SCIENCE 6/4

• Intensity - the strength of the earthquake
• Volcano - an opening in Earth's crust that erupts when pressure builds up
• Cinder cone volcanoes - volcanoes that have circular or oval cones
• Composite volcanoes - volcanoes that have steep sides
• Shield volcanoes - volcanoes look like the shape of a bowl or shield, with long, gentle slopes made from basalt lava flows.
• Lava dome volcanoes - volcanoes that are formed by thick lava / also be formed within inside of another volcano
• Active volcanoes - that have recently erupted, have/had at least one eruption for the last 10,000 years
• Dormant volcanoes - once an active volcano that has not erupted for 10,000 years but still has the potential to erupt again.
• Extinct volcanoes - volcanoes that no longer expected to erupt again
• Pacific Ring of Fire - 40,000 circle of interconnected fault lines around the Pacific Ocean.
• Volcanology - Study of Volcanoes
• Magma - Hot molten material
• Lava - The hot molten material when it goes out of the volcano
• Ground rupture - the mark of the intersection of the fault within the surface of the earth
• Ground shaking - disruptive vibration of the ground in all directions during an earthquake
• Liquefaction - the phenomenon wherein the soil is weakened by the earthquake shaking
• Tsunami - series of waves caused by earthquakes under the sea
• Lava flow - it will not be usable for a long time as lava deposits harden and solidify
• Ashfall - shower of fine-to-coarse-grained fragmented materials from a volcanic eruption
• Lahar - a thick mixture of volcanic materials & water that rapidly flows when in liquid phase but solidifies and hardens afterward
• Volcanic gases - a mixture of different gases is released during a volcanic eruption, with most of it being water vapor
• Pyroclastic flow - fast, raging flow of volcanic materials made by a combination of ash, rocks, and hot gases.
• NDRRMC - National Disaster Risk Reduction and Management Council
• PRC - Phillipine Red Cross
• PHIVOLCS - Philippine Institute of Volcanology and Seismology
• BFP - Bureau of Fire Protection
• Earthquake - is a weak to violent shaking or trembling of the ground caused by the sudden movement of the rocks below the surface of Earth.
• Faults - are lines or cracks in Earth's surface that are caused by the movement of the plates
• Tectonic earthquake - a type of earthquake caused by sudden movements along the tectonic faults and plate boundaries
• Volcanic earthquake - a type of earthquake caused by volcanic activities
• Collapse Earthquake - a type of earthquake that occur in caverns or mines
