Task 1: Analyse how neighborhoods should be prioritsed for response and find out which parts of the city are hardest hit

Emergency responders will base their initial response on the earthquake shake map. Use visual analytics to determine how their response should change based on damage reports from citizens on the ground. How would you prioritize neighborhoods for response? Which parts of the city are hardest hit? Limit your response to 1000 words and 10 images.

1.1 Analysis of damage reports by time and average damage on location The damage reports are analysed at the time they are received. When reports are received, cities which have the the highest average damage will be looked into. The number of reports is indicated by the size of the circle marked on the map.
1.2 Analysis of damage reports by average damage of objects When a location is selected based on the average damage, the average damage of each object can then be seen in comparison to other location based on the point in time. For instance, location 3 is selected, and on the left, the damage on each item can be seen relative to other locations. As such, the respondents are able to see what they should prioritise for this location and if other location has worse damage than the current location. Looking at the breakdown of damage on location 3, the damage on sewer and water is not the highest at this point and there is another location (Location 4) there has worse damage on sewer and water facilities. Given that all these repair and respondents are from different departments of St. Himark, decisions on which department to send can also be made.
1.3 Analysis of Location with the hardest hit In this analysis, shake intensity is removed as we are focusing on the damage done to the cities. Based on the average damage of all the damage reports, we can see that location 7 has the highest average damage. However when looked in location 7, the root cause of the high average damage comes from the damage on the power. On the other hand, looking at location 8, which has the next highest damage, damages are inflicted on almost all infrastructures and facilities. Although location 7 has highest damaged on its power, the situation is probably not as critical as locations with damages on its infrastructures and facilities which can results in loss of lives.	center

Task 2: Use visual analytics to show uncertainty in the data, compare the reliability of neighborhood reports and find out which neighborhoods are providing reliable reports.

Use visual analytics to show uncertainty in the data. Compare the reliability of neighborhood reports. Which neighborhoods are providing reliable reports? Provide a rationale for your response. Limit your response to 1000 words and 10 images. and 8 April 2020 In order to analyse the reliability of the report, a comparison with the earthquake shake map is done. Since the earthquake shake map on 6 April 2020 and 8 April 2020 are given, only damage reports in these 2 days will be looked into.

Insights	Visualization
2.1 Comparison of damage reports on 6 April 2020 Firstly, looking at the earthquake shake map on 6 April (on the right), it looks like the earthquake has not hit the cities in St. Himark. This is aligned with the damage reports (on the left) where damages are low which are probably due to the shaking even though it is indicated as "not felt" in the earthquake shake map.
2.2 Comparison of damage reports on 8 April 2020 In this analysis, shake intensity is removed as we are focusing on the damage done to the cities. Based on the average damage of all the damage reports, we can see that location 7 has the highest average damage. However when looked in location 7, the root cause of the high average damage comes from the damage on the power. On the other hand, looking at location 8, which has the next highest damage, damages are inflicted on almost all infrastructures and facilities. Although location 7 has highest damaged on its power, the situation is probably not as critical as locations with damages on its infrastructures and facilities which can results in loss of lives.	center

Task 3: Examine how the conditions, uncertainty in and key changes have changed over time

How do conditions change over time? How does uncertainty in change over time? Describe the key changes you see. Limit your response to 500 words and 8 images.
