Earthquake Warning Technologies Applied in Turkey and Japan, 25th September 2014

About Seminar

Our purpose in organizing this event is to increase our awareness about earthquake warning technology. In view of this, we aim to obtain information about the application of these systems in our country and Japan. Japan experiences frequent earthquakes and is considered the world leader for technology related to this topic.

More than 30 percent of our country’s population lives in the Marmara region, accounting for nine percent of the area of the country and approximately 40 percent of the gross national production of the country. In 1999, an earthquake occurred in Izmit, Kocaeli in the Marmara region, damaging the country’s economic infrastructure and causing 6 million dollars in damage and nearly 20,000 casualties.

Similarly, the 1995 earthquake in Kobe in Japan caused 6,500 casualties and economic losses of 150 million dollars (2.5% of the gross national product) and is recorded in history as the most expensive earthquake. As with the Marmara region earthquake, the vast expenses resulted mainly from the intensive industrial area in and around the city of Kobe.

In particular, the massive 150 million dollar economic loss of the Kobe earthquake shows the requirement of earthquake warning systems for heavily populated areas and industrial facilities. The majority of the damage was not directly caused by the 20 second earthquake but caused by the earthquake triggering gas leakage, electric ignition, explosions, fire, human panic in high-rise buildings, and a number of other incidences based on secondary disasters. In Japan, many risk reduction strategies exist however these approaches are understood to be insufficient and the development of earthquake warning technology is essential.

In order to reduce the loss of life and protect our economic investments during an earthquake, it is essential to continue the development of new technology to create early-warning networks and stand-alone warning systems.

Speech Summaries

In his opening speech of the conference, President of Fuji Engineering, Yusuf Zahit Gündoğdu, who organized this event along with Japan, discussed the purpose of this conference as to provide people and institutions with information about earthquake warning systems implementation in Turkey. Gündoğdu, having experienced the 1999 Izmit earthquake in Kocaeli, mentioned the casualties caused by the earthquake. Yusuf Zahit Gündoğdu discussed the potential for reduction of casualties and economic loss during an earthquake in areas containing high population and many industrial plants by drawing attention to the necessity for an earthquake warning system, saying “In order to reduce the loss of life and protect our economic investments during an earthquake, it is essential to continue the development of new technology to create early-warning networks and stand-alone warning systems”.
    
For the closing remarks, President of Fuji Engineering, Yusuf Zahit Gündoğdu once again came to the podium to draw attention to the effects of secondary disasters caused by earthquakes and conveyed proper measures can be taken with the implementation of real-time alerts. Gündoğdu underlines that people may not be able to take immediate action, saying “During an earthquake, taking control or command is hard to do and may even be impossible. Therefore, in the moment of an earthquake, immediate intervention and action is vital to the prevention of secondary disasters after the earthquake”. Gündoğdu states that “With real-time warning systems, critical functions are stopped and it is possible to prevent secondary disasters”.
Dr. S. Ümit Dikmen, Associate Professor of the Department of Earthquake Engineering at Kandilli Observatory and Earthquake Research Institute, gave a presentation entitled “Istanbul Earthquake Early Warning and Rapid Information Systems”. Dikmen underlined that the placement of 100 sensitive earthquake sensors in Istanbul, as is thought with earthquake early warning systems, gives prior notice of an earthquake and provides an early exit from the building. Dikmen also noted that during an earthquake, early warning systems aim to prevent greater dangers by stopping electrical, natural gas and similar disasters.

Dikmen described the Istanbul Seismic Risk Mitigation and Emergency Preparedness Capacity Enhancement Project (ISMEP). As a priority, the seismic risk conditions of significant public buildings are to be examined and according to the examination, the buildings will be strengthened or demolished and rebuilt. With this system, Dikmen emphasized that the damage of a building can be predicted and he iterated which building and how it will need early intervention is known. The seismic movements of high-rise buildings and industrial plants can be controlled by placing recording devices, states Dikmen, and the records taken from the devices after an earthquake detail the necessary interventions.

Cultural history buildings are also subject to this monitoring, including Hagia Sophia, Suleiman Mosque, Fatih Mosque, Mihrimah Sultan Mosque and the Blue Mosque, noted Dikmen. He also mentioned the third Bosphorus Bridge under construction along with the two existing bridges will also be earthquake monitored.

