Phivolcs says 4:19 shake
still Oct 2013 aftershock
TAGBILARAN CITY, August 11 (PIA) --The tremor that awakened the fears of most Boholanos when it came 4:19 is not another earthquake but is still considered an aftershock of the October 15, 2013 quake.
Bohol Philippine Institute of Vulcanology and Seismology (PHiVOLCS) Ubujan station chief Engr. Nolan Evangelista clarified that unless the tremor surpassed the 7.2 magnitude earthquake in 2013, and occurs within the 2013 earthquake rupture areas, these could only be considered aftershocks.
According to Phivolcs, the 4.2-magnitude earthquake was felt in at least seven towns and Tagbilaran City in Bohol, its epicenter situated about two kilometers northeast of Cortes, the origins trace at six kilometers deep.
Speaking during an interview aired by a local radio station, Engr. Evangelista explained that even when the 4:19 shake did produce smaller shaking as reported by residents of Antequera, Bohol, these were not even felt by the sensitive seismograph his office keeps.
With the tremor coming back after residents have not heard or felt any substantial shaking since after a few months from the big one in 2013, several have opted to stay outside of their homes despite being too early in the morning.
The shaking, according to Phivolcs lasted about 2 seconds but several observers noted a far longer shaking, some saying it was about 5-6 seconds.
Engr. Evangelista however explained that the intensity of the aftershock can he heightened by the condition of the soil where one is located.
On loose and less compact grounds, the shaking would persist longer than the two seconds recorded by seismographs.
Shaking which would last that long, 5-6 seconds can already be devastating, meaning the ripple effect could produce a much longer movement, the Japan trained Boholano seismologist said. (rac/PIA-7/Bohol)
