Greece Earthquake Tectonic Plates What Is Earthquake Causes And Effects

The earliest documented earthquake occurred in china in 1177 bc.

Turkey news last minute greece earthquake tracker. This has long been apparent from early catalogs of felt earthquakes and is even more readily discernible in modern seismicity maps which show instrumentally determined epicentres. In other places where plates are moving towards each other one plate is forced underneath another plate. While this causes earthquakes and other seismic activity interactions between the eurasian and african plates cause a much more fascinating phenomenon.

Tectonic plates tuck together and move yielding tension. The most important earthquake belt is the circum pacific belt which. Earths crust is made of several tectonic plates which slowly move around earths surface.

But for most of history people didnt really have any idea what caused them though they had some wild theories such as the belief earthquakes were caused by air rushing out of caverns deep in the earths interior. The movement of tectonic plates causes earthquakes when two plates that are in contact with each other move in opposite directions and release built up stress. An earthquake is analogous to a game of tug of war.

These earthquakes are not random. In california there are two plates the pacific plate and the. Rather they are the effect of different changes occurring in the earths crust for a long time.

The nature of earthquakes causes of earthquakes. An earthquake is basically a rapid movement of the ground usually back and forth and up and down in a wave motion. For example one plate may move north while the other may move south.

When the force is great enough the plates suddenly move as friction can no longer hold them. Earthquakes can be human made or natural although the latter is more abundant. Earthquake in oceans is known as tsunami which is equally devastating.

At this region most interactions between the tectonic plates occur and hence cause more earthquakes. The aegean sea plate is currently moving at approximately 30mm in a southwestern motion against the eurasia plate and this action causes seismic activity in both northern and central greece. Friction between the plates must be overcome before they move.

It is caused by the rapid release of energy as the tectonic plates move. Earths major earthquakes occur mainly in belts coinciding with the margins of tectonic plates. The main causes of earthquakes fall into five categories.

An earthquake is caused by a sudden slip on a faultthe tectonic plates are always slowly moving but they get stuck at their edges due to friction. The results are known as subduction zones and the worlds largest earthquakes occur in these regions. Stress can build up to a significant amount while the plates are held stationary but trying to move which can.
