GSP History

The Geological Society of the Philippines was organized on VJ Day, September 2, 1945, amidst the ruins of the newly liberated City of Manila when a group of geologists (mostly Americans) attached to the office of the Chief Engineer, GHQ AFPSC, met with a group of Filipino geologists and mining engineers under the chairmanship of Lt. Col. H. G. Scherick.  Credit for the initiation of the movement which led to the founding of the Society goes to Major Robert N. Williams and to Dr. Jose M. Feliciano.  Of the 62 original or charter members, 39 were Americans, one Australian, and the rest Filipinos.

In this historic meeting, the late Dr. Jose . Feliciano, former head of the Department of Geology and Geography of the University of the Philippines was unanimously elected first President of the Society, with Dr. Victoriano Elicaño as Vice President, Mr. Francisco Paguirigan as Secretary-Treasurer, and Mr. Ramon Abarquez as Editor.

The Philippine government has given due recognition to the Society when, by legislation, it required that one of the members of the Commission on Volcanology must come from the Geological Society of the Philippines.  Motivated by the strong desire to uphold the standards of the geological profession in the country, the Society sponsored in Congress House Bill 401 and worked until it was enacted and passed into law last June 19, 1965.  Known as Republic Act 4203, it regulates the practice of the geology profession in the Philippines.  Article I, Sec. 2 of the said law provides that the members of the Board of Examiners for Geology shall be appointed by the Geological Society of the Philippines.

To celebrate its 14th anniversary, the Society convened its first geological convention in Manila from January 9 – 11, 1958.  Delegates from the geological societies of Japan, Nationalist China, United States, Australia and South Korea attended.  Fifteen papers were read and the discussions created lively interest on current geological problems.  The Society gained wide support from the different mining companies which helped in making the first convention a success.  During the convention, distinguished achievement awards were given to Mr. Earl M. Irving and Mr. Juan S. Teves.

To spur mineral resources development in the country and to support the administration’s various economic programs, the Society convened the “2nd Geological Convention and First Symposium on the Geology of the Mineral Resources of the Philippines and Neighboring Countries” on January 11 – 14, 1967.

In the late 1966, the Geological Society of the Philippines was incorporated in order to effectively pursue the different plans and activities toward the attainment of its objectives.
