GROUP 3 GRADE 10 SULTAN KUDARAT EARTHQUAKE AND ITS TYPE SCIENCE
INTRODUCTION An earthquake is a weak to violent shaking of the ground produced by the sudden movement of rock materials below the earth surface
OBJECTIVES EARTHQUAKE AND ITS TYPE To forsee the impact of earthquakes on buildings,bridges,tunnels,roadways,and other structures to minimize the risk of damage.
EARTHQUAKE
EARTHQUAKE What is earthquake? Earthquake refers to the result of a sudden release of energy in the earth’s crust that create seismic waves.
E ARTHQUAKE In earthquake there is four(4)different types of earthquake : Tectonic Collapse Volcanic Explosion
EARTHQUAKE Earthquake happens when the stress on the edge overcomes the friction
3 KINDS EARTHQUAKE 1.Shallow fault Earthquake A fault is a break in the rock beneath our feet. Shallow faul t quakes occur very close to the surface .There was a major quake on this seattle fault about 1,100 years ago .
3 KINDS OF EARTHQUAKE 2. Subduction Zone Earthquake The large earthquake ever recorded are subduction zone earthquake. They can last several minutes. Subduction zone shaking can occur along the while subduction zone.
3 KINDS OF EARTHQUAKE 3.Deep Earthquak e Deep Earthquake accur in the subducting ocean slab, Deep beneath the continental crust. In the pacific Northwest, Deep earthquakes about 50 km (30 km)beneath the surface.
TECTONIC EARTHQUAKE
TECTONIC EARTHQUAKE A tectonic earthquake or volcano earthquake is caused by the surface of the earth. Tectonic earthquake also produced by sudden movement along faults and plate boundaries. WHAT IS TECTONIC EARTHQUAKE ?
TECTONIC EARTHQUAKE Why is it called tectonic? Tectonics (from latin tectonicus;from ancient greek ( tektonikos ) pertaining to building.
EXAMPLE TECTONIC EARTHQUAKE
VOLCANIC EARTHQUAKE Volcanic (or volcanotectonic ) earthquakes those that occur inside volcanoes or close to them. Most earthquakes associated with volcanoes occur at comparatively shallow depths normally or less than 10 km. What is Volcanic Earthquake ?
VOLCANIC EARTHQUAKE Volcanic earthquake data Moving magma and volcanic fluids causes earthquakes. T hey occur swarms(many earthquakes occurring close together)before an eruption. They are caused by a liquid magma ,hot fluids,and gases forcing their way through he crust to reach the surface.
EXAMPLE OF VOLCANIC EARTHQUAKE
COLLAPSE EARTHQUAKE
COLLAPSE EARTHQUAKE What is Collapse Earthquake? A collapse Earthquake are small earthquakes in under ground caverns and mines that are caused by seismic waves produced from the explosion of rock on the surface.
COLLAPSE EARTHQUAKE Causes of Collapse Earthquake ? A collapse earthquakes in underground caverns and mines that are caused by seismic waves produced from the explosion of rock on the surface.
EXAMPLE OF COLLAPSE EARTHQUAKE
EXPLOSION EARTHQUAKE
EXPLOSION EARTHQUAKE What is Explosion Earthquake? ? An explosion Earthquake is an Earthquake that is the result of the detonation of a nuclear and/or chemical device.
EXPLOSION EARTHQUAKE What are the causes of explosion? An explosion caused by a rapid expansion of gas from chemical reactions or incendiary devices. Sign of an explosion is may be a very loud noises and vibration, fire ,heat or smoke, falling glass or debris, or building damage.
EXPLOSION EARTHQUAKE Basic facts? Explosion Earthquake are directly related to volcanic events,and they occur with volcanic explosions
EXAMPLE OF EXPLOSION EARTHQUAKE
INTENSITY
WHAT IS INTENSITY? In physics and many other areas of science and engineering the intensity or flux of radiant energy is the power transferred per unit are,where the areas measured in the plane perpendicular to the direction of propagation of the energy
INTENSITY Intensity can be found by taking energy intensity(energy per unit volume)at a point in space multiplying it by the velocity at velocity in which the energy moving.
MAGNITUD E
MAGNITUDE WHAT IS MAGNITUDE? A magnitude is a unit of measurement that is used to specify the size of intensity of an event. The property of relative size or extent (whether large of small)
HOW MAGNITUDE MOVE
MAGNITUDE/INTENSITY

WHAT YOU SHOULD DO IF THRE’S AN EARTHQUAKE
WHAT YOU SHOUD DO BEFORE AN EARTHQUAKE Create an earthquake safety plan for your loved ones,including pets. Identify safe places in each room in your home .
3.Practice drop,cover and hold with each member of your household. 4.Make or purchase an earthquake kit .
WHAT YOU SHOUD DO DURING AN EARTHQUAKE DROP to the ground;take COVER by getting under a sturdy table or other piece of furniture;and HOLD ON until th shaking stops.If there is no a table or desk near you,cover your face and head with your arms and crouch in an inside corner of the building.
DROP/COVER/HOLD
WHAT SHOULD YOU DO AFTER AN EARTHQUAKE Expects aftershocks and remember to drop,cover and hold. Look your self and get first aid kit if necessary. Asses your home or workplace for damage..
WHAT SHOULD YOU DO AFTER AN EARTHQUAKE 4.Look for a extinguish small fires if it safe . 5.Listen to the radio for updated emergency information and instructions.
TSUNAMI
WHAT IS TSUNAMI? Tsunami are ocean waves produced by earthquakes or underwater landslide. Tsunami are most often generated by earthquake-induced movement of the ocean floor.
EFFECT OF TSUNAMI In addition to loss life and mass injuries,Other potential impacts include damage to and distruction of homes and buisnesses,sports and harbors,cultural resources,utilities,and critical infrastructure and facilities .
