What is the most dangerous type of earthquake?
S waves are more dangerous than P waves because they have greater amplitude and produce vertical and horizontal motion of the ground surface.
The slowest waves, surface waves, arrive last.
They travel only along the surface of the Earth.
There are two types of surface waves: Love and Rayleigh waves..
What state has never had an earthquake?
Is there any place in the world that doesn’t have earthquakes? Florida and North Dakota are the states with the fewest earthquakes.
What are the 5 largest earthquakes ever recorded?

What does being in an earthquake feel like?
The shaking will feel violent and it will be difficult to stand up. The contents of your house will be a mess. A large earthquake far away will feel like a gentle bump followed several seconds later by stronger rolling shaking that may feel like sharp shaking for a little while.
How far away can you feel a 9.0 earthquake?
In a place with complex geology, every rock contact scatters and absorbs seismic energy, so that far away you’d probably feel it but not see damage or casualties. In the U.S. Midcontinent, with layer-cake geology that makes efficient wave guides, a 9.0 event would probably produce appreciable damage 565 miles away.
What is the atomic bomb equivalent to a 8.0 earthquake?
A magnitude 4.0 earthquake is only equivalent to about 6 tons of TNT explosives, but because the Richter scale is a base-10 logarithmic scale, the amount of energy released increases quickly: A magnitude 5.0 earthquake is about 200 tons of TNT, magnitude 6.0 is 6,270 tons, 7.0 is 199,000 tons, 8.0 is 6,270,000 tons, …
What is the difference between a 7.0 and 8.0 earthquake?
Essentially, each successive magnitude is 33 times larger than the last. That means a magnitude-8.0 earthquake is 33 times stronger than a 7.0, and a magnitude-9.0 earthquake is 1,089 (33 x 33) times more powerful than a 7.0 — the energy ramps up fast.
Can you feel a 3 earthquake?
The magnitude, location, and depth of an earthquake, and overlying soil conditions determine how widely and strongly any particular event can be felt. Typically, people report feeling earthquakes larger than about magnitude 3.0.
How bad is a 8.0 earthquake?
Intensity 8: Severe — Damage slight in specially designed structures; considerable damage in ordinary substantial buildings with partial collapse. Damage great in poorly built structures.
Has there ever been an 8.0 earthquake?
After the development of the Richter scale in the 1930s, scientists theorized the Shaanxi earthquake was probably between a 8.0 to 8.3 in magnitude—not the strongest one ever recorded, but certainly significant. … That quake created a tsunami, which together killed an estimated 5,700 people.
Can San Andreas really happen?
No. Magnitude 9 earthquakes only occur on subduction zones. As stated above, there hasn’t been an active subduction zone under San Francisco or Los Angeles for millions of years. … However, earthquake intensity along the modern-day San Andreas fault maxes out at approximately 8.3 (The Hollywood Reporter).
What is the longest earthquake ever recorded?
2004 Sumatra quake2004 Sumatra quake was longest ever recorded. According to new information about the earthquake of December 26, 2004, it was the longest-lasting earthquake ever recorded. “Normally, a small earthquake might last less than a second; a moderate sized earthquake might last a few seconds.
How bad is a 7.7 earthquake?
A major earthquake registers between 7 and 7.9 on the Richter scale. There are about 20 a year worldwide and they cause very serious damage.
How strong is an 8.0 earthquake?
MagnitudeEarthquake EffectsEstimated Number Each Year6.1 to 6.9May cause a lot of damage in very populated areas.1007.0 to 7.9Major earthquake. Serious damage.208.0 or greaterGreat earthquake. Can totally destroy communities near the epicenter.One every 5 to 10 years3 more rows
Is a 10.0 earthquake possible?
No, earthquakes of magnitude 10 or larger cannot happen. The magnitude of an earthquake is related to the length of the fault on which it occurs. … No fault long enough to generate a magnitude 10 earthquake is known to exist, and if it did, it would extend around most of the planet.
