The cause of earthquakes
caused by the earthquake has two reasons:
1.1 The cause of the Tech Tonic (Tectonic Earthquake) earthquakes occur frequently, often caused by Tech Tonic. A strong tectonic stress is one of the world to push, pull, push. Or do the hard rock inside the Earth causing horizontal cracking, which has resulted in the shifting movement friction during the release of energy can cause earthquakes. If horizontal cracking is moving in regularly. And gradual There would be no more dangerous But if the line is moving abnormal rupture. Or sudden Will cause earthquakes Violence has enormous danger For the earthquake rupture in the line is called. "Origin earthquake" (Focus) by the earthquake that appear on the surface of the ground that is. "Earthquake" (Epicenter), which is dotted with violence and caused the most damage. The intensity of seismic waves It radiates from the center to all directions and gradually weaken until dissolution
earthquake epicenter =. (The earthquake)
Focus = Origin earthquake
tectonic crust =
earth's surface = earth
mantle mantle = atmospheric
shock wave seismic waves =
1.2. The cause of the explosion (Explosive Earthquake) of blast waves. The vibration of the ground. The explosion that caused the earthquake. May come from man-made, such as the atomic bomb experiments. hydrogen bomb Or may occur naturally, such as volcanic eruptions. Etc.
elements that cause harm and damage from earthquake
damage usually caused by earthquakes. There will be more or less based on several components as follows:
1. The size of the quake. Which is measured using a standard Richter (Richter) earthquake measuring 5.6 Richter common to have earthquake measuring 6-7 on the Richter scale is considered quite severe and 8-9 Richter being the most
two. The severity of the earthquake Which is measured by feelings of people and animals. Or the impact on building a severity rating. You can see from the table success The details of the impact. Successfully There are several such use Section Section Section JM MSD (Japan Meteorological Agency: JMMA Scale) Mara alumni Callies. Improved (Modified Mercalli: MM Scale) for Thailand. Section Merrill Callies
geologists have divided the magnitude earthquake compliant Richter as 12 levels of
1.0 to 1.9 Richter, a level that people generally do not feel the earthquake, more objects will be trembling. a bit like a gently undulating surface
2.0 - 2.5 on the Richter scale was felt in building earthquake. Especially on the higher floors of the building were hanging objects to swing or oscillation is
2.6 to 3.3 on the Richter scale was felt in building earthquake clearly. The quake felt like a truck passing away. The person will not feel an earthquake
from 3.4 to 4.0 on the Richter scale was located in the building will feel like a truck hit the building. The car rocked notice There was fire shutters People who sleep and wake The person will feel certain that an earthquake of
4.1 to 4.6 Richter scale, things are not stable to falling glass may crack, many people are shocked. If you sleep on it, wake The people who are most likely to feel an earthquake
from 4.7 to 5.2 Richter scale equipment such as tables, chairs, moving or falling to ruins. Everyone will feel like an earthquake. Both indoors and outdoors. Some people may panic and run out of the building,
from 5.3 to 6.0 on the Richter scale is unstable buildings could collapse. People standing will stand tough. Everyone is shocked and ran out of the building. Tree shaking Wave surface The banks may collapse Most drivers will feel the vibration clearly
from 6.1 to 6.9 on the Richter scale caused a riot. High building will be knocked down trees shake vigorously. People are shocked by
7.0 to 7.4 Richter scale structure of the various buildings are inclined from vertical. Pipes embedded definitively separate the damaged buildings
from 7.5 to 7.9 on the Richter scale is split. Landslides along river banks, construction and buildings were destroyed
8.0 to 8.4 Richter scale landslides earth is destroyed bridges. Rails bent, damaged buildings and buildings destroyed destruction
from the 8.5 Richter to buildings and buildings were destroyed almost everything to tumble out much damage
the earthquake 3. area. If an earthquake occurs near a large city communities or indeed caused much damage. However, if the remote area communities. It is less dangerous
4. During the earthquake If long-term earthquake warnings are less harmful. The people had a long time to prepare before the big earthquake. And if the earthquake happened during the day. Dangerous, it happens with people less at night. Because people may have to help themselves
5. Fire and flood If fire and flood as well. The more damage there is no
damage from the earthquake,
an earthquake with a magnitude and intensity. Inevitably cause harm and damage follows
: 1. People who live in areas where earthquakes. It caused panic, panic, panic symptoms may include nausea, vomiting, or life-threatening injuries. The building material Or buildings falling Or from fire, flooding,
2. buildings used equipment and buildings. Shake loose rock deformation Less collapses Destroyed roads The division has collapsed or collapsed fluid railway bending curve impracticable. And utilities such as electricity poles were destroyed telephone pipe.
