It’s a shaking of the ground, or rolling of the earth’s surface. It is also release in the form of seismic waves.
Earthquake
an abrupt motion of the earth’s crust as a result of its energy being
It’s a place where the earthquake initiated?
Hypocenter or Focus
It is produced by explosive volcanic activity or magma ejected beneath the crust.
Volcanic Earthquake
This is generated from the built-up energy within the rocks due to the movement of faults.
Tectonic Earthquake
This occurs from the explosion of chemicals or nuclear devices.
Explosive Earthquake
This happens due to the sudden collapse of caves and mines.
Ground Collapse
What do you call the strong vibrations during earthquake?
Ground Shaking
When earthquake happens what do you call when cracks appear on the surface?
Ground Ruptures
What do you call the process when water-saturated soil and sediments that an earthquake greatly disturbs, the stability of the soil is compromised?
Liquefaction
What do call the cause of earthquake that abrupt lowering or sinking of the ground surface?
Ground Subsidence
This refers to the quantity of seismic energy in an earthquake?
Magnitude
What tool do you use when measuring the magnitude of the earthquake that is based on the logarithm of the seismic wave’s amplitude?
Seismograph
This is an essential tool used to identify areas that can be readily affected by or prone to natural hazards.
Hazard Map
These are volcanoes that either regularly erupt or known to erupt within the last 600 years as documented or reported?
Active Volcano
These are volcanoes that erupted in the last 10,000 years, except that these volcanoes have not erupted for an extremely long period in time.
Inactive Volcano
These volcanoes have no record of eruptions.
Extinct
This is the formation of lava domes from viscous magma that solidified around the vent.
Dome Growth
This kind of flow is composed of an extremely hot mixture of rock fragments, expanding gasses and ashes.
Pyroclastic Flow
These are the mixture of gases during volcanic eruption, includes; water vapour, hydrogen sulphide, sulphur dioxide and ect.
Volcanic Gases
What do you call the opening of the volcano?
Vent
This is where the magma is collected before eruption.
Magma chamber
This is a large, tall volcano made up of layers of hardened lava, ash, and rocks from many eruptions. These volcanoes are known for their classic, cone-shaped appearance and can be very big.
Stratovolcanic or Composite
This referred to as mudflow or volcanic debris flow, which is composed of a mixture of volcanic debris and water that has the consistency of wet concrete. It moves down the slope of a volcano and usually finds its way into rivers.
