Which outcome occurs when differential stress exceeds strength in brittle rocks during subduction?

💡 Explanation

Large magnitude earthquakes occur because differential stress causes stick-slip behavior in brittle rocks during subduction, resulting in energy accumulation and abrupt release during rupture; therefore, earthquakes occur, rather than aseismic creep, which occurs under ductile conditions.
