The event was shallow and produced strong ground shaking in the region.<\/p>\n<p><a href=\"https:\/\/earthquake.usgs.gov\/earthquakes\/eventpage\/us60007ewc\/executive\" rel=\"noopener noreferrer\" target=\"_blank\">https:\/\/earthquake.usgs.gov\/earthquakes\/eventpage\/us60007ewc\/executive<\/a><\/p>\n<p>As I write this, there have been about 5 building collapses and 22 deaths. The high number of deaths may be due to the building design used in the region.<\/p>\n<p>The EAF accommodates the relative plate motion between the Anatolia and Arabia plates. Because the northern motion of the Arabia plate is oblique to the plate boundary, the tectonic strain (deformation of the Earth) is proportioned on different fault types. We call this <a href=\"https:\/\/en.wikipedia.org\/wiki\/Strain_partitioning\" rel=\"noopener noreferrer\" target=\"_blank\">strain partitioning<\/a>.<\/p>\n<p>The lateral strain is localized along the EAF in the form of strike-slip faults. The compressive strain formed the Southeast Anatolia fault zone, a series of imbricate thrust faults south and east of the EAF.<\/p>\n<p>Further to the west, this north-south compression results in the subduction of the Africa plate northwards beneath the Anatolia and Eurasia plates. This subduction forms the Hellenic trench.<\/p>\n<p>On the northern part of Turkey is bordered by a right-lateral strike-slip fault, the North Anatolia fault. Last year (2019) was the 20 year commemoration of the 1999 Izmit M 7.6 earthquake.<\/p>\n<p>The M 6.7 earthquake may have caused landslides or liquefaction in places, but the chances of this are modest at best.<\/p>\n<p>Geologists have studied the EAF and subdivided the fault into segments based on their mapping efforts. This M 6.7 is within the P\u00fct\u00fcrge segment of the EAF. If we look at the historic record of the EAF here, we find that the M 6.7 happened in a part of the fault that does not have an historic rupture. There was an earthquake in 1875 that appears to end to the north of the M 6.7 and there is an earthquake in 1893 that appears to terminate just to the south of the M 6.7.<\/p>\n<h2><font color=\"orange\">Below is my interpretive poster for this earthquake<\/font><\/h2>\n<ul>\n<li>I plot the seismicity from the past year, with diameter representing magnitude (see legend).

These authors used a global dataset of earthquakes to develop an empirical relation between earthquakes and various parameters. They found relations between the physical size of an earthquake versus earthquake magnitude. These plots show how the magnitude of an earthquake relates to the &#8220;surface rupture length in km.&#8221; The surface rupture length is the length of the fault that actually caused the ground surface to be offset during the earthquake.<\/li>\n<li>The table shows calculated magnitudes based on surface rupture lengths of different length. Given the formula in the Wells and Coppersmith (1994) plot shown, an earthquake with a surface rupture length of 35 km would have a magnitude of M 6.8. Note how the aftershock zone is about 75 km long. We will see in the coming week or two if there is a potential for finding surface rupture. Geologists will use satellite data to measure ground offset. This type of remote sensing analysis can help people locate field observations of surface rupture. This kind of analysis was very helpful for our mapping following the <a href=\"http:\/\/earthjay.com\/?p=8706\" rel=\"noopener noreferrer\" target=\"_blank\">July 2019 Ridgecrest Earthquake Sequence<\/a>.<\/li>\n<p><a href=\"http:\/\/earthjay.com\/earthquakes\/20200124_turkey\/20200124_turkey_interpretation_aftershocks.pdf\" rel=\"noopener noreferrer\" target=\"_blank\"><br \/>\n<img decoding=\"async\" src=\"http:\/\/earthjay.com\/earthquakes\/20200124_turkey\/20200124_turkey_interpretation_aftershocks.jpg\" width=\"100%\" alt=\"\" \/><\/a><\/p>\n<li>Let&#8217;s take a look at the USGS fault slip model.

