MGB RXIII conducts Vulnerability and Risk Assessment

The Mines and Geosciences Bureau Regional Office No. 13 is currently conducting the Vulnerability and Risk Assessment (VRA) under the National Geohazard Assessment and Mapping Programme.

For the first quarter of 2017, the target municipalities of MGB RXIII are Magallanes and Las Nieves in the Province of Agusan del Norte. As for the second quarter, the Municipalities of Sibagat and Sta. Josefa in the Province of Agusan del Sur were assessed last April until the second week of May. For the rest of May until June, MGB RXIII will conduct VRA in the Municipalities of San Miguel and Tago in the Province of Surigao del Sur.

The Vulnerability and Risk Assessment is an activity following the 1:10,000 Scale Geohazard Mapping and Assessment which was concluded in 2015. The primary objective of VRA is to evaluate the existing vulnerability conditions within a municipality/city from rain-induced landslide and flood that could potentially harm the elements at risk such as people and infrastructures. The VRA could also provide technical support and information to the local government units (LGUs) in updating their Comprehensive Land Use Plan (CLUP) as well as for disaster preparedness and management.

The VRA is composed of both field assessment and table mapping analysis. Prior to the field assessment, the team pays a courtesy call on the LGUs in order to explain the objectives and methodologies of VRA for proper coordination and planning of the said activity. In addition, data needed for the output of the activity such as the administrative boundaries, road networks database and demographic profile, among others, are requested from the LGUs.

During the actual field assessment, GPS readings of the prominent structures like government facilities, school locations, churches, evacuation sites and establishments are gathered. Tracking of the existing road networks and trails are also recorded. Proposed barangay sites and evacuation centers, if present, are also assessed and located and information supplemented by interviews with the locals of the barangay. An important component of the VRA is the enhancement of the geohazard maps to render the exposure to hazard maps more up-to-date. The table mapping analysis utilizes ArcGIS software in generating the exposure maps. In the said maps, analysis is identified indicative of the vulnerability of the exposed elements at risk. These elements at risk include population, built-up areas and road networks.

The outputs of the Vulnerability and Risk Assessment are exposure maps (population at risk, built-up areas at risk and road networks at risk) and technical reports. An Information, Education and Communication (IEC) Campaign of the results of the said assessment will be conducted in the future.

MGB RXIII conducts Groundwater Resource and Vulnerability Assessment

The Mines and Geosciences Bureau Regional Office No. XIII conducted Groundwater Resource and Vulnerability Assessment from January to April 2017 in four (4) municipalities of Agusan del Norte and Province of Dinagat Islands.

A team of geologists, geologic aide, and laboratory technician from the MGB RXIII Geosciences Division conducted the said assessment in the following municipalities covering forty-seven (47) barangays:

Municipality                                     No. of Barangays
Las Nieves, Agusan del Norte                             20
Magallanes, Agusan del Norte                              8
Loreto, Province of Dinagat Islands               10
Tubajon, Province of Dinagat Islands              9

One of the functions of the Mines and Geosciences Bureau is the conduct of specialized researches and assessment of the country’s groundwater resources. The Groundwater Resource and Vulnerability Assessment Program is a major activity that the Mines and Geosciences Bureau has initiated to conduct as its contribution to the implementation of one of the provisions of the Clean Water Act (2004) stipulated in Chapter 3 Section 19-D which is to prepare and publish a national groundwater vulnerability map incorporating the prevailing standards and methodologies.

Theobjectives of the Groundwater Resource and Vulnerability Assessment Program are as follows:

  1. Assess the availability of groundwater on the various geologic formations in the entire country;
  2. Establish the quality/chemistry of groundwater in groundwater basins;
  3. Establish the potentials and limitations of available groundwater in the various groundwater basins; and
  4. Assess groundwater vulnerability of aquifers in the country.

Before conducting the said activity, the team paid a courtesy call on the Local Government Unit (LGU) – Municipal Disaster Risk Reduction Management Office (MDRRMO) and the Office of the Mayor of every municipality.

The team is tasked to make an inventory of all the water sources of every barangay during fieldwork.  Similarly, the team must geotag and document the water sources. Primary field data such as geology, geomorphology and the type of water source were gathered. The source of water could either be well type (shallow or deep), spring type, sinkhole, or river. Water samples were also collected per water source for the analysis of physical and chemical properties. The said properties were analyzed within 24 hours after the samples were collected. In addition, interviews were also conducted by the team in every barangay to gather secondary field data such as date of well construction, puroks supplied, location of the water source and other details in order for the team to note the past and present situation of the water sources.

MGB RXIII joins the conduct of CY 2017 1st Quarter National Simultaneous Earthquake Drill

The Mines and Geosciences Bureau Regional Office No. XIII joined the conduct of the CY 2017 1st Quarter National Simultaneous Earthquake Drill (NSED) on March 31, 2017 at 2:00 P.M. The primary purpose of the earthquake drill is to test the response capacity and capability of MGB RXIII employees to earthquake incidents.

Mr. Romeo M. Dalodado, MGB RXIII Geosciences Division Chief, gave a brief presentation on “How to Conduct an Earthquake Drill” that serves as a guide for employees to what should be done before, during and after an earthquake.  He also discussed the different stages in conducting the earthquake drill which include Planning/Organizing an Earthquake Drill, Developing the Earthquake Evacuation Plan, Orientation Prior to the Conduct of an Earthquake Drill and Actual Conduct of an Earthquake Drill.  Since the earthquake drill is performed quarterly every year, Mr. Dalodado reminded the employees of the established evacuation route and muster point/assembly area of the MGB RXIII Office.  A week before the earthquake drill, Mr. Dalodado gave a lecture on Earthquake and Seismic Hazards to MGB RXIII employees on March 20, 2017 in the aftermath of the magnitude 6.7 earthquake that hit Surigao City and some municipalities in the Province of Surigao del Norte.

