1) Would earthquakes of similar magnitudes in different populated regions of the Earth cause approximately the same levels of damage? In your discussions, consider both geologic and human-induced factors. The amount of damage caused by an Earthquake does not solely depend on the magnitude of the Earthquake. Factors such as population, geographic location, soil type, and the type of building material commonly used for construction in a region determine the extent of damage caused. If an Earthquake strikes a densely populated region, then life loss and property damage will be high. If an Earthquake of a similar or even higher magnitude strikes a region with a relatively low population, then life loss and property damage will be lower. The 6.4 Richter scale Earthquake (1993) in the State of Maharashtra, India and the 8.3 Richter scale Earthquake (2006) in Kuril Islands, Japan are examples that come to mind. With stone houses and a population of over 2 million, the Earthquake in Latur left nearly 8,000 people dead and brought as many as 30,000 houses to the ground. In contrast, Kuril Islands, with a population of just 17,000 and better disaster preparedness mechanisms, was able to get away with no loss of human life ,despite the fact that the Earthquake was much higher in magnitude when compared to that of Latur.

2) How are faults, foci (plural of focus), and epicenters related? Faults that are experiencing no active creep (relatively consistent yet minor movements) may be considered “safe.” Rebut or defend this statement with what you have learned so far about faults. The points in the lithosphere of Earth where fracturing originates are called foci. In other words, foci are the points at which energy-release takes place. Foci are also termed as hypocenters. Large fractures inside the Earth’s crust are called faults. Typically, news reports talk about epicenters...