Maximum slip is less than 2 meters.<\/li>\n<li>Note the coincidence between the estimated length of surface rupture length in the table above (35 km) and this slip model. The slip model shows slip on the fault at or near the surface for about 40 km or so.<\/li>\n<p><a href=\"http:\/\/earthjay.com\/earthquakes\/20200124_turkey\/20200124_turkey_67_slip.png\" rel=\"noopener noreferrer\" target=\"_blank\"><br \/>\n<img decoding=\"async\" src=\"http:\/\/earthjay.com\/earthquakes\/20200124_turkey\/20200124_turkey_67_slip.png\" width=\"100%\" alt=\"\" \/><\/a><\/p>\n<\/ul>\n<ul>\n<li>Because this 1999 earthquake is important for many reasons, I will be writing up an Earthquake Report for that event sometime soon.

The map was created by collating maps computed using national and regional probabilistic seismic hazard models developed by various institutions and projects, and by GEM Foundation scientists. The OpenQuake engine, an open-source seismic hazard and risk calculation software developed principally by the GEM Foundation, was used to calculate the hazard values. A smoothing methodology was applied to homogenise hazard values along the model borders. The map is based on a database of hazard models described using the OpenQuake engine data format (NRML). Due to possible model limitations, regions portrayed with low hazard may still experience potentially damaging earthquakes. <\/li>\n<li>Here is a view of the GEM seismic hazard map for Europe.<\/li>\n<p><a href=\"http:\/\/earthjay.com\/earthquakes\/20200124_turkey\/GEM_seismic_hazard_europe_w_legend.pdf\" rel=\"noopener noreferrer\" target=\"_blank\"><br \/>\n<img decoding=\"async\" src=\"http:\/\/earthjay.com\/earthquakes\/20200124_turkey\/GEM_seismic_hazard_europe_w_legend.jpg\" width=\"100%\" alt=\"\" \/><\/a>\n<\/ul>\n<ul>\n<h2>\n<li>The USGS Seismic Hazard Map:<\/li>\n<\/h2>\n<li>Here is a map that displays an estimate of seismic hazard for the region (Jenkins et al., 2010).

The normalised metric allows a direct comparison of the risk between countries with widely different construction costs. It does not consider the effects of tsunamis, liquefaction, landslides, and fires following earthquakes. The loss estimates are from direct physical damage to buildings due to shaking, and thus damage to infrastructure or indirect losses due to business interruption are not included. The average annual losses are presented on a hexagonal grid, with a spacing of 0.30 x 0.34 decimal degrees (approximately 1,000 km<sup>2<\/sup> at the equator). The average annual losses were computed using the event-based calculator of the OpenQuake engine, an open-source software for seismic hazard and risk analysis developed by the GEM Foundation. The seismic hazard, exposure and vulnerability models employed in these calculations were provided by national institutions, or developed within the scope of regional programs or bilateral collaborations. <\/li>\n<\/ul>\n<li>Here is a view of the GEM seismic risk map for Europe.