Prepare before an Earthquake
Always be ready with a plan for an earthquake when you are living at constant risk of its occurrence.
Make an emergency plan
Make an energy plan with first aid accessibility to quickly rescue your family members and yourself from a dangerous situation.
Science Of earthquakes
What is an earthquake?
Learn about the naturally occurring phenomenon, its measurement, time of occurrence, and the best ways to deal with it.
What causes earthquakes and where do they happen?
An earthquake can occur due to several reasons, including volcanic eruptions, geological faults, tectonic movements, and can also be man-made.
Why does the earth shake when there is an earthquake?
When the energy inside the earth’s crust radiates in all directions, it forms seismic waves that create the ripple. These seismic waves start to shake the earth as they move up.
How are earthquakes recorded?
There are many methods to record the earthquake. Learn how you can record and measure an earthquake at home.
How do scientists measure the size of earthquakes?
Learn about the labs and equipment of scientists used to measure and keep track of any tectonic activity on earth.
How can scientists tell where the earthquake happened?
The earthquake can only be predicted moments before it takes place. It can grow in intensity, but the smallest initial movements can be tracked at all times.
If an earthquake happens, protect yourself right away
Learn how to take the initiative and help others around to quickly find the nearest safety during an earthquake.
Stay Safe During an Earthquake
Drop on the ground and crawl to safety.
Find a solid cover to protect yourself.
Wait for the earthquake to pass and stay strong.
The tectonic plates divide the Earth's crust into distinct "plates" that are always slowly moving. Earthquakes are concentrated along these plate boundaries
Earthquake is a more common phenomenon than we realize. Having general awareness about earthquake will help people make quick decisions during the time of need.

For most of them, the New Madrid Seismic Zone is a relatively new term. In short, it is popularly called the NMSZ, and this zone is located in the various regions of California, including:
- Southeastern Missouri
- Northeastern Arkansas
- Western Tennessee
- Southern Illinois
- The Eastern Rocky mountains
These are the regions where the waves are extreme. This article will throw light on some facts about this region.
#1 This zone is sensitive to earthquakes and legend has it that these zones experience earthquakes simultaneous in all the regions, every 100 years. However, most of this seismic waves that pass-through the area are very sensitive to be detected by the humans and can only be caught by the seismic instruments.
#2 The faults on which the earthquake generally occurs, are buried between the layers of the earth and are almost 100-200 meters thick. They are buried under the river sediments which are popularly called alluvium. Most of the times, even with short tremors on the surfaces, this alluvium debris arise drastically form the surface. But over just matter of days, they’re again covered by new ones. Since they’re not the main topic of study for any of the scientists, their behaviour is not well-understood even to this day.
#3 The NMSZ is usually famous for a sequence of three major earthquakes with minutes of 7.0 or more massive of the two. These earthquakes occurred early in 1811 and 1812. However, apart from this, hundreds and thousands of moderate and mini earthquakes have also occurred until recent times, shaking the entire area for several months.
#4 The seismographs of the region provide the current recordings of the seismic waves that are produced in the region, and they’re also subjected to smaller earthquakes. Many universities around the region have also conducted studies to actually monitor the intensity of these earthquakes and their activity in the central US.
#5 The data of the earthquakes produced in this region is considered to study the magnitude of the seismic waves produced from the other mild and moderate earthquakes as well – some of which are lesser than 2.0 magnitude.
#6 The earthquakes that occur in the NMSZ regions are highly infrequent, especially the ones with larger intensity. Due to this, they are highly difficult to predict their occurrence and re-occurrence. This has made the study of this region highly intimidating, for the scientists over the years. The scientists are under constant research, and they’ve also made great strides in understanding their behaviour from the last 50 years.
#7 According to studies, another strong tide of an earthquake is going to stick the regions of Missouri Bootheel, Northeastern Arkansas and the areas of Tennessee in the upcoming years. This earth make is expected to have an intensity of 7.6 magnitudes and is believed to cause more significant damage than the ones it caused in California.
