Mini-Challenge 1: Crowdsourcing for Situational Awareness
Question 1
Question: 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?
Answer:
Based on the two shake maps provided and the shake intensity visualization from the report data, it is easy to identify that the northeast part of the city is hardest hit, namely location 3, 7, 4, 12. The average severity of these areas are above 80% percentile. So these neighborhoods should be prioritized for response
By changing the filter in the Damage Map Dashboard, highly damaged locations for each category can be found:
| Damage Type | Most damaged locations |
|---|---|
| Water & Sewer | location 3, 7, 8, 9 |
| Roads & Bridges | location 3, 8, 9, 14 |
| Power | location 3,7,10,11 |
| Medical | location 3,4,7,15 |
| Building | location 3,8,9,10 |
Apparently, Location 3 is the most damaged neighborhood of all, so it should be the first priority for rescue and other emergency response.
Besides, roads and bridges are very important for the rescue and recovery team to move around, the repairing of roads and bridges should be prioritized.
According to the number of report records for each location, location 3, 8, 9 are submitting most reports while location 7 is submitting least. From this we can interpret that at location 3, 8, 9, there are more people who need help. And although location 7 suffered from more intense shake, there are fewer people living there and submitting report, so location 3, 8, 9 should be paid more attention than location 7 given limited resources.
Question 2
Question: 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.
