The most important information for a geologist studying a prehistoric earthquake in the pictured trench is that the layers have been offset a measurable distance across a crack. This indicates that there was a fault movement during an earthquake which caused the layers to shift. The other information provided, such as the presence of sediment and soil layers and a vertical crack, may be useful for understanding the geological history of the area but are not specifically related to earthquake activity. The light colored sediment may indicate a change in environmental conditions or mineral content, but this alone does not provide significant information about an earthquake.
