Prof. Dicle University, [email protected] 1. Introduction Earthquake, regarded as a natural disaster, has affected the whole environment since the existence of life on earth and led countries and cities to be caught unprepared. Severe and more severe earthquakes can cause losses of life and property depending on the quality of structuring and land use conditions on settlement scale. With a growing world population and increasing urbanization, new research shows that populations are becoming more vulnerable to death and injury from large earthquakes in the past 50 years (Peek-Asa et.al, 2003). Variation in the number of deaths caused by earthquakes of different magnitudes can be attributed to building codes, location of victims, epicenter location, and other factors (Tanga et.al, 2017). In particular, wrong land use decisions have increased these losses. The costs caused by natural hazards are rapidly increasing in urban area, particularly in developing countries, where a number of megacities are growing ( Li et.al, 2017). Cities in the developing world are facing increased risk of disasters and the potential of economic and human losses from natural hazards is being exacerbated by the rate of unplanned urban expansion and influenced by the quality of urban management (Tarhan et.al, 2016). According to the Earthquake Result Report issued by Ministry of Public Works and Settlement (currently called as the Ministry of Environment And Urbanization) in 2004; "In Turkey where 93% of the territory and 98% of the population are affected by various earthquakes, social and economic losses caused by earthquake disaster require to take very serious measures. Because 182 disastrous earthquakes occurred and nearly 100.000 people lost their lives in Turkey between 1900 and 2003. In addition to the irreversible consequences of losses of life and property, losses of national wealth and losses of income in national product that constitute our macroeconomic losses also cause important threats for the future” (www.imo.org.tr). Therefore, in order to minimize the losses arising from earthquakes, it is very important to take various measures at every stage from country scale to urban and building scale. After Izmit Gulf and Düzce earthquakes that occurred in Marmara Region in Turkey in 1999 and caused damages in many cities, and the rules, standards, laws and regulations have been set to minimize the hazards caused by earthquake and other natural disasters and to include what to do after these disasters. In addition to legislative regulations such as Compulsory Earthquake Insurance No. 587, Decree Law on Building Inspection No. 595 ad Decree Law No. 601 which regulates competent engineering concept, various measures have been tried to be taken by different legislations such as the Regulation for Buildings to be Built in the Earthquake Regions in 2007 and the Law on Conversion of the Areas Under the Disaster Risk in 2012 in order to reduce the risk of earthquake. Yalova selected as the study area is a province with the smallest surface area of Marmara Region in Turkey and it is located in the first-degree earthquake zone. The city which experienced the earthquake in 1999 disastrously, face with the risk of future earthquake emphasized by many researchers. Yalova is bordered by the Sea of Marmara in the north. This border has led to the fact that the western coasts of the settlement have natural beaches in some places 18 Koç, C. & Kejanlı, D. T. (2018). Land Use and Risks in Yalova After the Earthquake and these areas are used as a summer resort. When it was a district of Istanbul in 1930, it became province in 1995 and started to be attractive for investors. Yalova has six districts as Çınarcık, Altınova, Çiftlikköy, Armutlu, Termal, and Central District. Being renowned for its hot springs, the city is a settlement which mainly tourism in the west, industry in the east, and agricultural sectors in the south develop. Yalova has advantages as being neighborhood with Istanbul, Kocaeli and Bursa; whereas, it has disadvantages as being in development pressure of Istanbul, the effects of industry in Istanbul and Kocaeli, and locating in interaction area for major projects and investments in the region. This situation brings economic return but affects negatively the conservation-use balance in spatial development. The city has been exposed to the increase in population and it has had an irregular development because of incorrect planning decisions. This lead to housing of unsafe areas in terms of ground conditions as well as destroying of agricultural lands, irrigation areas, coasts, and forests in Yalova, The major earthquake occurring in Marmara Region in 1999 was milestone for Yalova as was for whole region. Effects of uncontrolled development appeared with the major earthquake. As a result the earthquake, Yalova was third province where the most losses of life and property were experienced. Even though today identities such as city of industry, agriculture, and tourism are attributed to Yalova, geological, topographic, and ecological features of the city have been usually ignored in the proposal planning decisions. When planning and land use decisions of Yalova that is located in the first-degree earthquake zone and faces with earthquake risk are evaluated, it is seen that it has significant risks.The study discusses the spatial distribution of plan decisions prepared for a city that carries such a risk after the earthquake disaster. 2. Results and discussion Yalova is the province that is located in Marmara Region in Turkey and has the smallest surface with an area of 847 km2. Yalova is bordered by Marmara Sea and Istanbul in the west and north, Kocaeli in the east, and Bursa in the south (Figure 1).

