Intensity 6.8 Quake Traumatizes CES Pupils, Teachers

The building is shaking! A water inside the glass is making a wave! I couldn't stand straight! I feel dizzy! The coconut trees are terribly shaking!

CES pupils
Innocent Pupils of Cubay Elementary School
These are the traumatic reactions of the pupils and teachers of Cubay Elementary School when intensity 6.8 earthquake hits La Carlota at 11:49 a.m. before noon today.

The school principal while he was inside his office noticed that the couch while he was sitting was moving to and fro. He overheard from the outside the howls and shouts of the pupils. He rushed outside to check and realizing later that there was an earthquake.

A score of pupils covering their heads were led by their teachers to gather in an open space to settle down and wait for the quake to stop. Some proceeded directly to the nearby sugarcane field just across the gate of the school.

The school principal giving instructions
All teachers were in alert. They supervised every pupil to follow the instructions as relayed by their school principal.

While the children were waiting for their parents, guardians to fetch them home, they're carefully instructed by their school principal and reminded them in what to do just what they're doing in their earthquake drill before.

A grade 6 boy relayed his traumatic experience. He couldn't believe seeing the coconut trees in a nearby place terribly swaying to and fro where in fact there is no strong wind or typhoon.

An H.E. teacher told that she saw how the building which housed the principal office and Learning Resource Center shook for several seconds. The teacher was nervous while relating her tale to the school principal.

Another Grade 3 girl said that while having her lunch, leaning in a trunk of a tree, she was surprised to find out that the trunk was moving and finally shaking. She was shocked and afraid.

The principal has his own tale to share too. While standing on the ground just outside his office, he complained why he couldn't stand erect and he felt dizzy. His teachers shared same situations.

The schools division superintendent immediately issued unnumbered memo declaring the suspension of classes due to the earthquake until Wednesday to give time the city to inspect the building of the school whether it is safe to occupy after the earthquake.

This is the first time in the history of La Carlota where the city is hit by intensity 6.8 quake.

  1. I was at work the whole day and no one texted me about this. I just learned it when I got home and went online. Saw the photos of devastation in Negros Oriental...really sobering. It's a relief that there seems to be no damage of such scale in our province. But let's pray for everyone, especially for the people of Negros Oriental who are just recovering from typhoon Sendong. Thank God you and your family are ok.

    1. My wife keeps on praying. She was joined with her grandchildren ranging from 5, 7 and 8. As of this writing, I'm still in processing of adjusting myself. I was terribly affected upon seeing and hearing our pupils howling and shouting! They couldn't believe such strong tremor in a broad daylight.

  3. it was not felt here in metro manila but i know how it must have been for people in the Visayas. we used to live in a condo and every time an earthquake occurred, i'd pray very hard to keep my family safe. prayers do help. and moving into a 2-floor house does too. =)
