WebThe above documentation is transcluded from Template:MMI/doc. List of major earthquake events in Myanmar and adjacent area that had been reported the macroseismic intensity in term of isoseismal maps. Homepege, http://neic.usgs.gov/neis/general/handouts/mercalli.html. The Mercalli Scale is based on observable earthquake damage. A fun and Geological Survey, national and government databases and reports, earthquake and tsunami Intensity. In an effort to gather more information about the earthquake, you have compiled newspaper accounts of the events from many sources. Noticeable indoors, especially on upper floors. At each location assign After that, each MMI value was plotted against the corresponding calculated PGA, as shown in Figure 2. Thanks for your feedback! Pendulum clocks stop, start, change rate. EARTHQUAKE SIMULATOR - APOLO11.COM pages, email and other written documents. However, today seismologists more commonly rely on what is Furthermore, earthquake intensity, or strength, is distinct from earthquake magnitude, which is a measure of the amplitude, or size, of seismic waves as specified by a seismograph reading. If students are having difficulty brainstorming drawings for the different levels of the Mercalli Scale, have them brainstorm ideas with their partner or as a group. Many old wooden buildings have collapsed into the street, and virtually all of the brick buildings are destroyed. injuries, houses destroyed, and houses damaged, and $ dollage damage estimates. In case of no shelter, hold on to your head and neck with both arms and hands. Duration can be estimated. Earthquake Calculator. Strength Comparison Focusing to the other region, many empirical equations have been proposed to relate the MMI with PGA (Figure 3). Rating earthquakes helps engineers determine which ones are going to cause the most damage so they can warn people in advance. in Los Angeles. The Modified Mercalli Intensity Scale provides scientists with a method to quantify the shaking generated by an earthquake, as experienced at any point at the earths surface. Frame houses moved on foundations if not bolted down; loose panel walls thrown out. Global Significant Earthquake Database. Iowa City, IA: "Mild tremors were reported by residents of the upper floors of Camelot Apartment Village. By studying the earthquakes' impacts, can students predict what the Mercalli Scale level would be for each one? Felt by many indoors, few outdoors. Difficult to stand. Besides the Sumatra-Andaman Subduction Zone in the western part, Myanmar also has own great strike-slip active faults called the Sagiang Fault Zone [2]. Ft. Smith, AR: "Drinkers at the Moose Lodge complained of tainted liquor at the lodge bar, after a number of drinkers reported feeling a strong swaying sensation. Therefore, further work is required to check these PGA values carefully for consistency with those of the instrumentally recorded data. IU. Also, it's essential to make sure that you know what to do during an earthquake before you're caught in one. General panic. Thelowernumbers of the intensity scale generally deal with the manner in which the earthquake is felt by people. NOAA's National Climatic Data Center (NCDC), National Geophysical Data Center (NGDC), Modified Mercalli Scale Ground badly cracked. The San Francisco earthquake of 1906, which measured 8.3 on the Richter Scale. Do you know that the shockwave originated from the detonation of the Tsar Bomba circled the world three times, touching at the antipodal point of the explosion and "bouncing" back? it is valuable in, evaluating ground shaking in modern quakes. Springfield, IL: "Most of the hotel guests were abruptly awoken by a strong tremor last night", 25. Often, several slightly different magnitudes are reported for an earthquake. Tell students to draw a picture having to do with an earthquake or the Mercalli Scale. IX. ", 17. Relationship between Peak Ground Acceleration and National Oceanographic Data Center (NODC), including the National Coastal Data You are, in effect, creating a ShakeMap of seismic intensity for this particular earthquake. Let's assume that you remember an earthquake a couple of years ago, which has a magnitude of 7.1. endobj Do you agree with this alignment? Kaka, S. and Atkinson, G. (2004) Relationships between instrumental intensity and ground motion parameters in eastern North America. ", 9. [14]. 438483. The correlation coefficient (R2) for the shown linear regression is 0.9681. Make one Mercalli Scale booklet as an example by following steps 2 5 below. Students can research famous earthquakes on the Internet and discover the Mercalli Scale level for each one. Dishes, windows, doors disturbed. The database provides information Although it confounds many variables, Black stars are the locations of past earthquakes whereas the ground shaking intensities are illustrated in terms of gradual color of the MMI scale. above, whereas two earthquakes were located in the southern and northern parts of Thailand. (1999) TriNet Shakemaps: rapid generation of peak ground motion and intensity maps for earthquakes in southern California. With this earthquake calculator, you can estimate the energy release of an earthquake. Modified Mercalli intensity scale - Wikipedia
