The high seismic activity in Peru and the low quality of buildings in urban areas indicate that the population is not prepared to face a seismic event of greater magnitude on the Richter scale. Early warning systems can give a few seconds in advance to react to a seismic event; however, due to the complexity, cost, and maintenance, they are not implemented in Peruvian territory. Consequently, there is a need to use an acquisition system capable of giving an alert with some anticipation and installing them in strategic places. The objective of this research is to design an electronic system that detects an earthquake and alerts according to the vibrational intensity through the spectrum of frequencies of the propagation of the P wave in the structures of buildings with more than 3 floors. Therefore, an electronic system has been developed that mainly uses accelerometers to capture the acceleration of the upper level of a building and also a processing methodology to obtain an alert level. The results show acceptable performance for two main reasons. First, a very limited amount of memory and a processing time of less than 15 ms are used for detection. Secondly, the alert level has a correlation greater than 0.8 with the PGA of the seismic signal that occurs in the structure. This system proposes a series of future applications such as: a national earthquake monitoring network, an early warning system, a structural health system to identify possible damage, a home automation system to mitigate accidents and a system automatic electronic system that is complemented by industrial equipment to protect the process and the operator.
