Listen - Read & Understand - How Earthquakes Happen - Ex 928
Earthquakes are one of the most powerful natural events in the world. Tectonic plates produce them by moving and suddenly slipping along faults in the Earth's crust. A single earthquake can release energy equivalent to thousands of atomic bombs in a matter of seconds.
Earthquakes never go unnoticed by scientists. Seismologists have found evidence of earthquakes more than three thousand years old in geological records, and they were still able to analyze their power! This is possible because tectonic plates are always moving and storing energy until it is released.
There are more than three hundred active fault lines in the world. Their strength and effects change depending on the type of plate movement. Shallow earthquakes generally cause more destruction than deep earthquakes. Today, earthquakes are studied in science, monitored with advanced technology, and prepared for with emergency plans all around the world.
Los terremotos son uno de los eventos naturales más poderosos del mundo. Las placas tectónicas los producen moviéndose y deslizándose repentinamente a lo largo de fallas en la corteza terrestre. Un solo terremoto puede liberar energía equivalente a miles de bombas atómicas en cuestión de segundos.
Los terremotos nunca pasan desapercibidos para los científicos. Los sismólogos han encontrado evidencia de terremotos de más de tres mil años en registros geológicos, ¡y todavía pudieron analizar su poder! Esto es posible porque las placas tectónicas siempre se están moviendo y almacenando energía hasta que se libera.
Existen más de trescientas fallas activas en el mundo. Su fuerza y efectos cambian según el tipo de movimiento de las placas. Los terremotos superficiales generalmente causan más destrucción que los terremotos profundos. Hoy en día, los terremotos se estudian en la ciencia, se monitorean con tecnología avanzada y se preparan con planes de emergencia en todo el mundo.
