Earthquakes do not occur randomly throughout the Earth, but they occur in distinct zones, which could be linked to the edges of tectonic plates located on the surface of Earth. Figure 6 illustrates the geographical distribution of regions with seismic activity that are most common. The boundaries of active plates are superimposed on the map.
The earthquakes are mostly scattered along the edges the platonic plates that are visible on the map.
- The lines colored in red indicate the boundaries of plates, which could extend overtake one another, causing an earthquake.
- The map also distinguishes various movement of the plates such as pressing against one another or separating.
- This map also points out eruption of volcanoes in oceans, which trigger earthquakes on earth.
Where are the earthquake distribution centers in the area?
The majority of earthquakes occur in extremely small areas along oceanic ridges or transform faults along faults that transcurrent across the continent as well as in more extensive areas beneath as well behind islands arcs. The depth distribution of the earthquake is also quite limited. Most of the energy released by the earthquake is formed in the crust.
Does earthquake happen everywhere?
Every day, earthquakes occur all around the world and occur along both plates’ edges and insides. Earthquakes are triggered by faults that are cracks between blocks of rock, which allow them to shift in relation to one another.
Tectonic Earthquake
A tectonic earthquake happens when a plate shifts and releases a huge amount of energy which moves in all directions away from the epicenter. This causes the surface to shake.
What is the distribution of volcanoes on a the map?
Volcanoes do not appear to be accidentally scattered across the earth’s surface. Mostly in the coastal areas of the continent, along the chains of the island or under the sea, creating long mountains. The major plates of tectonics of the Earth.
How do earthquakes are distributed on an image?
Earthquakes occur along fault lines, meaning that they occur they occur at the edges of plates of tectonics. Looking at the plate tectonics map, the quake spreads along the lines shown on the map. The most frequent locations for earthquakes are in the areas where the massive plates that comprise the crust of Earth meet and rub.
