The measure of the total amount of energy released is called the magnitude of an earthquake.
Fortunately, epicenter has never been in my town and the magnitudes were less than 6 Richter
Colombia throughout its history has been hit by major earthquakes that have caused secondary hazards such as tsunamis, landslides, avalanches, volcanic eruptions, avalanches, and a catastrophic number of fatalities. It is also known that every 15 to 25 years an earthquake of over 7.8 degrees on the Richter scale and usually causes a tsunami, is presented each year plus 10 earthquakes are presented with a magnitude between 5.0 and 5.9, two between 6.0 and 6.9, one every 5 years one between 7.0 and 7.7 and one of every 15-20 years 7,8+ as explained above. The 1999 Armenia earthquake was the deadliest in the history of Colombia earthquake, it is believed that killed more than 2000 people, Colombia Earthquake of 1827 is believed to have been the most destructive and could reach a magnitude of 9, 0 and 1906 Ecuador-Colombia earthquake was the strongest during the twentieth century in Colombia which was an earthquake with its epicenter in the border of the two countries, this caused a tsunami that killed at least 1000 people
earth quake is all about a build up of strains in the earth's crest
what is an epicenter ?
La causa de los terremotos se encuentra en la liberación de energía de la corteza terrestre acumulada a consecuencia de actividades volcánicas y tectónicas, que se originan principalmente en los bordes de la placa
we faced a huge disruptive earthquake in Pakistan 2005 where the epicenter was just in between the most populated area.
Cuando hablamos de terremotos debemos tener en cuenta varios aspectos como su magnitud y el epicentro donde se origina
la magnitud se calcula con un aparato llamado sismografo, a medida que va aumentando esta se salta de escala, es decir de 10 en 10 por cada magnitud que se vaya presentando. por lo general estos terremotos se originan cerca de las placas continentales o placas tectonicas ya que cuando se produce uno se esta liberando energía (demasiada energía) debido a que se crea un punto de ruptura. cuando hay desplazamiento de lava volcánica por debajo de la superficie terrestre se pueden forman tsunamis que pueden ser catastróficos para las personas o comunidades que viven cerca de las costas.
An earthquake occurs when built up strain in a rock mass causes it to rupture suddenly. The region where the rupture occurs is called the focus.
The point on the surface directly above the focus is called the epicenter. Destructive waves propagate outward from the region of the quake, traveling throughout the earth.
Severe damage to buildings, roads, utilities etc. can occur within the epicenter.
The magnitude of an earthquake is a measure of the total amount of energy released.
The first step in determining the magnitude is to measure the propagated waves using a device called a seismograph. Based on this information, the earthquake is given a number classification on a modified Richter scale. The scale is logarithmic, so a difference of one unit means a difference of 10-fold in wave intensity, which corresponds to an energy difference of 32-fold.
Earthquakes generally occur along breaks in the rock mass known as faults, and most occur in regions near plate boundaries. Some 80% of all earthquakes occur near convergent plate boundaries, triggered by the interaction of the plates.
Earthquakes are also often associated with volcanic activity due to the movement of sub-surface magma. When an earthquake occurs under the ocean, it can trigger a destructive tidal wave known as a tsunami.