The drill started with the one-minute buzzer alarm that indicates earthquake or ground shaking.  Everyone moved away from windows, glass or light fixture and performed the duck, cover and hold under desks, tables or chairs while the siren/bell sounded. After the “shaking” has stopped, everyone evacuated the office building and proceeded to go to identified evacuation areas using pre-determined routes.  Every division has an assigned observer who is tasked to take note of how the participants performed. When everyone has already settled in the muster point, headcount was then undertaken.

MGB RXIII employees diligently performed the earthquake drill to ensure that utmost consciousness, preparedness and response to disasters are achieved.

MGB ROXIII carries on with its Groundwater Resources Assessment Program

The Mines and Geosciences Bureau Regional Office No. XIII conducted the Groundwater Resources Assessment on September 13 to October 8, 2016 in the Municipalities of San Miguel, Bayabas, Cantilan and Carrascal in Surigao del Sur.

A team of geologists and geologic mappers from the Geosciences Division of MGB ROXIII was divided into two groups to conduct Groundwater Resources Assessment in all 56 barangays of the four aforementioned municipalities.

Aside from well inventory, the team surveyed every water source in each barangay. Water source can be a well or a spring. General information like geology and geomorphology of the area was noted.  Similarly, the well construction data such as well usage, well type, drilling method and pump type as well as the spring and the rock type data were taken during the survey. The team took water samples of each major water source in all barangays for pH and alkalinity test. After the survey at the end of each day, the geologists conducted the pH and alkalinity tests on all water samples taken on that same day as the water samples should be analyzed within 24 hours.

To generalize the results of the tests, the pH for water samples mostly ranged from 6.16-7.91 while the total alkalinity ranged from 50-200. Water can be determined as acidic if the pH is below 7, while the basic is above 7. Another task for the team was the distribution of the 1:10,000 scale geohazard maps to all barangays of the Municipalities of San Miguel and Bayabas in Surigao del Sur. The geologists explained the components and usage of the geohazard map to the barangay officials present during the visit of the Geoscience Division team.

A team of geologists and mapper from the Geosciences Division of MGB Regional Office No. XIII conducted the Coastal Geohazard Mapping and Assessment from July to August 2016 in southern coastal municipalities in the Province of Cebu as assigned by MGB Central Office.

coastal_2The fieldwork was divided in two phases. Five municipalities were covered during Phase 1 which was conducted from July 6-25, 2016 while four municipalities were covered during Phase 2 which was carried out from August 11-30, 2016. During the 1st phase of the fieldwork, the team assessed the coastal municipalities of Boljoon, Oslob, Santander, Ginatilan and Malabuyoc. The coastal areas in the Municipalities of Alegria, Badian, Moalboal and Alcantara were surveyed during the 2nd phase of the fieldwork.

The Coastal Geohazard Mapping and Assessment was conducted by mapping the shoreline through a handheld Global Positioning System (GPS) device. Beach profiling was also undertaken to determine the morphology of a beach and to compare beaches or coastlines in different locations. In the same way, evidence of erosion such as exposed roots of vegetation as well as eroded roads and infrastructure in the area was noted. The locals were interviewed to gather anecdotal records and typhoon history of the area as well.

The Coastal Geohazard Mapping and Assessment Program will give the public substantial information on coastal areas or shorelines that are experiencing erosion or prone to erosion and accretion. The said program aims to provide vital information to policymakers and the public in order to make them understand the risk of hazards, enhance preparedness, reinforce response, foster resilience and minimize the adverse impacts of disasters. On the same note, the output of this program serves as an important reference in adaptation and crafting land use, coping mechanisms and development and management plans of affected communities and stakeholders.

The workshop aimed to standardize the methodologies to be used and discuss the necessary procedures to be done such as rock sampling and appropriate map symbols. Every team (ROs and CO) was given 2 quadrangles  ̶̶̶̶  one raw quad and another quad for updating.

The four-day workshop included presentations of various resource speakers and selected MGB technical personnel. Discussions and agreements on the standard methods were made during the workshop. On the fourth day, a field practice was conducted in Tanay, Rizal.

VRA_2After the workshop, the teams proceeded to their assigned areas. The MGB ROXIII-GSD team mapped the Malolos Quadrangle from March 11 to 23, 2016.  The team paid a courtesy call on the officials of the Provincial Government of Bulacan and went to Malolos City as the first base camp.  After a week, the team moved to Baliuag, the second base camp, to easily map the eastern portion of the quadrangle.

The team mapped the Alupipey Quadrangle from March 28 to April 25, 2016.  The first base camp is the Municipality of Alfonso Castañeda, Nueva Vizcaya Province covering the south to western portion of the quadrangle. After two weeks, the team moved to Dupax del Norte covering the west to northern portion of the quadrangle.

VRA_3The last base camp is the Municipality of Nagtipunan, Quirino Province wherein the team covered the eastern half of the quadrangle. Unlike other highly accessible areas, the target area in Barangay Matmad is about 40-kilometer linear distance from the municipal proper and can only be accessed by pump boat via Cagayan and Casecnan Rivers.  The team fly-camped for three days and two nights to reach Matmad where they mapped the remaining portion of the quadrangle.

After the geologic quadrangle mapping activity, the MGB ROXIII-GSD team returned to Surigao City.
