HOMEWORK 4
Make sure to upload onto Canvas both your completed Homework
document in Word/PDF format and
Tableau Packaged Workbook in TWBX format
(see the screenshot below).
First, download the Earthquake Data (1973-2012)
from Canvas. This data-set contains information on
the magnitude of earthquakes in Richter scale around the globe over the duration of 1973 through 2012.
Next, connect this data-set to Tableau Desktop
and answer the following questions, taking into
consideration what you learned from the class. Make sure to upload onto Canvas both your completed
Homework
document and Tableau worksheet

questions:
(a)
Recreate the following density map displaying the regional distribution of earthquake severity
around the globe. Darker areas are associated with larger earthquakes in Richter scale. (

The map describes the severity of earthquakes around the world from 1973 to 2012. Asia emerged as the epicenter of catastrophic earthquakes during this period, experiencing a substantial concentration of severe tremors. Following closely, the Australia and Oceania region faced a notable frequency of devastating earthquakes. In Central America and South America, although seismic activity was evident, the intensity and severity of quake tremors were relatively less pronounced. Europe and the Middle East also grappled with a significant number of earthquakes, yet the level of devastation was not as severe when compared to the catastrophic occurrences in Asia and the Oceania region. This geographical variance in earthquake severity underscores the diverse and dynamic nature of seismic hazards across the world during those four
decades.

A symbol map illustrating the total number of eligible voters across the United States provides a clear and striking visualization of the distribution of voting-eligible population. California emerged as the most populous state in terms of eligible voters, boasting a significant 26 million individuals eligible to vote. Following closely are the populous states of Texas, Florida, and New York, with 19 million, 16 million, and 10 million eligible voters, respectively. The concentration of eligible voters in these states aligned with their large populations and diverse demographics. In
contrast, Wyoming stood out as the state with the lowest number of eligible voters, presenting a stark contrast to the populous states. This disparity in voter population underscores the electoral influence that larger states like California and Texas possess, while highlighting the need for equitable representation and engagement in the democratic process across all states, regardless of size or population.

Minnesota notably stood out with the highest voter turnout, an impressive 80%, highlighting the
state's strong commitment to civic involvement. Furthermore, states such as Oregon, Washington,
Colorado, Maine, and Wisconsin demonstrated substantial voter turnout, each registering an
impressive 76%, showcasing their proactive and engaged electorates. On the other end of the
spectrum, Oklahoma recorded the lowest voter turnout at 55%, emphasizing the necessity for
increased efforts to boost civic participation and voter engagement within the state. Similarly,
Arkansas closely followed with a turnout of 56%, indicating the importance of enhancing civic
involvement and implementing outreach strategies to encourage participation in the democratic
process. This map vividly showcases the disparities in voter turnout across states, underscoring the
significance of fostering a culture of civic engagement and establishing accessible avenues for
citizens to exercise their right to vote.
[Hint: you need to use the variables “
VEP Turnout Rate (Total Ballots Counted)
” in your
analyses.]
