Today, we are going to look at the Mercalli Scale's damage rating and create a booklet to help inform citizens of potential danger.

[7] This became known as the "Mercalli–Cancani scale, formulated by Sieberg", or the "Mercalli–Cancani–Sieberg scale", or simply "MCS",[8] and used extensively in Europe. [10] Wood and Neumann also had an abridged version, with fewer criteria for assessing the degree of intensity.

The Mercalli Intensity Scale measures the intensity of an earthquake by observing its effect on people, the environment and the earth’s surface. In 1904, Adolfo Cancani proposed adding two additional degrees for very strong earthquakes, "catastrophe" and "enormous catastrophe", thus creating a 12-degree scale.

A summary of intensity prediction equations is available.

Dishes, windows, and doors are disturbed; walls make cracking sounds. From the modeling we see that weak effects of Degree III on the Mercalli Scale are perceptible up to 172 km away from the epicenter, and the stronger effects of V Degree are contained within a radius of 56 km . Felt by all, and many are frightened. Brainstorm with the students how they might illustrate one of the pages. Understand how a community could use the Mercalli Scale. Cut all necessary paper needed for the class activity. Layer the four pieces of white copy paper in one stack with one piece of construction paper on top for the cover. [3] Mercalli's second scale, published in 1902, was also an adaptation of the Rossi–Forel scale, retaining the 10 degrees and expanding the descriptions of each degree. Students learn about the Mercalli Scale for rating earthquakes.copyrightCopyright © http://upload.wikimedia.org/wikipedia/commons/c/c7/US_Navy_110320-M-0145H-063_A_large_ferry_boat_rests_inland_amidst_destroyed_houses_after_a_9.0_earthquake_and_subsequent_tsunami_struck_Japan_March.jpg. Damage is negligible in buildings of good design and construction; but slight to moderate in well-built ordinary structures; damage is considerable in poorly built or badly designed structures; some chimneys are broken. After this activity, students should be able to: Each TeachEngineering lesson or activity is correlated to one or more K-12 science, The expendable cost is the estimated cost of supplies needed for each group of students involved in the activity. Ask the students: With Words and Pictures: Have students write a sentence on the bottom of each page of their information booklet describing their illustration of the Mercalli Scale rating.

If engineers can develop better technology for predicting the size and force of earthquakes, then cities and communities can work to keep themselves from harm. [20][23] The colors and descriptive names shown here differ from those used on certain shake maps in other articles.

Damage is total. The effects of any one earthquake can vary greatly from place to place, so many MMI values may be measured for the same earthquake. Using a deck of cards or by calling random numbers between 1 and 12, have the students show their drawing of what would happen during an earthquake with that Mercalli rating. Intensity scales empirically categorize the intensity of shaking based on the effects reported by untrained observers and are adapted for the effects that might be observed in a particular region.

The extent of damage is rated on the Mercalli Intensity Scale. All 100,000+ K-12 STEM standards covered in TeachEngineering are collected, maintained and packaged by the Achievement Standards Network (ASN), Mercalli ratings, which are given as Roman numerals, are based on largely subjective interpretations. Students can research famous earthquakes on the Internet and discover the Mercalli Scale level for each one. Damage is considerable in specially designed structures; well-designed frame structures are thrown out of plumb. www.teachengineering.org/activities/view/cub_natdis_lesson03_activity3, Search curriculum by Common Core standards, Natural Disasters: Earthquakes, Volcanoes, Tornadoes & More. Thanks for your feedback! Review the purpose of the Mercalli Scale with the students, as described in the Introduction/Motivation section. Tell students to label and illustrate the cover.