Today 61.000 residences equivalence is being heated geothermally (665 MWt, including residences, thermal facilities, 565.000 m2 greenhouse heating). Moreover, with the balneological utilisation of geothermal fluids in 195 spa’s (327 MWt), the geothermal direct use capacity is 992 MWt. ORME Geothermal Inc has completed the engineering designs of nearly 300.000 residences equivalence geothermal district heating system. 170 geothermal fields (Figure 1) have been explored in Turkey. There is a single flash power plant with 20,4 MWe installed capacity. A liquid CO2 and dry ice production factory is integrated to this power plant. A binary cycle geothermal power plant with an installation capacity of 25 MWe is going to be constructed at Aydin/Germencik. The proven geothermal heat capacity according to the existing geothermal wells and natural discharges is 3132 MWt [1]. 1. INTRODUCTION There are 11 city based geothermal district heating systems in Turkey. These geothermal district heating systems have been constructed since 1987 and many development has been achieved in technical and economical aspects. The rapid development of geothermal district heating systems in Turkey is mostly depending on; - construction of suitable geothermal district heating systems according to Turkey’s conditions, - participation of the consumers to the geothermal district heating investments by about 50 % without any direct financing refund, - geothermal heating is about % 50-70 cheaper than natural gas heating.

    FIELD REPORT A POWERFUL VOICE FOR LIFESAVING ACTION February 2016 “EXCEPT GOD, WE HAVE NO ONE”: LACK OF DURABLE SOLUTIONS FOR NON-SYRIAN REFUGEES IN TURKEY Izza Leghtas and Daniel Sullivan Introduction Turkey is the world’s largest host of refugees and asylum-seekers, with the majority – 2.8 million – having fled the conflict in neighboring Syria. Another 290,000 come from other countries, including Afghanistan, Iraq, and Iran. The Turkish government has taken a number of positive steps to improve the lives of Syri- ans in Turkey, particularly in education and employment, even holding out the possibility for citizenship. Humanitarian actors are primarily focusing their efforts on the needs of the Syrians, but the protection measures available to displaced persons of other nationalities are far fewer and their living conditions are un- derreported. Turkey categorizes people who are not Syrian and who have fled from persecution in countries other than in Europe as “conditional refugees,” allowing them to stay in Turkey only temporarily, and placing heavier restrictions on them. This includes constraints on their movements and access to work and leaves them with greater uncertainty about their future. Among the “conditional refugees” are many who face par- ticular vulnerabilities and even more hardships, including LGBT people, single women and single parents, survivors of sexual or gender-based violence, religious minorities, and refugees from African countries. The asylum system in Turkey is relatively new and faces great challenges, but it must be updated to reflect current realities. It should be based on an equitable protection for refugees of all nationalities, and include specific protection measures for refugees facing particular vulnerabilities.

