Sea Basin. Journal of Structural Geology 33 (2011) 433-457.” The authors investigated the most beautiful seismites I’ve ever seen and generated different scenarios for their interpretation with respect to paleoseismic events.

What’s up? The Friday links (4)

The California Geological Survey provides a great online-tool for geoscientist: A fault map of California (Alquist-Priolo-Fault-Zone with all datasets available in PDF and GIS format for free! Start here.

A volunteer panel that assesses earthquake risks in Utah said it examined nearly 130 school buildings in the state and found more than half fail to meet federal earthquake safety guidelines. Bad news from here.
