Evalou Concepcion A. Agustin, in partnership with the City Government of Pasig through its mayor, Honorable Victor Ma. Regis N. Sotto. The writers utilized the standards set by the K to 12 Curriculum using the Most Essential Learning Competencies (MELC) in developing this instructional resource. This learning material hopes to engage the learners in guided and independent learning activities at their own pace and time. Further, this also aims to help learners acquire the needed 21st-century skills especially the 5 Cs, namely: Communication, Collaboration, Creativity, Critical Thinking, and Character while taking into consideration their needs and circumstances. In addition to the material in the main text, you will also see this box in the body of the module: Notes to the Teacher This contains helpful tips or strategies that will help you in guiding the learners. As a facilitator, you are expected to orient the learners on how to use this module. You also need to keep track of the learners' progress while allowing them to manage their learning. Moreover, you are expected to encourage and assist the learners as they do the tasks included in the module. For the Learner: Welcome to the Disaster Response and Risk Reduction Self-Learning Module on Geological Hazard! This module was designed to provide you with fun and meaningful opportunities for guided and independent learning at your own pace and time. You will be enabled to process the contents of the learning material while being an active learner. This module has the following parts and corresponding icons: Expectations - This points to the set of knowledge and skills that you will learn after completing the module. Pretest - This measures your prior knowledge about the lesson at hand. Recap - This part of the module provides a review of concepts and skills that you already know about a previous lesson. Lesson - This section discusses the topic in the module. Activities - This is a set of activities that you need to perform. Wrap-Up - This section summarizes the concepts and application of the lesson. Valuing - This part integrates a desirable moral value in the lesson.

Sand RECAP https://www.independent.co.uk/voices/taal-volcano-eruption-disaster-philippines-mental-health-a9284361.html FIGURE 1: A resident evacuating after the taal volcano erupts Taal volcano erupted on January 12, 2020, it is 43 years after its previous eruption in 1977 it was a devastated having 160,000 evacuees in Batangas affected in the volcanic eruption and 39 people have recorded death during this disaster. 1. How do you define a volcanic eruption? 2. Cite an example of the “positive effect of eruption”? 3. What are the precautionary measures that you do with your family before, during, and after a volcanic eruption? LESSON Geological hazards are defined as extreme natural events in the crust that will create a treat for humanity or any living things. And some examples of these geological hazards are earthquakes, volcanic eruptions, and more. But there are more geological hazards or other geological hazards namely landslide and sinkhole that we will tackle this lesson. FIGURE 2: Rainfall induced Landslide https://blogs.agu.org/landslideblog/2018/09/21/naga-city-landslide-1/ FIGURE 3: Sinkhole https://www.sott.net/article/300725-5-sinkholes-discovered-in-Negros-OrientalPhilippines How do you describe the pictures above? Landslide is the movement of debris rocks or any particles in the earth in the downslope. And one of the common examples of a landslide is the “rainfall-induced landslide Rainfall-induced landslide is a type of landslide which comes with water in it so aside from debris and rocks it also has water due to heavy RAINFALL. The sinkhole is a naturally occurring geological hazard below the surface that collapse eventually some geologist called it “karst terrain” a specific type of terrain that is from due to dissolving of rock beneath the surface. The most common type of rock that is dissolved in this is limestone. There are major types of a sinkhole and they are: Solution sinkhole- it is the most common sinkhole it formed when the soil is very thin on the surface and exposing the bedrock once it starts to rain the soil are carried out and eventually leaving a hole. Cover collapse sinkhole- the most dangerous type of all the sinkholes happened when water penetrates in the topsoil going to the limestone and dissolve it eventually until the surface collapse. Cover subsidence sinkhole- most common with a surface that semipermeable for example is sand when the limestone is dissolved below the surface due to rain particles are eventually moved downward to replace the space of a limestone. ACTIVITIES ACTIVITY 1 Complete the Venn diagram below by defining the two terms then, identify its similarities and difference. ACTIVITY 2 DIRECTIONS: Create a timeline on the following event of the sinkhole in the Philippines Manila city sinkhole June 08, 2010 Badian Cebu Sinkhole April 29, 2017 Baguio City Sinkhole June 08, 2015 Benguet Sinkhole August 02, 2016 Negros oriental Sinkhole August 22, 2015 What do you think is the reason why this place has a sinkhole? What month do you think is prone to a sinkhole, what do you think is the reason Why? ACTIVITY 3 DIRECTIONS: Complete the crossword puzzle below. Across 1. Natural occurring geological hazards below the surface that collapse eventually some geologist called it “karst terrain” 2.
