Meanwhile, DOST-Phivolcs Director Renato Solidum that yesterday’s earthquake was quite different from the 1990 earthquake in Northern Luzon though they had same magnitude.

“The 1990 earthquake was caused by a horizontal fault,” explained Dr. Solidum. “However, the Negros-Cebu quake was cause by a thrust fault, which is similar to two cars colliding, and the hood of one car is on top of the other.”

Since the 6.9 magnitude earthquake at 11:49 AM on Monday, DOST-Phivolcs has recorded more than a thousand aftershocks, most of which were not felt. (Framelia V. Anonas)
