Alaska, 22 Julai – Satu gempa bumi kuat berskala 7.8 skala richter dilaporkan berlaku di persisiran Alaska pada petang tadi.
Gempa bumi yang berpusat 60 batu (98 kilometer) dari Perryville itu dikatakan berlaku pada kedalaman yang cetek iaitu sekitar 6 batu, bersamaan 10 kilometer dalam.
“Kedalaman di bawah 70 kilometer dianggap cetek,” kata ahli meteorologi CNN, Allison Chinchar.
“Ia penting kerana gempa bumi cetek sering menyebabkan banyak kerosakan berbanding gempa bumi yang lebih dalam, tanpa mengira kekuatan,” katanya.
Beberapa rakaman detik gempa turut dikongsi di media sosial.

Namun, menurut CNN, amaran tersebut ditarik balik tidak lama kemudian oleh Perkhidmatan Cuaca Kebangsaan.
Tsunami berisiko terjadi apabila gempa bumi yang berlaku mempunyai magnitud yang tinggi dan berlaku di tempat cetek. Gempa antara 7.6 hingga 7.8 skala richter berpotensi mengakibatkan tsunami yang memusnahkan.
