Divergent Boundaries

Divergent boundaries occur where plates move apart, creating new cruct as magma rises. Earthquakes at these boundaries are typically shallow and moderate in magnitude, but they occur continuously alonge the global mid- ocean ridget system. On land, thee Eass African Rift System provides a visible example of continental rifting, where tensional forces produce ent shars of spareate -to- moderate.

Transform Boundaries

Transform boundaries are strike- slip zone where plates slide horizontally patt each text. The friction along these faults can lock for decades or seties, storing elastic strain that is released in sudden, destructive treamakes. The San Andreas Fault in California and thee North Anatoliain Fault in Turkey are classic examples of transform boundaries that pose high seismic risk tdensely populated ares.

It extenches from the Mediterranean Sea the Middle Eass, across the Himalayas, and into Southeast Asia and Montesisia.