    DISASTER MITIGATION THROUGH GIS TECHNOLOGY – APPLICATION OF GIS TOOLS TO YALOVA, A CASE STUDY E. Alarslan1, G. Kemper², O. Altan³ 1Dr.Ebru ALARSLAN, Division Chief in the Turkish Ministry of Public Works and Settlement 2Dr.Gerhard KEMPER, CEO of GGS – Geotechnik, Geoinformatik & Service GmbH ³ Prof. Dr. Orhan ALTAN, President of the ISPRS KEY WORDS: Disaster mitigation, GIS technology and tools, earthquake risk, Yalova ABSTRACT: This paper outlines applications of GIS tools for disaster mitigation significant in urban settlements due to high urban disaster risks rather than the other areas as a result of their denser populations, constructions, and service networks. Out of various types of natural disasters, this paper focuses on earthquakes due to high seismic risk in Yalova. Yalova is located in the south-eastern coast of the Marmara Sea, a region exposed to earthquakes (Northern Anatolian Fault Zone). The Marmara region has been seismically active from 1900-2003 when 25 devastating earthquakes - including 1999 earthquakes - occurred with magnitudes ranging from 5 to 7.4. The geologic and geomorphologic features of Yalova made the settlement especially vulnerable to the tremors of the 1999 earth- quakes. It is possible to distinguish 5 groups of geological failure areas in Yalova, namely (i) areas with slope instability resulting in deep landslides, (ii) areas of deep fine alluvium and organic material likely prone to liquefaction, (iii) areas with limestone sub- formations prone to cavitations and collapse, (iv) areas with irregular weathering profiles, and (v) areas with gypsum that initiates de- formations and is hazardous to concrete foundations. With a view to the seismic features of Yalova, the application of GIS tools will be outlined in this paper and will relate to the preparation of disaster mitigation plans; the monitoring of changes in existing landuse as well as the compliance with building codes and planning standards; and the building of spatial data infrastructure that leads to sus- tainable development.

  • Frictional Strength of North Anatolian Fault in Eastern Marmara Region Ali Pınar* , Zeynep Coşkun, Aydın Mert and Doğan Kalafat
    Pınar et al. Earth, Planets and Space (2016) 68:62 DOI 10.1186/s40623-016-0435-z FULL PAPER Open Access Frictional strength of North Anatolian fault in eastern Marmara region Ali Pınar* , Zeynep Coşkun, Aydın Mert and Doğan Kalafat Abstract Frequency distribution of azimuth and plunges of P- and T-axes of focal mechanisms is compared with the orientation of maximum compressive stress axis for investigating the frictional strength of three fault segments of North Anato- lian fault (NAF) in eastern Marmara Sea, namely Princes’ Islands, Yalova–Çınarcık and Yalova–Hersek fault segments. In this frame, we retrieved 25 CMT solutions of events in Çınarcık basin and derived a local stress tensor incorporating 30 focal mechanisms determined by other researches. As for the Yalova–Çınarcık and Yalova–Hersek fault segments, we constructed the frequency distribution of P- and T-axes utilizing 111 and 68 events, respectively, to correlate the geometry of the principle stress axes and fault orientations. The analysis yields low frictional strength for the Princes’ Island fault segments and high frictional strength for Yalova–Çınarcık, Yalova–Hersek segments. The local stress ten- sor derived from the inversion of P- and T-axes of the fault plane solutions of Çınarcık basin events portrays nearly horizontal maximum compressive stress axis oriented N154E which is almost parallel to the peak of the frequency dis- tribution of the azimuth of the P-axes. The fitting of the observed and calculated frequency distributions is attained for a low frictional coefficient which is about μ 0.1. Evidences on the weakness of NAF segments in eastern Marmara Sea region are revealed by other geophysical≈ observations.

Subject classification: Armutlu Peninsula; Attenuation; Coda wave quality factor; Geothermal sources; North Anatolian Fault Zone. ABSTRACT The Armutlu Peninsula, is located in a geologically complex system on the North Anatolian Fault Zone and inside the high populated Mar- mara Region. Due to its location and importance, the Marmara Region has been subject to various studies in the past; now, this study is aimed to determine the local attenuation characteristic of the Armutlu Peninsula. In this study, 75 earthquake data that were recorded between 2013- 2014, were analyzed by 9 seismic stations. The magnitudes (Ml) and the focal depths of the earthquakes vary from 1.5 to 3.3 and 0.9 to 16.9 km, respectively. A single back-scattering model was used for calculation of the coda wave quality factor. The lapse times were determined between 20 and 40 s at intervals of 5 s and they were filtered at central frequencies of 1.5, 3, 6, 9 and 12 Hz band-pass designed filter. Min- imum 5 signal/noise ratio and 0.7 correlation coefficient data used to obtain reliable results. The CODAQ subroutine integratedin the SEISAN software was used for data processing. For each station, low values of the quality factor at 1 Hz (Qo) and high values of the frequency de- 0.91 0.72 pendent parameter (n) were determined.
