Types
of earthquakes
Earthquakes are classified according to the
depth of the focus has three types: 1 - shallow earthquakes are created at a
depth of 70 km 2 - medium and earthquakes originate at a depth of between
70-300 km 3 - and deep earthquakes originate at a depth of 300-700 km
Measuring the intensity of the earthquake
Measuring the intensity of the earthquake
Measured earthquakes usually Bmkiesin
important; The first is the "quake" Intensity, and know the severity
of the earthquake as a measure descriptive of what caused the earthquake effect
on the rights and property, and what was the standard measure of descriptive
differs from the human being for another in the description of the impact of
the earthquake according to different patterns of life in the countries of
different world, but the human factor into the intent or exaggeration there
have been many pictures of this measure, the most important measure of
"average Mercala," This measure includes 12 degrees, for example ..
Earthquake with intensity "12", it does not keep a devastating and
Weather, and cause the outbreak of the volcanoes, and fiery lava out of the
ground, and shaking the earth as a whole has a center of the solar system. The
second measure is a measure of "quake" Magnitude, has been developed
by the German "Richter" and knew his name, and depends mainly on the
amount of energy stress, which causes an earthquake, and this measure of
scientific calculated value of the seismic waves recorded by stations of
earthquakes of different, and it ..
There is little difference between the
strength of an earthquake is calculated by Helwan Observatory in Egypt or
observatory "Uppsala" Sweden.
