earthquakes
Buildings that were retrofitted to withstand earthquakes or those built with seismic design features were more likely to survive the Kobe earthquake. On the other hand, older buildings or structures that were poorly constructed were more susceptible to damage or collapse. Additionally, the soil composition and proximity to the fault line also played a role in determining which buildings survived and which did not.
An earthquake that measures 7.0 on the Richter Scale will result in the following: Can cause serious damage over larger areas. Major damage in all structures, ground cracked, pipes broken, shift foundation.
A 5.1-magnitude earthquake is considered moderate. It can cause damage to buildings and infrastructure, especially in poorly constructed areas, and may be felt by people several miles away from the epicenter. Casualties and injuries are possible in densely populated areas.
According to the US Geological survey, the maximum intensity of the magnitude 9.5 Chilean earthquake of 1960 was rated as XI on the Modified Mercalli Intensity scale which are described as very disastrous or extreme events which are likely to cause significant damage to structures. Please see the related link for details.
It depends on the tornado and where it occurs. Weak tornadoes (EF0-EF1) which inflict minor to moderate damage typically cause a few thousand to a few hundred thousand dollars in damage. Stronger tornadoes (EF2-EF3) often have damage totals in the millions of dollars. Some of the worst tornadoes (typically EF4 or EF5) can have damage in the hundreds of millions or even billions of dollars. Some tornadoes stay in open fields and don't cause any damage.
there would be considerable damage in poorly built structures
Earthquake damage is typically caused by the combination of ground shaking, surface faulting, and ground failure (such as landslides, liquefaction, and tsunamis). The greatest amount of damage is usually seen in densely populated areas with poorly constructed buildings and inadequate infrastructure. The level of damage also depends on the intensity and duration of the shaking, as well as the proximity of the epicenter to populated areas.
The most serious earthquake damage usually occurs near the epicenter of the quake, where the intensity of shaking is greatest. Urban areas with dense populations and poorly constructed buildings are particularly vulnerable, as they can suffer significant structural failures. Additionally, areas built on soft soil or near fault lines may experience more severe damage due to increased ground shaking and liquefaction.
Earthquakes with a magnitude of 5 can cause minor structural damage to buildings, such as cracks in walls and foundations. They can also lead to objects falling off shelves, minor landslides, and disruptions to utilities like gas, water, and electricity. In highly populated areas, there may be injuries to people and damage to infrastructure.
Buildings near the epicenter may sustain less damage depending on their construction materials, design, and foundation. Structures made of flexible materials, designed to withstand earthquakes, or built on stable foundations are less likely to sustain damage than those made of rigid materials, poorly designed, or built on unstable ground.
The State of New York outlawed the dumbbell shaped tenement buildings in 1901. The New York State Tenement House Act of 1901 banned the poorly lit and poorly ventilated buildings.
The most damaging seismic waves capable of crumbling buildings are the surface waves, particularly Love waves and Rayleigh waves. These waves travel along the Earth's surface and have larger amplitudes and longer durations compared to other seismic waves, causing significant ground shaking. The intensity of the shaking can lead to structural failures, especially in poorly designed or older buildings.

The greatest damage during an earthquake typically occurs near the epicenter, where the seismic waves are the strongest. Areas with older, poorly constructed buildings or infrastructure are more prone to extensive damage. Additionally, regions with loose, water-saturated soil, like liquefaction-prone areas, can experience significant destruction.
As a result buildings were built anywhere, sewage and sanitation systems were poorly designed, and public became a problem.
