Survey by Group 3

  1. 1. ROAD SURVEY<br />Matina Shrine Hills<br />Gimoto, Lilibeth P.<br />Huelva, Marco Julio<br />
  2. 2. Introduction<br /> <br /> Structural geology is the study of the three-dimensional distribution of rock units with <br />respect to their deformational histories. The primary goal of structural geology is to use measurements of present-day rock geometries to uncover information about the history of <br />deformation (strain) in the rocks, and ultimately, to understand the stress field that resulted in the <br />observed strain and geometries. This understanding of the dynamics of the stress field can be <br />linked to important events in the regional geologic past; a common goal is to understand the <br />structural evolution of a particular area with respect to regionally widespread patterns of rock <br />deformation (e.g., mountain building, rifting) due to plate tectonics.<br /> <br />
  3. 3. Location<br /> <br /> We surveyed a 250 meters cemented highway along city road in Shrine Hills, Matina, <br />Davao City which consist a total of 2,000 square meters. It is a commercial lot where <br />many telecommunication towers, television and radio stations located. Shrine Hills is 1 <br />kilometer away going to GAP (a leisure park) and only 24 meters frontage to the city <br />road. It is good for residential to avoid noise and pollution of the city.<br />
  4. 4. Observation<br /> <br />
  5. 5. Findings <br /> <br /> <br /> The sediments in the area are unstable. Every layer was formed in ancient times under the <br />sea and is of a different type. Some are fine sand or clay, some are coarser, and some are <br />pebbles or broken sea corals. All these different layers will react differently; once they <br />are exposed to or soaked with water. They will begin to slide over each other. Nature <br />always balances out and rearranges itself to lower levels because of gravity. Luckily, <br />trees, greenery and existing rock formations, all slow down this process.<br /> <br />
  6. 6. Findings <br /> <br /> <br />But by cutting trees, cutting rock-formations to build roads and houses, changing the <br />natural waterways, we risk triggering a speedy natural re-balancing, which mostly <br />involves landslides, floods, loss of properties and in the worst case loss of lives. <br />Examples of that has been headline news in the Philippines and all over the world. Just <br />imagine, what will happen with a combination of heavy rains and an earthquake. This <br />could happen, since the same fault line that runs under the condemned Sports Dome, also runs <br />partly along the Shrine Hills.<br /> <br />
  7. 7. Our Hills very recently experienced the first signs of man-made disasters like:<br /> <br />Juario Village: rock falls and landslides in 2009, death of a child in a chapel in 2007, more rock falls and landslides in 2006, etc…<br /> <br />Nacilla Village: houses destroyed in 2000 and movement of the soil (sediment layers) since then.<br /> <br /> <br /> <br /> <br />
  8. 8. Conclusion<br /> <br /> We have a landmark in the middle of the city, which is rare, green and beautiful, oxygen-<br />producing, helping to keep local temperatures down and creating cool breezes. Which <br />city in the world isn’t jealous of that and we might give it up.<br />What will the future generations say about us? Will they say that we acted as real caring <br />“City-Fathers”, by open-mindedly, resourcefully and responsibly making decisions for <br />the good of the people? Or will they say that we light-headedly acted with dollar-signs in <br />the eyes , thinking that no information is good information ?<br />
  9. 9. The City Government should preserve Shrine Hills as well as the people. It is one of the <br />many resources of Davao City that must be proud of. <br /> We should not focus on a short term income gain of the land owners. Temporary<br /> employment of the residence. Higher tax income of our government. They should choose that <br />many people can benefit and gives us happiness forever.<br /> Let us all unite to stop further destruction of our Shrine Hills, the Green Lungs right in <br />the middle of the city and declare it as a PROTECTED AREA.<br /> <br />
  10. 10. Recommendations<br /> <br /> I recommend that subdivision projects shall be located within suitable sites for housing<br />and outside hazard prone areas and protection areas as provided for by pertinent laws. Critical<br />Areas (E.g. areas subject to flooding, landslides and those with unstable soil) must be avoided. <br /> The development should be environmental friendly and considers climate change <br />realities. It should be beneficial to the present generation but does not compromise the rights and <br />interests of future generation.<br /> <br /> <br />
