Study Figure 3, which displays data comparing two contrasting earthquake events.
| Date of earthquake | Region affected | Magnitude | Focal depth (km) | Short-term impact and consequences |
|---|---|---|---|---|
| 12 January 2010 | Port-au-Prince, Haiti | 7.0 | 13 | Over 220,000 deaths; collapse of poorly constructed buildings; key infrastructure destroyed |
| 25 April 2015 | Gorkha, Nepal | 7.8 | 15 | Approximately 9,000 deaths; triggered major avalanches on Mount Everest; rural villages isolated by landslides |
