Earthquakes can cause a range of damage to the built environment, including structural damage to buildings, bridges, and roads, as well as non-structural damage like broken windows, damage to utilities, and landslides. The severity of the damage depends on factors like the magnitude of the earthquake, the proximity to the epicenter, and the quality of construction.
A building built on loose soil and rock is more susceptible to shaking and settling during an earthquake. The loose soil can amplify the shaking, leading to more severe structural damage. The building may also experience uneven settlement, causing potential structural failure.
Several factors determine the structural damage from an earthquake including, the proximity to active earthquake faults; the building construction (type of building, foundation, materials used, and quality of workmanship); the local site conditions (type and condition of soil, slope of the land, and fill material); and the geologic structure of the earth beneath the structure.
If you mean damage to the surrounding are then it all depends on how built up the area is. Most damage is caused by structural collapse so more built up areas will see a higher amount of damage than a less built up, more rural area. If you mean damage to the earths crust itself then you need to look at what type of earthquake it was and the location of the epicentre (the point of origin)
Building construction plays a significant role in determining the level of damage caused by earthquakes. Structures built with seismic design principles and materials that can absorb energy have a better chance of withstanding the shaking during an earthquake. In contrast, buildings that are not constructed to withstand seismic forces are more likely to sustain damage or collapse during an earthquake.

An earthquake can cause significant damage to the built environment, including structural failures of buildings, bridges, and roads due to ground shaking. This may lead to collapses, cracks, and displacements that compromise safety and usability. Additionally, secondary effects such as landslides, liquefaction, and fires can further exacerbate the destruction and hinder recovery efforts. Overall, the impact can result in substantial economic losses and displacement of communities.
Buildings built on soil sink due to settling after an earthquake
A house built on a soil river bank is likely to experience more damage during an earthquake compared to a house built on a solid rock ledge. This is because soil can amplify seismic waves and is more prone to liquefaction, which can lead to ground instability and structural failure. In contrast, solid rock provides a stable foundation that is less susceptible to shaking and ground movement, offering better support during seismic events.
The Marina District of San Francisco is built on landfill, which can amplify the shaking during an earthquake. Additionally, the soil in the Marina is prone to liquefaction, where the ground acts like a liquid during strong shaking, causing buildings to sink or tilt. These factors make the Marina District more vulnerable to earthquake damage compared to surrounding areas built on more stable ground.

there would be considerable damage in poorly built structures
Earthquake shock absorbers do exactly what they say on the tin, they absorb some of the energy generated by an earthquake, in order to prevent structural damage. Most tall building in San Francisco are built on the shock absorbers, so that they can still stand after an earthquake
Because they built wooden frame houses to withstand the earthquake, funnily enough, fire often comes with earthquakes.....
