Why in the event of an earthquake, most of what collapses are buildings while not trees?
Due to several factors, buildings are more likely to collapse than trees during an earthquake.
Structural design: Buildings are designed to satisfy specific structural codes and standards to withstand a variety of forces, including seismic activity. Nevertheless, trees have evolved to be flexible and resistant to natural forces such as wind, but they are not designed to withstand earthquakes.
Material composition: Typically, buildings are constructed with rigid materials, such as concrete and steel, which can be susceptible to earthquake-induced ground motion and movement. Trees, on the other hand, are composed of organic materials that are flexible and enable them to sway and bend in response to wind or other external forces.
Height and weight: Buildings are frequently taller and heavier than trees, making them more susceptible to the intense ground swaying during an earthquake. The lateral forces exerted on lofty structures can result in structural failure or deterioration, leading to their eventual collapse. Due to their lighter weight and greater flexibility, trees are less likely to suffer calamitous failure during an earthquake.
Foundation and anchoring: The purpose of a building’s foundation is to evenly distribute the structure’s weight and forces into the earth. During an earthquake, the building’s stability may be compromised if its substructure is improperly designed or constructed or if the soil conditions are poor. In contrast, trees have anchoring root systems that enable them to withstand some degree of ground movement.
Human influence: Poor construction practices, insufficient maintenance, and noncompliance with seismic codes frequently expose human-made structures to additional dangers. These factors can contribute to the increased earthquake vulnerability of structures.
In conclusion, during an earthquake, trees may not fall as frequently as buildings, but they can still be damaged or uprooted depending on the intensity and duration of the seismic activity.
