Interesting Observations

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.

Insights

Summary	Detailed Description
Analysis of Shake Map	The source of the earthquake (epicentre) 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.
Determine the Time Of The Earthquake	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, 8AM. We can conclude that this is the time when the first earthquake started. We can use this information to determine the time period before the earthquake (pre-quake). 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. At 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. We can observe a spike in shake intensity reports again at 9 April starting from 3 PM although the earthquake is over.
Engineering	Engineering employees start entering into the building between 7am to 9am. At 9am, movements of the Engineering employees are mostly detected at floor 2. This might be due to their offices located at floor 2. Between 11am to 1pm, Engineering employees will take the elevators/stairs to floor 1 and go for their lunch break till around 2pm. Most Engineering employees will leave at around 5 or 6pm. However, Employee Clemencia, Penney, and Twana were often seen as the last few employees to leave the building at around 11pm.

For instance, Employee Varro and Employee Emile were often detected at Floor 1 during the night time starting at 12am. Also, at 2am, they will always be detected at Floor 1_Zone 6_Conf office_1030. And at 5am, only Varro will be detected at Floor 1_Zone 6_Conf office_1030. At around 9am, some employees from the facilities department will proceed to deli.

At 3pm-4pm, HR employees are not detected by any sensors in all floors. I speculate that they might have gone out for a tea break session. Lastly, at around 5pm, HR employees will start leaving the building.
