# Applied Engineering Using Schumann Resonance for Earthquakes Monitoring
## 4 Conclusions  
This paper shows the existing ELF stations and their experimental range of coverage, for the detection of seismic events. On the other hand, the earthquakes with related tsunamis that occurred throughout history were located. When considering the relationship between the detection of precursory electromagnetic phenomena and seismic events, this work highlights the lack of coverage for almost the entire southern hemisphere, warning the community about the seismic risk for the area of South America and South Asia for their high seismic activity. The location of ELF observatories is proposed to provide a minimum coverage of seismic risk alert worldwide, although this methodology is largely experimental and widely studied today.  
The ELF stations proposed in this paper are set in the areas of the greatest potential risk in the development of high magnitude seismic events or damage to populated areas, depending on the experimental distances for detecting this kind of phenomena (500 km and 1000 km). The proposed increase in the number of stations allows for greater potential comparative study and better behavior of these events. With this procedure, it should have carried out a greater number of works and the distribution scope is similar to the ones from other natural damage such as landslides, forest fires, and earthquakes studies to confirm and continue with the work that reinforces the use of these observing systems as a tool for early detection of seismic events of interest. So, the goal is to avoid possible global catastrophes with the related study of ELF signals of the observatories.  
Despite that the relation between the detection of these seismic events and the ELF signals measurements (highlighting the Schumann resonance signal) is not totally verified; many studies are being contributed into investigation in the last few years. Works that showed anomalies or variations in these ELF signals a few weeks or days before the occurrence of large seismic events occur. These investigations are of interest due the major implications that can soon be developed through them soon. Therefore, this work opens new perspectives in the early detection of earthquakes and tsunamis in the world.
