We will analyze the data for the Pre-Earthquake Period (before 8 April). The filter is used to focus on this data. There is a spike in the number of reports on 6 April, 4 PM. We can see that Old Town, Scenic Vista and Broadview made a high number of reports at this timing across all damage types. Note that impact scores that are Null are not filtered out in this analysis.

With reference to the shake map on 6 April, the shaking intensity was ‘Not Felt’. We will focus on this timing 6 April, 4 PM to 6 PM for this analysis. Since the shaking is Not Felt, we should expect less damage during this time period. We can expect some reports coming from the 3 neighbourhoods closest to the epicenter which is Old Town, Safe Town, and Cheddar Ford but the impact level shouldn’t be high.

The average shake intensity for Safe Town was 2. The damage type filter for the mode chart is set to Shake Intensity. Safe Town was the only town with a mode of Weak from 4 PM to 6PM. At 7 PM, the mode changed back to Not Felt Since it is close to the source of the earthquake, it is acceptable and not an anomaly. The citizens might have overestimated the intensity of the shaking.

Another possibility of why there is a surge of reports could be due to maintenance work. For example, we will focus on Roads and Bridges damages. There is maintenance work going on at Cheddarford which will result in delays. There is also more than 1 mode in the chart for Cheddarford and this is on 6 April, 6 PM which is 2 hours after the spike in reports.

Summary Detailed Description
Surge of reports made before the earthquake on 6 April, 4 PM

We will analyze the data for the Pre-Earthquake Period (before 8 April). The filter is used to focus on this data. There is a spike in the number of reports on 6 April, 4 PM. We can see that Old Town, Scenic Vista and Broadview made a high number of reports at this timing across all damage types. Note that impact scores that are Null are not filtered out in this analysis.
