The Philip­pine In­sti­tute of Vol­canol­ogy and Seis­mol­ogy (Phivolcs) is­sued a tsunami alert in 20 prov­inces af­ter a mas­sive 8.3-mag­ni­tude earth­quake struck Chile Thurs­day morn­ing.

The large and shal­low earth­quake oc­curred near the coast of Chile at around 6:55 a.m. Thurs­day.

Phivolcs said an earth­quake of this size has the po­ten­tial to gen­er­ate a de­struc­tive tsunami that can strike coast­lines in the re­gion near the epi­cen­ter within min­utes to hours.

Most de­struc­tive tsunamis are gen­er­ated from large, shal­low earth­quakes with an epi­cen­ter or fault line near or on the ocean floor.

Phivolcs ad­vised res­i­dents in the eastern coast of the coun­try, namely: Batanes group of is­lands, Sor­so­gon, Ca­gayan, North­ern Sa­mar, Ilo­cos Norte, Eastern Sa­mar, Is­abela, Leyte, Que­zon, South­ern Leyte, Aurora, Suri­gao del Norte, Ca­marines Norte, Suri­gao del Sur, Ca­marines Sur, Davao Ori­en­tal, Al­bay, Davao del Sur, Catan­d­u­anes, and Davao Oc­ci­den­tal to “wait and lis­ten” for up­dates.

Phivolcs Di­rec­tor Dr. Re­nato Solidum said tsunami waves at least 0.3 me­ters or less than a ruler could reach the eastern coast­line of the coun­try.

Ac­cord­ing to Phivolcs, a tsunami is a se­ries of sea waves com­monly gen­er­ated by un­der-the-sea earth­quakes and whose heights could be greater than five me­ters.

It is er­ro­neously called tidal waves and some­times mis­tak­enly as­so­ci­ated with storm surges, it added.

A pow­er­ful 8.8-mag­ni­tude earth­quake also oc­curred off the coast of Chile on Fe­bru­ary 27, 2010, which ranked as the fifth largest earth­quake ever to be recorded by a seis­mo­graph.
