HOW does it feel to experience tremor while underwater?
A diver shares his experience when Magnitude 5.7 earthquake and subsequent tremors struck Batangas province last April 8.
“It felt like there was a huge propeller of a big boat turning around directly above us, we heard underwater the trembling of rocks under the ground and we felt the shock wave, it hurt our ears, feeling heavy breathing and sudden changes in pressure,” said Jan Paul Rodriguez in his account of the tremor.
Rodriguez, a Philippine Coast Guard personnel, posted a video clipping in his social media account with the caption, “How do you feel the 5.7-magnitude earthquake underwater????”dated April 8, or on the same day that the quadruple tremors hit Batangas.
The video clip shows divers in green-blue water when the ground underneath begins to rumble and move back and forth. The trembling sounds get louder as seconds pass, while the sand begins to rise up.
The U.S. Geological Survey (USGS) recorded the first earthquake as a 5.7-magnitude earthquake with its epicenter at Brgy. Bagalangit, Mabini town in Batangas province. Philippine Institute of Volcanology and Seismology (PHIVOLCS) reported it to be at Magnitude 5.6 and with an impact of Intensity 6 in Mabini town.
Just a minute after, another Magnitude 6 tremor struck with a record depth of 42.7 km and its epicenter was spotted at one kilometer away from Brgy. Talaga, also in Mabini town as reported by PHIVOLCS. The USGS maintains that the tremor is at Magnitude 5.9
The twin earthquakes was followed by another two more tremors making a record of four (4) earthquakes in 90-minute period.
The PHIVOLCS said the series of earth movement is part of the earthquake swarm cause by the movement of a newly-found local fault found in the Tingloy-Mabini area.|BALIKAS News
