| Abstract (English): |
Although earthquakes have been scientifically studied for more than a century, essential questions as the possibility of predicting catastrophic events remain still open. Here we introduce an original experimental setup that mimics the behavior of a tectonic fault. By continuously shearing a granular layer under confined pressure, we are able to obtain a dynamics ruled by scale-invariant avalanches. We monitor the sizes of these avalanches by two methods and both show a power-law distribution (similar to the Gutenberg-Richter law). There is also a strong resemblance between waiting times distribution in our experiment and other studies with real earthquakes data. [ABSTRACT FROM AUTHOR] |

Aunque los terremotos han sido estudiados científicamente durante más de un siglo, preguntas esenciales como la posibilidad de predecir eventos catastróficos permanecen todavía por resolver. Aquí introducimos un sistema experimental original que imita el comportamiento de una falla tectónica. Mediante el cizalle continuo de una capa granular sometida a una presión de confinamiento, somos capaces de obtener una dinámica de avalanchas invariantes de escala. Supervisamos los tamaños de estas avalanchas por dos métodos y ambos muestran una distribución en ley de potencia (similar a la ley de Gutenberg-Richter). Hay también una gran similitud entre la distribución de tiempos que espera entre eventos obtenidos en nuestro experimento y otros estudios con datos de terremotos reales. [ABSTRACT FROM AUTHOR] |