<\/li>\n<p><a href=\"http:\/\/earthjay.com\/earthquakes\/20200124_turkey\/GEM_seismic_risk_europe_w_legend.pdf\" rel=\"noopener noreferrer\" target=\"_blank\"><br \/>\n<img decoding=\"async\" src=\"http:\/\/earthjay.com\/earthquakes\/20200124_turkey\/GEM_seismic_risk_europe_w_legend.jpg\" width=\"100%\" alt=\"\" \/><\/a>\n<\/ul>\n<\/ul>\n<ul>\n<h2> <strong><font color=orange>Europe Earthquake Reports<\/font><\/strong><\/h2>\n<h3>General Overview<\/h3>\n<h3>Earthquake Reports<\/h3>\n<li>2020.01.24 <a href=\"http:\/\/earthjay.com\/?p=9288\">M 6.7 Turkey<\/a><\/li>\n<li>2019.11.26 <a href=\"http:\/\/earthjay.com\/?p=9130\">M 6.4 Albania<\/a><\/li>\n<li>2018.10.25 <a href=\"http:\/\/earthjay.com\/?p=7916\">M 6.8 Greece<\/a><\/li>\n<li>2017.07.20 <a href=\"http:\/\/earthjay.com\/?p=5646\">M 6.7 Turkey<\/a><\/li>\n<li>2017.06.12 <a href=\"http:\/\/earthjay.com\/?p=5535\">M 6.3 Turkey\/Greece<\/a><\/li>\n<li>2016.10.30 <a href=\"http:\/\/earthjay.com\/?p=4416\">M 6.6 Italy<\/a><\/li>\n<li>2016.10.30 <a href=\"http:\/\/earthjay.com\/?p=4427\">M 6.6 Italy Update #1<\/a><\/li>\n<li>2016.10.28 <a href=\"http:\/\/earthjay.com\/?p=4400\">M 5.8 Tyrrhenian Sea<\/a><\/li>\n<li>2016.10.26 <a href=\"http:\/\/earthjay.com\/?p=4395\">M 6.1 Italy<\/a><\/li>\n<li>2016.10.16 <a href=\"http:\/\/earthjay.com\/?p=4355\">M 5.3 Greece\/Albania<\/a><\/li>\n<li>2016.08.23 <a href=\"http:\/\/earthjay.com\/?p=4242\">M 6.2 Italy<\/a><\/li>\n<li>2016.01.24 <a href=\"http:\/\/earthjay.com\/?p=3633\">M 6.1 Mediterranean<\/a><\/li>\n<li>2015.11.17 <a href=\"http:\/\/earthjay.com\/?p=3300\">M 6.5 Greece<\/a><\/li>\n<li>2015.04.16 <a href=\"http:\/\/earthjay.com\/?p=2339\">M 6.0 Crete<\/a><\/li>\n<\/ul>\n<ul>\n<h2> <strong><font color=orange>Middle East Earthquake Reports<\/font><\/strong><\/h2>\n<h3>General Overview<\/h3>\n<h3>Earthquake Reports<\/h3>\n<li>2018.11.25 <a href=\"http:\/\/earthjay.com\/?p=7993\">M 6.3 Iran\/Iraq<\/a><\/li>\n<li>2017.12.01 <a href=\"http:\/\/earthjay.com\/?p=6733\">M 6.1 Iran<\/a><\/li>\n<li>2017.11.12 <a href=\"http:\/\/earthjay.com\/?p=6709\">M 7.3 Iraq<\/a><\/li>\n<li>2017.02.08 <a href=\"http:\/\/earthjay.com\/?p=5063\">M 6.3 Makran subduction zone (Pakistan)<\/a><\/li>\n<li>2015.10.27 <a href=\"http:\/\/earthjay.com\/?p=3079\">M 7.5 Afghanistan<\/a><\/li>\n<\/ul>\n<ul>\n<h2><strong><font color=\"orange\">Social Media<\/font><\/strong><\/h2>\n<blockquote class=\"twitter-tweet\">\n<p lang=\"en\" dir=\"ltr\"><a href=\"https:\/\/twitter.com\/hashtag\/EarthquakeReport?src=hash&amp;ref_src=twsrc%5Etfw\">#EarthquakeReport<\/a> for <a href=\"https:\/\/twitter.com\/hashtag\/depremElazig?src=hash&amp;ref_src=twsrc%5Etfw\">#depremElazig<\/a> <a href=\"https:\/\/twitter.com\/hashtag\/Deprem?src=hash&amp;ref_src=twsrc%5Etfw\">#Deprem<\/a> <a href=\"https:\/\/twitter.com\/hashtag\/Earthquake?src=hash&amp;ref_src=twsrc%5Etfw\">#Earthquake<\/a> in <a href=\"https:\/\/twitter.com\/hashtag\/Turkey?src=hash&amp;ref_src=twsrc%5Etfw\">#Turkey<\/a><\/p>\n<p>Posters here I have tweeted before, now there is a report to explain them.
