On Sunday morning, a magnitude 5.1 earthquake struck along the North Carolina border.
The entire state was shaken by the North Carolina earthquake, from the Raleigh area to Charlotte to South Carolina. Many houses were shaken by the earthquake and citizens were terrified.
The Sunday earthquake was recorded as the largest in North Carolina after a 5.2 magnitude earthquake in Skyland, in County Comb in 1916.
Randy Baldwin (Earth Physicist) of the National Seismic Information Center in Colorado said the earthquake occurred at 8:07 a.m. near the town of Sparta on the border between North Carolina and Virginia.
“It felt like a big passing locomotive and a big wave coming down the bed,” Spartan Mayor Wes Brinegar told CNN. “There’s a big wave coming to lift you up… I’ve lived here my whole life and never felt like that.”
In the eastern United States, the recovery has been delayed as a hurricane has passed, and there are many places where citizens are without electricity.
There is a great inconvenience because we can not use essential household appliances for life and communication is not good.
However, this time, the earthquake is causing the anxiety of the citizens to increase.
The North Carolina earthquake is said to have caused no casualties, but hurricanes and earthquakes have occurred in the absence of a corona 19 confirmed increase.
According to the USGS, by 2 pm, the number of earthquake reports increased to 90,000, and spread to the wider southeastern region.
Randy Baldwin warned that there is a “high chance of an aftershock.” It can last for a week or two and generally decreases over time.
The USGS said that the probability of earthquakes with a magnitude of 3 or more is 58%, and the probability of earthquakes with a magnitude of 5 or more is 5%.
What caused the earthquake?
Earthquakes occur when two blocks of the Earth suddenly pass each other.
The area where slips occur is called a defect.
Earthquakes are earthquakes, or main earthquakes, precedence and aftershocks follow.
So before the main earthquake, a preliminary earthquake, or a mild earthquake, occurs; and a mild aftershock occurs after the main earthquake for several days or weeks.
What is the seismic response?
During the earthquake, you go under the table to protect your body and hold the table legs.
When the shaking stops, it blocks electricity and gas, opens the door and moves to the exit.
When you move out of the building, you use the stairs to move quickly. Elevators are prohibited.
Outside the building, you protect your head with your bag or hand, and you move around the building at a distance from the building.
We move to a large space, such as a playground or park, quickly to avoid falling objects. (Prohibition of car use)
Radio, you act on the announcement.
What is the seismic response method by place?
If you’re in the house: go under the table, protect yourself, shut off electricity and gas when the shaking stops, open the door, move out to the exit.
If you are outside the house : Protect your head with a bag or hand for falling objects, move away from the building to a large space such as a playground, a park,
If you’re in an elevator : Press the button on all floors to get off the first floor, then move to the stairs and go out.
If you’re in school: Get under your desk and grab your desk leg. When the shaking stops, keep order and move to the playground.
Department stores, if in the mart: Protect your body from objects falling from the shelves, move near stairs or columns, move out when the shaking stops
In theaters, stadiums, etc : Protect your head with bags and other things until the shaking stops. Move calmly as guided.
If you’re on a train : grab the handle or the post and avoid falling over; if the train stops, act according to the guide.
If you’re driving : Turn on the emergency lights and slowly slow down to pull over to the side of the road and move with the keys flowering as you listen to the radio’s information.
If in a mountain or sea: Move to safety, cautioning against landslides, cliff collapses; and move to higher ground when the tsunami cervical is announced off the coast.
We’ll have a family meeting against the earthquake.
Know how to cut gas and electricity through regular family meetings.
The place can evacuate including the wide space of surrounding etc. is known in advance.
Share how to contact your family in an emergency.
The method for doing the first aid is trained repetitively.
The emergency supplies is prepared and the storage place is shared in advance.
What are the Intensity and Magnitude?
Magnitude: The magnitude of energy the earthquake itself has, so, the magnitude is the same, no matter where the seismic wave is observed.
Expression: Examples of numerical representation to the first decimal point) scale 3.8
Intensity: The intensity of an earthquake felt in a place is expressed as a shaking of a person’s feeling or surrounding object or structure.
Therefore, even a large earthquake has a small impact from a very far distance, and the magnitude is reduced, and the magnitude varies depending on the ground conditions and building conditions even in the same area.
Expression: Examples of Romanization) Jindo IV
Intensity 1: A microscopic vibration appears that a person can hardly feel, but seismometers are detectable.
Intensity 2: The hanging stuff is shaking weakly and some feel it.
Intensity 3: You can feel it indoors, and there’s the same vibration as near trucks passing by.
Intensity 4: Stopped cars shake
Intensity 5: Almost everyone feels shaken, and bowls or windows are broken.
Intensity 6: Everyone feels an earthquake, heavy furniture could move or crack walls
Intensity 7: Everyone jumps out in surprise, drivers feel shaken too
Intensity 8: Windows fall from window frames; chimneys, columns, monuments and walls collapse.
Intensity 9: All buildings are damaged, cracks are cracked on the surface, and underground water pipes are destroyed.
Intensity 10: The ground cracks and the lanes are curved.
Intensity 11: The bridge collapses and a deep crack occurs on the surface.
Intensity 12: The object pops into the air, showing waves in the ground expression.
What are emergency supplies for earthquakes?
Water, canned, ramen, ointment, cold medicine, digestive agent, radio, flashlight and battery, emergency money, simple clothes, toilet paper, lighter
