Deadliest Earthquakes - Essay Example

 A megathrust earthquake is an earthquake that occurs as a result of two locked plates experiencing accumulated stress. Scientific evidence suggests that these earthquakes can occur within the contact zones between North American and Juan de Fuca plates because they are locking together and accumulating strain. 4. Silent or slow-moving earthquakes are those that take place over a long period, weeks or months, and they can importantly predict huge and more destructive earthquakes. The silent earthquakes trigger the assessment of stress builds up along zones of fault thereby increasing the chances of earthquake prediction. 5. Shake alerts are warnings given to people before rapid ground shaking associated with earthquakes arises.

Seismologists do this by detecting the initial energy that radiates from the earthquake known as the P-Wave, which does not usually cause damage. Information from P-waves then estimates the magnitude and location of earthquakes. They then anticipate the level of ground shaking across an area that will be impacted and offer a warning to residents. Warnings are given before S-waves arrive, which involve strong ground shaking that may lead to widespread damage. Comments on the video for posting on the blackboardDeadliest Earthquakes is yet another insightful video on the tireless efforts of geologists to find ways to predict natural disasters.

Advancements in seismology are presented, and their capabilities are shown in the video. Further, concerns from other members of the society regarding identifying ways to successfully predict earthquakes are presented. This is seen in the “Holy Grail of Seismology.” I think that the video is a great educational tool, which not only offers great insight into the ways that geologists measure and predict natural disasters but also educates viewers on the various characteristics different types of earthquakes.

Can Animals Predict Disaster?1. Animals can be able to predict disasters. There have been numerous accounts where animals flee from disasters long before they occur. These events have baffled both residents where disasters have occurred and scientists. Assessments of destruction sites have shown that animals are able to predict disasters as carcasses of animals are usually absent. Scientists now state that some animals have the ability to hear “infrasound,” which emanates from natural phenomena such as storms, volcanoes, and earthquakes. 2. There is sufficient evidence to ascertain the fact that animals can be able to predict disasters.

The Indian Ocean disaster popularly known as the Tsunami, which contributed to the demise of more than one quarter, illuminated amazing accounts of survival among the animal kingdoms. Srilankan dogs refused to go to customary walks, buffalos in Thailand went in a stampede up a hill saving villagers who followed them are all proof that animals can predict disasters.
