Earthquake And Volcano Distribution Dynamic Earth Plate Tectonics The map below shows the distribution of recent earthquakes and volcanic eruptions. from the map, you will notice volcanoes and earthquakes mainly occur in narrow bands. when compared to the map above it is clear that the majority of the world’s earthquakes and volcanic eruptions occur along plate boundaries. A large band of volcanoes and earthquakes happen around the edge of the pacific ocean, known as the pacific ring of fire. a band of volcanoes and earthquakes extend from north to south along the mid atlantic ridge. some earthquakes and volcanoes occur away from plate margins at volcanic hotspots, where the earth’s crust is particularly thin.
Earthquakes And Volcanoes Explanation Our earth is a dynamic planet, as clearly illustrated on the main map by its topography, over 1500 volcanoes, 44,000 earthquakes, and 170 impact craters. these features largely reflect the movements of earth's major tectonic plates and many smaller plates or fragments of plates (including microplates).

Figure 16.2.1 16.2. 1: distribution of volcanic activity. note the close correlation between the site of volcanic activity (in red) and lithospheric plate boundaries. click image to enlarge (source: nasa gsfc) hot spots are places where a chamber of magma has accumulated at depth beneath the surface. the volcanic islands of hawaii are a notable. Observe and analyze the locations of earthquakes and volcanoes across the globe with this interactive map that contains data layers for each phenomenon. this resource provides opportunities for students to look for patterns in the locations and prevalence of each phenomenon individually and in relation to each other.
