There are 100 volcanoes in the Philippines listed by the Smithsonian Institution's Global Volcanism Program (GVP) at present, [6] of which 20 are categorized as "historical" and 59 as "Holocene". [6] The GVP lists volcanoes with historical, Holocene eruptions, or possibly older if strong signs of volcanism are still evident through thermal ...
The Philippines is assigned an international dialing code of +63 by ITU-T. Telephone numbers are fixed at eight digits for area code 02 , and seven digits for area codes from 03X to 09X , with area codes fixed at one, two, or three digits (a six-digit system was used until the mid-1990s; four to five digits were used in the countryside).
