The point at which layers of rock shift in relation to one another is called the focus. Directly above the focus, a second point called the epicenter marks the corresponding point of highest-intensity shock on the surface. Shock waves propagate like ripples from the focus and epicenter, decreasing in intensity as they move outward.  Sudden earth movements along geological faults.There are two kinds of quakes, tectonic(plates that make up the earth's crust cause a fault) and subduction-zone quakes.Volcanic activity when lava builds up to high pressures and energy is release in the form of an eruption.

The magma chamber collects the magma that is pushed to the surface in an eruption. examples can be; Destructive, with large lava flows or explosive activity. Hot debris particles called pyroclastic are expelled during violent explosions. Heavier pieces land near the crater and lighter pieces can be carried by the wind for hundreds of miles.Non-destructive, with little release of solids or magmatic liquid. These eruptions occur when the magma is more fluid and contains less gas. The solids or magma rocks and lava cools on it's slope.]]> 2017-10-28 00:15:05 UTC https://padlet.com/staltai001/xarwlhumbfft/wish/201372978 staltai001 https://padlet.com/staltai001/xarwlhumbfft/wish/201372991 The Ring of Fire is a major area in the basin of the Pacific Ocean where a large number of earthquakes and  volcanic eruptions occur.
