Using Dust and Pollen to sleuth the origin of lacustrine seismites

For quite some time (~7 years), I have been noticing that Holocene Dead Sea seismites frequently have a thin dark flat lying fine grained  layer of sediment on top. When I finally gained access to some electron microscopes at Cambridge University in 2013, I saw that these thin layers were very fine grained. After consultation with Dust Geologist Dr. Ken Pye, I came to the conclusion that they appeared to be proximal dust deposits. It was around that time that I realized that Dead Sea earthquakes probably kicked up dust clouds that then settled atop the seismite. An example of a dust cloud kicked up by an earthquake in Mexico is featured in my crowd funding pitch video (Jerusalem Quake Seasonality on Kickstarter ) and can be seen here (Mountain front dust clouds – Mexicali Quake of 2010 ). Christoph Gruetzner, who is also intrigued by the link between seismicity and dust, has accumulated a number of videos showing “dustquakes” on his YouTube channel[1].

The Great Wenchuan Earthquake eight years on: earthquake damage and coseismic landslides

Last October I was given the chance to attend the “iRALL school on field data collection, monitoring, and modeling of large landslides” in Chengdu, China. During the school, we spent one week in the epicentral area of the Ms=8.0 2008 Wenchuan earthquake, where I was able to take some interesting pictures of earthquake damage and coseismic landslides. Then other things happened, like the earthquakes in Italy and New Zealand, with exciting sights from the field shared here, and I never ended up sharing my Wenchuan pics, which I want to do now.

Call for contributions to textbook ‘Structural Geology and Tectonics: Problems and Solutions’

Our colleague Åke Fagereng from Cardiff University will edit a textbook on problems in structural geology and tectonics together with Soumyajit Mukherjee and Andrea Billi. The editors invite contributions from the tectonics community. Perhaps you have a nice active tectonics exercise to share? Here is the announcement: Continue reading “Call for contributions to textbook ‘Structural Geology and Tectonics: Problems and Solutions’”

Call for papers: TECTONICS Spec. Iss. “The 2016 Central Italy Seismic Sequence: Insights, implications and lessons learned”

Our colleague Lucilla Benedetti (CEREGE, France) distributed the following call for papers on the recent earthquake series in Central Italy:

Dear Colleagues,
