Earthquakes causes death of organisms despite the numbers present in the population. Hence it is an density independent factor.
The impact of the earthquake is the same even if the population is 100 or 1000.
It also does not depend on whether the organisms possess traits that aid in their survival.

the effect of human disturbance on animal populations is
a large dense,population
Crowding, disease, and competition are all density-dependent limiting factors EXCEPT, seasonal cycles. Seasonal cycles are NOT a density- dependent limiting factor.
Parasites can limit the growth of a population. They take nourishment from their hosts, often weakening them and causing disease or death. As the population of parasites grow, the population of their hosts tend to decrease.
density independent limiting factor
A density dependent factor is a limiting factor that depends on population size. A Density-independent limiting factor affects all populations in similar ways, regardless of the population size. Its in my Biology book.
A population size decrease is the usual response in the population size of many species to a density-independent limiting factor. Not enough food is an example of a limiting factor.

Density-independent limiting factors are factors that do not rely on the population and are aspects of an environment that limit its growth like hurricanes, fires, and deforestation.

Density- independent factors :D
Density-dependent limiting factor: A limiting factor whose effects depend on the size of the population depend on population density. The less dense the population, the less severe the effect of the limiting factor. Examples: Predation and disease Density-independent limiting factor: A limiting factor that has the same effect on a population regardless of its population density. Examples: Natural disasters and climate
The usual response in the population size of many species in regard to a density-independent limiting factor is for the population to decrease in size. Floods, wildfires, and droughts are examples of density-independent limiting factors.
