kilometers from the epicenter of an earthquake. Tables have been formulated to demonstrate the magnitude of any earthquake from any seismograph. For example‚ for a one-unit increase in magnitude‚ there is an increase of times thirty in released energy. To put that another way‚ each number on the Richter scale represents an earthquake ten times as strong as one of the next lower magnitude. Specifically‚ an earthquake of magnitude 6 is ten times as strong as an earthquake of magnitude 5. The

Two earthquakes‚ two iconic authors - Mark Twain and Jack London - witness catastrophe‚ yet the way they perceive and describe it are different. Not one soul looks on and shall distinguish it exactly the same‚ but the mood or tone in which the disasters are described would be expected to be comparable. Twain brings to the table a personal take and focuses on the “curiosities” of the earthquake. London observes the disaster from the relative distance of “the bay”‚ while describing the destruction

Most naturally occurring earthquakes are related to the tectonic nature of the Earth. Such earthquakes are called tectonic earthquakes. The Earth’s lithosphere is a patchwork of plates in slow but constant motion caused by the release to space of the heat in the Earth’s mantle and core. The heat causes the rock in the Earth to flow

He is also believed to be the force behind earthquakes‚ an odd expansion of the power of a sea god‚ but possibly due to the association between earthquakes and tsunamis in Greece. Some scholars believe he was first a god of the earth and earthquakes‚ and only later took on the role of sea god.

In general‚ the map that contained all the earthquake distributions mostly had shallow quakes spread around. Deep quakes on the map were a lot less common. I would estimate that about 85%-90% of the earthquakes were shallow quakes. There were only three earthquakes on the map that had a magnitude of 7.0 or greater. The earthquakes that appeared to have occurred along spreading zones made up about 80% of the earthquakes on the map. Earthquakes that have occurred in these areas generally have

They range from earthquake that can’t be felt to Tsunamis that kill and destroy millions of dollars of property. No matter big or small they happen and the best geologist can predict them to a certain degree yet no natural occurring disaster can be entirely predicted or stopped. People seem to look to blame something or someone for these things but we are only
