man-made structures were made by humans, but natural structures made itself.
The area of the United States that is the most seismically active is Alaska. After that the states that follow are California, Hawaii, Nevada, Washington, Idaho, Wyoming, Montana, Utah, and Oregon.
Structures can be made seismic safe through practices such as using flexible materials, designing buildings to withstand lateral forces, incorporating base isolation systems, strengthening connections between structural elements, and adhering to seismic building codes and regulations. These measures reduce the risk of damage and collapse during earthquakes.
acid rain destroys man made structures
Structures built by people or machinery are commonly referred to as "man-made structures" or "human-made structures." These can include a wide range of constructions such as buildings, bridges, roads, and dams. They are designed to serve specific functions and often reflect the engineering and architectural practices of their time.
The clearest indication that a community is seismically safe is if it has strict building codes and regulations that require structures to be built to withstand earthquakes. Additionally, if the community has conducted earthquake drills and preparedness campaigns to educate residents on what to do in the event of an earthquake, it shows a commitment to safety. Regular maintenance and retrofitting of infrastructure also contribute to seismic safety.
Disaster (natural)
Earthquake hazard maps say the seismicity of your State is low.
Yes, steel buildings need to be seismically upgraded but not very often.
Seismically resilient. This means that the building is designed to withstand the force and shaking of an earthquake, reducing the risk of damage and collapse. Various design features such as flexible structures, dampers, and bracing can contribute to the building's ability to resist seismic forces.
Rotifers are made of what structures
man-made structures were made by humans, but natural structures made itself.
Man made solid structures are structures that humans have built. Examples of man made solid structures are dams, brick walls and concrete and cement blocks.

Underground storm shelters or safe rooms are the most resistant structures during a tornado. These are built to withstand high winds and flying debris, providing a safe haven for occupants during a tornado.
It should be stored in safe storage in sparsely inhabited, seismically quiet areas. But, here kicks in NIMBY (Not In My Back Yard). See about Yucca mountain nuclear waste storage.