Dikmen also expressed that the Marmaray will be monitored, with recording devices placed at the beginning and end of each tube underwater.
Turkey Earthquake Foundation, Chairman of the Board Prof. Dr. Hasan Boduroğlu gave a presentation called “Earthquakes and Awareness”. Boduroğlu touched on this topic, saying it is necessary to be conscious of the risks and effects of an expected major earthquake in an area. Boduroğlu said “Above all else, are we aware of this risk? The risk could relate to our homes and our workplaces. Additionally, schools, hospitals and similar buildings that we use may be at risk”.

Indicating that even an earthquake resistant building has the potential to collapse, Boduroğlu drew attention to non-structural hazards. He stated “We aren’t actually ‘aware’ of the danger we are in”; the death and injury of “buildings” first comes to mind. When a building collapses, the source of danger arises from the objects within the building, explained Boduroğlu, emphasizing the importance of determining possible risks and making necessary preparations. Before an earthquake, information about what to do during and after an earthquake should be provided; “Don’t be afraid of earthquakes, learn about them” Boduroğlu expressed to the audience.
Bogazici University Kandilli Observatory and Earthquake Research Institute’s Prof. Dr. Ali Pınar shared information in his presentation about the Marmara Region Earthquake Warning System conducted at the Kandilli Observatory and Earthquake Research Center. When comparing regional and onsite earthquake warning systems, Pınar indicated that in areas close to the earthquake zone, the onsite system should be preferred and in more remote locations, the regional system should be preferred.
 
Pınar gave information about the seismic network used in the Kandilli Observatory onsite earthquake warning studies and later mentioned the observatory’s regional earthquake early warning algorithms VIRTUAL Seismologist (VS), Presto and ElarmS.

Prof. Dr. Ali Pınar pointed out that in general, earthquake early warning systems consider short and rigid structures. The majority of seismic energy is carried through long period waves, therefore even earthquakes occurring far away still put high-rise buildings at risk, Pınar underlined. Every year, the number of long period and high-rise buildings in Istanbul is increasing; “Therefore, it is especially important to work on regional earthquake warning systems to reduce the impact of earthquakes occurring from a distance” emphasized Pınar.
Dr. Fatih Sütçü, of Istanbul Technical University, Earthquake Engineering and Disaster Management Institute, gave a speech entitled “Japanese Meteorological Agency Disaster Warning System / Japanese Earthquake Early Warning System Observations”. Dr. Fatih Sütçü completed his doctoral studies at Tohoku University between the years 2003 and 2006, and later transferred to Tokyo Institute of Technology to conduct his post-doctoral work in strengthening structures following the disastrous Fukushima earthquake on March 11, 2011. According to Sütçü’s findings after transferring, both Tohoku University and Tokyo Institute of Technology use buckling restrained braces (BRB) at the façades as strengthening when designing isolated buildings.

Dr. Fatih Sütçü continued his presentation, giving information about earthquakes and early warning systems of the Japanese Meteorological Agency. Earthquake signals are collected for the Early Warning System by the Japanese Meteorological Agency and then processed in four second lengths through algorithms to determine if the signals are earthquake waves. This information is transferred to the Early Warning System and is then alerted to concerned individuals and entities, explained Sütçü. The early warning consists of two measures: the first priority warning report is intended for schools, hospitals, factories, etc., and the second emergency earthquake alert is made known for the public.
IMV Corporation Japan, Thermal and Nuclear Plant System Reinforcement Measuring Instrument Expert, Kenji Akiyoshi presented about the tripartite Japanese earthquake strategy. No one can predict the size of an earthquake; the great disaster caused by the 1995 Kobe Earthquake spurred the renewal of seismic retrofit strategies in Japan, Akiyoshi noted. He mentioned the adoption of the approach to lower losses during and after the earthquake. The three-way system consisting of early warning systems, seismic monitoring networks and earthquake measuring devices all working together, indicated Akiyoshi, can compensate for any disruption that can be experienced, as should an ideal system perform. Akiyoshi underlined the importance of early warning systems to ensure the size of disasters do not increase, especially for industrial buildings, water storage areas such as dams, and power plants. In this sense, he emphasized the vital importance of earthquake observation devices.
