Question

Which statements are correct? Select one or more: 1. Continental collisions are not associated with subduction zones so these regions typically have few earthquakes. 2. The deepest earthquakes are typically found at subduction zones. 3. Earthquakes are most frequent around the edge of the Pacific Ocean. 4. The largest earthquakes are also the deepest earthquakes. 5. Shallow earthquakes are most common at oceanic ridges.

Answer 1

• 1. Continental collisions are not associated with subduction zones so these regions typically have few earthquakes.
• 2. The deepest earthquakes are typically found at subduction zones
• 3. Earthquakes are most frequent around the edge of the Pacific Ocean.
• 4. The largest earthquakes are also the deepest earthquakes.

Step-by-step explanation:

• When the two plates collide the continental collision be neither the plates can be subducted as they have high buoyancy and when such type of the collision occurs the oceanic plates become narrow and thus have less of the earthquakes occurrences taking place.

• The deep-seated earthquakes are those were the hypocenter is below a depth of about 300 km and occurs exclusively at the convergent boundaries and has a magnitude of about 8.3 were the oceanic plates descend on to the earth mantle.

• The pacific ring of fire is a string of the volcanoes and the sites of the heavy seismic activity of the earthquake activity around 90 % of the earthquakes occur here and the ring is dotted with about 75% of the volcanoes.

• Due to this of the ring of the force the earthquake is present mostly in the pacific plate zones.
