چکیده

در این پژوهش یک روش نوین موسوم به M5، برای به‌دست‌آوردن معادلات پیش‌بینی حرکات نیرومند زمین مورد‌استفاده قرار گرفت. بیشینه شتاب زمین و بیشینه سرعت زمین بااستفاده از بزرگی زمین‌لرزه، فاصلۀ منبع تا سایت، متوسط سرعت موج برشی و مکانیسم گسلش و نیز بهره‌گیری از پایگاه داده‌های گستردۀ پژوهشگاه مهندسی زمین‌لرزه (PEER) فرمول‌بندی شدند. برای اعتبارسنجی، مدل حاصل با مدل‌های شناخته‌شده مقایسه گردید. تحلیل حساسیت و آنالیز پارامتریک برای تعیین اهمیت پارامترهای مؤثر بر مدل و حساسیت آن به تغییرات پارامترها انجام شد. معادلات پیشنهادی بسیار آسان است و می‌توان آنها را با اطمینان برای اهداف پیش‌طراحی استفاده نمود.
