Dashboard Overview
The interactive visualization can be accessed here:
For the best experience, adjust your screen resolution to 1366x768 and enable full screen on the browser. Adjust the dashboard so that all elements can be clearly visible without the need to scroll up/down.
A summary of the breakdown of the visualizations created for Question 1 is as shown below.
No. | Dashboard Name | Purpose |
---|---|---|
1 | Overview | Provide more information on the Mini-Challenge and the questions that will be addressed |
2 | Shake Map Analysis | Gain a better idea of the situation and see if the reports reveal the same key observations |
3 | Time Of Earthquake | Identify when the earthquake started and use the identified timeframe for further analysis |
4 | Hardest | Identify which neighbourhoods are hardest hit from the earthquake |
5 | Emergency Response Planning | Determine how the emergency response should change based on the reports made |
6 | Prioritization: Building, Medical, and Power Damages | Some cities are more affected than others and prioritizing the right cities based on the damage types is a very crucial step |
7 | Prioritization: Roads and Bridges, Sewer and Water Damages | Some cities are more affected than others and prioritizing the right cities based on the damage types is a very crucial step |
A summary of the breakdown of the visualizations created for Question 2 is as shown below.
No. | Dashboard Name | Purpose |
---|---|---|
1 | Reliability Of Reports #1: Damage Reports Over Time | Analyse reports made before the earthquake and delay in reports |
2 | Reliability Of Reports #2: Comparison Of Maximum Impact Scores Over Time | Observe the change in impact scores before, during and after the earthquake |
3 | Reliability Of Reports #3: Variation In Impact Scores | Explore the differences in the reported impact scores by citizens who live in the same region / within the neighbourhood |
4 | Damage Uncertainty | Observe the relationship between shake intensity and other damage types |
For Question 3, the insights will be derived from any of the charts mentioned above.
Throughout all the different dashboards, useful guides/tips are provided to help users navigate through the different filters and actions so that their analysis can be performed smoothly. The following interactivity elements are also used throughout all the dashboards to maintain consistency:

The following sections elaborate on the dashboard design and other interactivity techniques that are integrated into each of the individual dashboard.
Overview
Dashboard Design
Purpose / Description
The Overview is the landing page you will see when you open the workbook/link. This is considered the home page for this visualization. Icons are used to explain how crowdsourcing works and how it will used by the emergency response team. The visualization goals are also started here to give the user with an idea on what to expect from the dashboards.
Shake Map Analysis
Dashboard Design
Purpose / Description
Before we begin analysing the reports, we will first analyse the shake maps that were captured on 6 April and 8 April 2020. This is a crucial step since the shake maps will be used to check the reliability of the reports made by citizens through the Rumble app - Do the reports reveal the same key observations? The shake maps indicate the corresponding earthquakes' epicentres and how much shaking can be felt across the city. This is critical for emergency decision making. Insights gained from the shakemap are also displayed here.
Time Of Earthquake
Dashboard Design
Purpose / Description
The aim of the dashboard is to analyse the number of reports made by each neighbourhood throughout the entire period and identify the time of the earthquake. The charts are placed side by side to allow for easier analysis. The filter are consistently placed at the right side of the dashboard and the tips will help the user to explore the chart on their own. The line chart is used since the objective is to show the trend in reports made over time.

Hardest Hit Areas
Dashboard Design
Purpose / Description
The aim of the dashboard is to analyse the average shake intensity and the number of shake intensity reports made for each neighbourhood throughout the entire period. A heatmap is used to show the average shake intensity as it allows the user to quickly identify areas that are more affected from the earthquake. The gaps in the chart indicate that no reports (for all damage types) were made. Null impact scores are not filtered out in this chart. Therefore, if the user hover over the data points and the average shake intensity is empty, it means that the impact score is Null.
For the Shake Intensity By Impact Level chart, the purpose is to show the variation in impact levels reported and to identify cities that are hardest hit. There are 2 options to view this chart – Horizontal or Vertical. A grouped bar chart is used since it allows for easy comparison and identification of patterns and anomalies.

Emergency Response Planning
Dashboard Design
Purpose / Description
The emergency response can be determined by the mode of the damages. The blank map makes it easy for users to see the change in size of the circle marks which denotes the number of reports over time. The bigger the size, the greater the number of reports made by a specific neighbourhood. The mode chart is represented by the maximum number of reports made by impact score for each damage type and neighbourhood. It is better to use mode instead of average and maximum since they are prone to be affected by outliers. An area that is hardest hit may not always have a very high number of reports since there are other factors that could influence the number of reports like the size of the population in a neighbourhood.
Therefore, using the mode of the impact score seems to be a better option in assessing the extent of the damage. The overview table will also provide the emergency responders with a breakdown of the reports by impact scores if they prefer to look at the details. The maps would allow them to get the information they are looking for at a glance.

Prioritization - Maps (Building, Medical, Power)
Dashboard Design
Purpose / Description
The aim of the dashboard is to identify neighborhoods to prioritize based on the damage reports and shake maps. Having maps for each damage type will allow users to see an overview of the damages across types and the heatmap makes it easy to identify areas that require more immediate attention than others. The relevant information like maintenance work and building information is strategically placed below the chart so that the team can refer to it and take that into consideration when making critical decisions.
An assumption made is that the emergency response team comprise of different divisions and responders are specialized or trained to deal with a specific damage type. The Amenities filter can also come in handy when it comes to transporting the injured to the hospitals and the school can be turned into a temporary shelter if needed.

Prioritization - Roads and Bridges, Sewer and Water
Dashboard Design
The aim of the dashboard is to identify neighborhoods to prioritize based on the damage reports and shake maps. Having maps for each damage type will allow users to see an overview of the damages across types and the heatmap makes it easy to identify areas that require more immediate attention than others. The relevant information like maintenance information is strategically placed below the chart so that the team can refer to it and take that into consideration when making critical decisions.
Possible implications of maintainance work: Repair work in some roads will result in delays in traffic. This can also mean that rescue efforts may be affected.
