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? Limit your response to 1000 words and 10 images.

The source of the earthquake (epicenter) appears to be located near the 12th of July Bridge and Himark Bridge on 6 April 2020. The shaking is weak. However, the shaking got stronger on 8 April and more cities were affected by the earthquake. From the shake map, we can see that the following cities are more likely to be greatly affected by the earthquake. Cities sorted by perceived damage: Old Town, Safe Town, Cheddarford, Pepper Mill, Wilson Forest, Easton, East Parton, West Parton, and Terrapin Springs. | |
The damage type filter is set to Shake Intensity for this analysis. From the Shake Intensity Reports By Neighbourhood chart, we can see that citizens from Old Town, Safe Town, Wilson Forest, Terrapin Springs, Pepper Mill, Cheddarford, Easton, East Parton, and West Parton made a high number of reports starting from 8 April, 8 AM. We can conclude that this is the time when the first earthquake started. Do note that records, where the impact score is empty, are filtered out. From the Shake Intensity Reports By Day/Hour line chart, we can see that 6939 shake intensity reports were made at 8 AM with Old Town making 31.56% of the total reports. On 9 April, 12,998 reports were made with Scenic Vista taking over the top spot and comprise of 14.80% of the total number of reports at that time. The number of shake intensity reports start to drop rapidly from 9 AM till about 6 PM on 8 April. The earthquake most likely ended at around 11 AM to 12 PM. We can observe a spike in shake intensity reports again on 9 April starting from 3 PM although the earthquake is over. We will investigate this further later on. | |
The hardest hit areas appear to be Old Town, Safe Town, Pepper Mill and Wilson Forest. This is supported by the shake map analysis since the neighbourhoods are located near to the epicentre of the earthquake and we can expect these neighbourhoods to be more affected by the earthquake. We can also identify anomalies in the data for Old Town and Wilson Forest. For Old Town, the neighbourhood is most likely to be greatly affected by the earthquake due to its close proximity to the epicentre, but no reports were made 1 to 2 hours after the earthquake on 8 April, 8 AM. A possible reason was that the earthquake resulted in a power outage and the citizens were unable to report the damages. As for Wilson Forest, the power outage situation appears to be worse since reports were made at the start of the earthquake on 8 April, 8 AM. Before the earthquake, no reports were made except for 6 April, 2 PM. (The other data points before the earthquake have Null shake intensity impact scores) For the Shake Intensity By Impact Level chart, we can see that Old Town, Safe Town and Pepper Mill are consistently the top 3 cities with the highest number of reports with an impact level of strong, very strong and severe on 8 April. This is supported by the average shake intensity chart with the 3 cities having a high average shake intensity score as compared to the other cities. | |
From the shake intensity charts, we can deduce that the following cities need more help from 8 April, 8 AM to 11 AM: Old Town, Safe Town, Pepper Mill, and Wilson Forest. The number of reports made by neighborhood chart also shows that areas that are hardest hit may not always have a high number of reports. Therefore, using the mode of the impact score seems to be a better option in assessing the extent of the damage instead of solely using the number of records in our analysis. | |
