It was performed several hourly earthquakes distributions for different part of the world to explain, why bay-shape hourly distribution are clear for some areas, but not for others. In this sense, it was observed that earthquakes located in the intertropical zone reveal bay-shape earthquake distribution, but not defined shape is found for earthquakes outside the tropic. The answer is given based on geomagnetic flow orientation. The angle between the geomagnetic field direction and the Earth&#8217;s surface is almost parallel in the equator and orthogonal in the poles. Furthermore, considering the Laplace&#8217;s force law, the force experienced in the electrical conductor, in presence of magnetic field, is maximum when the angle between the magnetic flow direction and the electrical conductor is 90 degrees. Here, the electrical conductor is found on the global atmospheric electric circuit, where electrical current is flowing orthogonal to the Earth&#8217;s surface. The intertropical zone has angles between the geomagnetic flow vector and electric conductor more close to 90 degrees than middle latitudes and polar areas. The hourly earthquake distribution is modelled by the time-varying electrical potential in the global atmospheric electrical circuit, which is more significant in the intertropical zone. The effect of electricity on earthquakes is based on reverse piezoelectric phenomena.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[RESUMEN Se presenta una posible teoría que relaciona el campo geomagnético y los terremotos. Se realizaron varias distribuciones horarias de terremotos para diferentes partes del mundo para explicar por qué la distribución horaria en forma de bahía es clara para algunas zonas, pero no para otras. En este sentido, se observó que los terremotos ubicados en zonas intertropicales revelan una distribución horaria en forma de bahía, por el contrario esta forma de distribución no se observa para los terremotos fuera de los trópicos. La respuesta se plantea en función de la orientación del flujo magnético. El ángulo entre la dirección del campo magnético y la superficie de la Tierra es casi paralelo en el ecuador y ortogonal en los polos. Por consiguiente, considerando la ley de fuerza de Laplace, la fuerza experimentada en el conductor eléctrico, en presencia de campo magnético, es máxima cuando el ángulo entre la dirección del campo magnético y el conductor eléctrico es de 900. Aquí, el conductor eléctrico se encuentra en el circuito eléctrico atmosférico global, donde la corriente eléctrica fluye ortogonalmente a la superficie de la Tierra. Las zonas intertropicales tienen ángulos entre el vector de flujo magnético y el conductor eléctrico más cercanos a los 900 que las latitudes medias y las áreas polares. La distribución horaria de los terremotos está modelada por el potencial eléctrico con fluctuación temporal del circuito eléctrico atmosférico global, que es más significativo en las zonas intertropicales. El efecto de la electricidad sobre los terremotos se basa en el fenómeno piezoeléctrico inverso.]]></p></abstract>
