- Epicenter Location: (latitude: 38.43°S, longitude: 74.90° W)
- Date & Time: 2011/09/03 16:20:41 Duration: N/A
- Depth to hypocenter: 12
- Magnitude: MS =; N/A MW = N/A
- Maximum Modified Mercalli Intensity: MMMI= N/A
Felt area: 82,500km2.
- Fault Name:
Rupture is often a process common in any earthquake (Bolt, 2004). The earthquake’s rupture process involved in the earthquake was rather sophisticated covering an approximated 316km extending to a depth of up to 12 m. The earthquake paralleled the coastline affecting an area of approximately 82,500km2.
- Plate Tectonic Setting:
Earthquakes often impact on the setting of plate tectonics (Abbott, 2004). There was a continuous crustal deformation linked with collision of the ridge as well as an oblique convergence of the Nazca tectonic plate with the South America’s continental block in the region of Central Chile. This resulted into substantial deformation as well as accumulation of strain which resulted into the 5.8 magnitude earthquake.
- Damage Details:
The quake did not cause deaths and property destruction despite the fact that its impact widespread felt on the coastal towns, as well as villages located in South Central Chile. The impact was also felt in Juan Fernandez Islands. Generally, the impact was not severe.
- Impact on culture, economy, & society:
An earthquake of magnitude 5.8 is considered moderate (Kobayashi, 2011). Considering its little impact and the fact in most areas it had no substantial effect, the earthquake had literally no effect on the culture, economy, as well as the overall society lifestyle except for some level of fear about possible recurrence of stronger quakes in the future.
