Earthquakes can be very dangerous, if you are in the wrong place. They can make buildings fall down and set off landslides, as well as having many other deadly effects. An earthquake that occurs at the bottom of the sea can push water upwards and create massive waves called tsunamis.
Why earthquakes are so dangerous?
Earthquakes can trigger landslides and mudslides, especially in areas with water-soaked soils. Landslides may result in falling rocks and debris that collide with people, trees, animals, buildings and vehicles. They also can block roads and disrupt utility lines.
Why are some earthquakes more dangerous than others?
Why do earthquakes cause such devastation? The point underground where the force is created is called the focus. As the strength of the force varies, so do the scale of the earthquakes. This is why some earthquakes cause a lot more damage than others.
What is the most feared earthquake and why?
The most deadly earthquake in history was in Shaanxi, China in 1556. It’s estimated to have killed 830,000 people. This is more than twice that of the second most fatal: the recent Port-au-Prince earthquake in Haiti in 2010. It’s reported that 316,000 people died as a result.
What is the main danger during an earthquake?
These include ground shaking, landslides, liquefaction, and in some areas, tsunamis. These primary hazards often produce secondary hazards such as ruptured utility lines, hazardous spills, and fires. Buildings can crumble or collapse, trapping people inside and burying streets in rubble.
Can earthquakes destroy Earth?
Strong earthquakes can be extremely dangerous. The earth’s shaking may cause landslides or even rupture the surface of the ground. When saturated loose soils lose their stiffness and form, liquefaction occurs, and the ground collapses like a liquid.
Should you go outside during an earthquake Why?
But experts have long warned the public against leaving a building and heading outdoors during a quake. The safest place to be as the earth moves is inside, protected from potentially crushing debris, drooping power lines, falling trees or building extremities that could crumble.
Where is the safest place to be in an earthquake?
Stay Safe During an Earthquake
- DROP down onto your hands and knees before the earthquake knocks you down. …
- COVER your head and neck (and your entire body if possible) underneath a sturdy table or desk. …
- HOLD ON to your shelter (or to your head and neck) until the shaking stops.
Will I die in an earthquake?
Earthquakes account for the majority of deaths from a range of natural disasters which amounts to about 60,000 people a year worldwide – around 90 percent of which occur in developing countries (OECD, 2008). Most earthquake deaths are related to building collapse or damage.
What can make earthquakes worse?
The more energy in an earthquake, the more destructive it can be. Depth: Earthquakes can happen anywhere from at the surface to 700 kilometers below. In general, deeper earthquakes are less damaging because their energy dissipates before it reaches the surface.
What is the world’s worst earthquake?

What’s the longest earthquake recorded?
The very largest quake ever to be recorded was the Great Chilean Earthquake (Valdivia Earthquake) on 22 May 1960. At magnitude 9.5, it was about as large as an earthquake according to geophysical laws can be.
What would a 10.0 earthquake do?
A magnitude 10.0 quake could occur if the combined 3,000 km of faults from the Japan Trench to the Kuril-Kamchatka Trench move by 60 meters, Matsuzawa said. … A magnitude 10 quake would likely cause ground motions for up to an hour, with tsunami hitting while the shaking was still going on, according to the research.
What country has the most earthquakes?
For which country do we locate the most earthquakes? Japan. The whole country is in a very active seismic area, and they have the densest seismic network in the world, so they are able to record many earthquakes.
How can earthquakes affect humans?
Earthquakes usually cause severe damage to urban centres, resulting in the loss of life and damage to homes and other infrastructure. Although risks are normally associated with cities, the effects on the rural sector and farming communities can be devastating.
What are the 5 effects of earthquakes?
The effects from earthquakes include ground shaking, surface faulting, ground failure, and less commonly, tsunamis.
