GEOLOGY

Detailed explanation-1: -An earthquake occurs when the tension in the normal movements within the earths crust increases leading to formation of massive waves creating trembling on the earths surface. Thus, volcanic eruptions can cause earthquakes because of the massive amount of energy that is released during an eruption.

Detailed explanation-2: -Volcanically-caused long period earthquakes are produced by vibrations generated by the movement of magma or other fluids within the volcano. Pressure within the system increases and the surrounding rock fails, creating small earthquakes.

Detailed explanation-3: -Volcanic earthquakes, discovered by L. Palmieri at the Vesuvius Observatory in 1855, are caused by sudden opening of channels in crustal rocks, rapid changes of motion of magma, excessive accumulation of gas pressure in the crust, roof collapses of subterranean channels emptied of magma, and so on.

Detailed explanation-4: -The Ring of Fire, also referred to as the Circum-Pacific Belt, is a path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes. The majority of Earth’s volcanoes and earthquakes take place along the Ring of Fire.

Detailed explanation-5: -Earthquakes and volcanoes cause damage not only to humans and their structures, but to the environment and wildlife. Earthquakes can cause damage by shaking, tsunami’s, and landslides. Volcanoes can cause damage by ash flows, release of gases, mudflows, lava flows, and landslides.
