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

Use the Earthquake Data (1973-2012) from the previous question to answer the following
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. (
7 Points
)
(b)
What insights do you obtain from the density map you created in part a? Explain. (
6 Points
)
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.
[Hint: you need to use the variables “
Longitude
”, “
Latitude
”, and “
Magnitude Richter
” in your
visualization.]
