Ilmuwan temukan rem tersembunyi pada patahan gempa di Pasifik

Para peneliti telah mengidentifikasi zona penghalang alami pada patahan bawah laut yang berfungsi sebagai rem untuk menghentikan gempa agar tidak membesar. Temuan ini berasal dari studi mendetail tentang patahan transform Gofar di lepas pantai Ekuador.

Patahan Gofar terletak sekitar 1.000 mil di sebelah barat Ekuador, tempat lempeng Pasifik dan Nazca bergeser satu sama lain. Patahan ini telah menghasilkan gempa berkekuatan magnitudo 6 yang hampir identik setiap lima hingga enam tahun sekali selama setidaknya 30 tahun. Para ilmuwan sudah lama dibuat bingung mengapa gempa tersebut tetap konsisten dan terbatas dalam ukurannya.

A magnitude 5.6 earthquake struck on Thursday, May 14, with its epicenter in Chocó and was felt across multiple regions of the country without causing major damage.

A new study indicates that the Cascadia subduction zone and the northern San Andreas fault may trigger earthquakes in close succession, potentially amplifying disaster risks along the U.S. West Coast. Researchers identified evidence of such synchronization in ocean floor sediment cores spanning 3,100 years. This connection could affect cities from San Francisco to Vancouver simultaneously.
