MGB RXIII accomplishes 2018 Geologic Quadrangle Mapping target

Geologic quadrangle mapping is one of the regular mandated functions of the Mines and Geosciences Bureau. It aims to produce updated reconnaissance geological maps of 1:50,000 scale. Each quadrangle map sheet covers a specific area of the Philippines which is about 48,600 hectares on the average. The index map showing the distribution of these quadrangle maps is maintained by the National Mapping and Resource Information Authority (NAMRIA). Under the quadrangle mapping activity, it is envisioned that the entire land area of the country will eventually have a geological map of 1:50,000 scale. The topographic map of each quadrangle sheet is printed and sold by NAMRIA. These topographic maps are used as base maps for the reconnaissance geological mapping.

In Caraga Region, there are 54 quadrangle sheets covering the entire region; of these, only 20 quadrangle sheets have published/unpublished geology while the rest are still to be mapped. The CY 2018 target of MGB RXIII which comprised five (5) quadrangle map sheets, namely three (3) quadrangle maps that partly cover the Siargao Group of Islands and two (2) quadrangle maps in Dinagat Islands, has been accomplished. Legwork was carried out in Siargao Island-covered quadrangle sheets in the first semester of 2018.

Quadrangle sheets covering Dinagat Group of Islands were selected as a target to align with the request of Province of Dinagat Islands to segregate a portion of land in the Municipality of San Jose from the Surigao Mineral Reservation for the development of a Government Center that will cater to the establishment of various government offices.

The reconnaissance geological mapping and verification of the Wilson and Dinagat Quadrangles was scheduled to be carried out in the second semester of CY 2018. For the Wilson Quadrangle map sheet, the area covered by ground verification during the period of August 6 until mid-September 2018 is around 25,000 hectares that include the islands/islets on the eastern part of the main landmass.

The geologic mapping activity continued on the northern part of Dinagat Quadrangle and was concluded in the middle part of October 2018 in areas covering the southern part of the quadrangle particularly the island barangays of Surigao City. Approximately, the total coverage of mapping is 15,000 hectares. The field mapping was carried out by the following personnel of the Geosciences Division: Noel G. Lumague, Supervising Geologist; Kate A. Boquilon, Senior Geologist; Janeth S. Aparri, Geologist; and Dionesio A. Surigao, Geologic Aide.

The drafting of geologic reports and map digitization are ongoing.

MGB RXIII chemists rise to the challenges of 33rd Philippine Chemistry Congress

Rising to Challenges (RCh) is the theme of the 33rd Philippine Chemistry Congress which was held on May 30-June 1, 2018 at the Philippine International Convention Center in Roxas Boulevard, Manila. The theme is not only a fitting abbreviation for registered chemists (RCh) but it intrinsically expresses the spirit of the present-day chemistry community that uses chemistry as a key to unlock the solutions to many challenges. Two chemists from the Mines and Geosciences Bureau Regional Office No. XIII joined over a thousand professionals, participants, researchers and paper presenters from the chemical industry and the academe as well as policymakers and leaders from government partner institutions in the annual gathering of chemists which has been in existence for thirty-three years.

Esteemed guest speakers highlighted the topics on chemical security, efficient regulation of chemicals of concern, laboratory accreditation, environmental chemical regulations, water analysis and the chemicals weapons convention. Discussions and paper presentations revolved around the role of the chemical industry in pushing innovations that can sustain economic growth, stimulating research and development agenda in close collaboration with the academe and defining more targeted interventions in order to sustain momentum of economic resurgence.

With the passage of the Chemistry Law (RA 10657), chemical laboratories are now seeking accreditation, debutante laboratory technicians are getting licensed and the academe has its hands full in the preparations for the soon-to-be implemented post K-12 Chemistry Curriculum. This also remains the biggest challenge for MGB chemical laboratories along with their compliance with stringent requirements to secure the necessary permits and their ability to sustain high quality standards in the delivery of reliable and accurate laboratory services.

At the end of the congress, the directions for the development of chemistry in the Philippines was discussed by Dr. William G. Padolina, current President of the National Academy of Science and Technology and former Secretary of the Department of Science and Technology. Discussants included representatives from the Professional Regulation Commission, chemical industry, higher education, research group and the K-12/STEM program of the Department of Education. Some of the proposed roadmaps are the acceleration of the development and retention of a critical mass of Filipino talents in chemistry and the enhancement of the transformative role of chemistry as a catalyst for change in steering the nation towards resilience and prosperity.

MGB RXIII conducts Vulnerability and Risk Assessment in Surigao del Sur

The Mines and Geosciences Bureau Regional Office No. XIII conducted the Vulnerability and Risk Assessment (VRA) on April 16 to 30, 2018 in the Municipalities of Marihatag, Cagwait and Bayabas, Province of Surigao del Sur.

The said assessment was conducted by a team of geologists and an on-the-job trainee from Negros Oriental State University. The team formed two groups that were assigned in every barangay to perform geotagging in order to tag the essential landmarks such as barangay halls, health centers, schools, multi-purpose buildings, purok centers and other establishments per purok, district or sitio in all barangays of the aforementioned municipalities. The purpose of tagging landmarks or establishments is to get their exact global positioning system (GPS) coordinates and plot them on the map. Moreover, building materials and road networks were noted for data gathering. The threat of any hazard or element of risk to landslide or flooding within those establishments was also verified. Interviews with some residents in the area were also made to note the scenario and details of any disaster they have experienced so as to update the geohazard maps generated by MGB RXIII.

All the municipalities were assessed and the elements at risk identified.  Similarly, the team took note of every road’s status (concrete or non-concrete) and building materials (light or concrete). The areas where flooding and landslide susceptibility occurs (rated from low, moderate, high and very high) were also observed.

The outputs of the VRA are technical reports and Risk Maps that incorporate the population, roads and infrastructures at risk of the said hazards. These reports and maps will essentially assist the Local Government Units in their planning and pre-disaster risk activities.
