Earthquakes are super deadly especially if you are in the wrong place. Like if you in a house surrounded by furniture than you have a likelihood of dying. There are 12,000 to 14,000 earthquakes a year. A 7.0 earthquake can be 10 to 30 minutes long but they are still very dangerous.Indonesia, Sri Lanka, India, and Thailand were hardest Earthquakes. With a magnitude of between 9.1 and 9.3, it is the second largest earthquake ever recorded on a seismograph. This earthquake had the longest duration of faulting ever observed, between 8.3 and 10 minutes. So if we can??t stop earthquakes then we can prevent our lives and also our houses.
Even before you start designing a construction which will be earthquake resistant, the first thing to consider is the soil quality which will be able to withstand the pressure of the earthquake. The soil should have good flexibility and capability. Look for soils which have coarse components like argillaceous sands, sandy gravels and consolidated soils. These soils are usually exposed to compact, hard and natural experiments and are great for earthquake resistant structures. Refrain from soils which are soft, sandy, clayey, loose as these are not appropriate for construction. Also add plastic soils in this list as they tend to lose their mechanical capacity and strength and become deformed after receiving water. As a result, they are in no way suitable for construction. Also refrain from steep slopes, dispersive clays and soils with organic fillings.
There is a thing called seismic invisibility cloak.Yes, you read it right. Invisibility cloaking can save you from getting squished like a tomato during an earthquake. Here's how. Earthquake spreads on terrain as waves that create the side to side movement on the surface making buildings sway back and forth. To prevent this movement, some engineers place 100 plastic rings in the foundation of a building which the work as a cloak and make the waves invisible. Not as cool as you expected, right? This technology has been tested for the last few years by several structural engineers abroad and only a handful of building have succeeded.
If you didn't know most skyscrapers are prone to earthquakes. This method is Pendulums for skyscrapers.The technique is really simple all you need to do is suspend a large ball of huge mass with steel cables in a fixed structure at the top of the building. So when the building starts to sway during earthquakes, the ball acts like a pendulum.The ball will sway side to side keeping the building stabilized. These pendulums are also known as tuned mass dampers because the pendulums are tuned to match with the buildings frequency.
In conclusion that is three of the things that can reduce the injuries and damage after earthquakes If you live where earthquakes are common then I suggest you use at least one for the safety of your family and house because your safety is important.
