My Mercalli Scale TASK: Design your own Mercalli Scale using the descriptions below. Draw a diagram to illustrate the damage caused by the 6 measures highlighted in red. I Felt by almost no one. II Felt by very few people. III Tremor noticed by many, but they often do not realise it is an earthquake. IV Felt indoors by many. Feels like a truck has struck the building. V Felt by everyone; many people are awakened. Swaying trees and poles may be observed. VI Felt by all; many people run outdoors. Furniture is moved. VII Everyone runs outdoors. Poorly built structures considerably damaged. Slight damage elsewhere. VIII Specially designed structures damaged slightly, others collapse. IX All buildings considerably damaged, many shift off foundations. Noticeable cracks in the ground. X Many structures destroyed. Ground badly cracked. XI Almost all structures fall. Bridges wrecked. XII Total destruction. Waves seen on ground surfaces. LO: To explain how earthquakes are measured
