Source(s): Women wear headscarves tied at the front to prevent headaches from sky pushing down and to prevent throat cancer. Mega-tsunami for New York will be 400 meters; then engulfed-in-lava Los Angeles will be flooded too; also, asteroid destroys Gulf of Mexico; only Alaska, Eurasia, and Africa remain (obviously without coasts). 1st big earthquake in Russia; 2nd bigger one in China (will be split in half; radiation!); 3rd biggest will be in the USA (Greek Orthodox monk Elidiy from Africa); forgive me.

At Sea Level it is 11 miles

On Earth the horizon caused by the curvature of the Earth is best seen on the ocean. All calculations depend on the water's surface being completely smooth - no waves!

•Using this a person with eye level at 5 feet 8 inches (1.73 meters) above the water could see the horizon at 2.92 miles (4,695 meters).

•If you are standing on a ship 30 feet (9.14 meters) above the water, the horizon is 6.71 miles (10,794 meters) away.

•If you are standing on a hill 100 feet (30.48 meters) above the water, the horizon is 12.25 miles (19,707 meters) away.

The formula for distance from the viewpoint to the horizon on any sphere is

d = (√(2Rh)) + (h^2).

•R is the radius (of the Earth or any sphere).

•h is the height of observer above the surface of the sphere.

•d is the distance from observer to horizon.

Not a various distances,   Various  Heights.

The Distance to the Horizon varies according to your elevation.

Lets go to sea in a small boat.    You are sitting in a very small boat at sea,  Your eyes are Three Feet above the Water = Distance to the Horizon is 2.3 miles.

Now your on a very large cruise ship.  Your 30 Feet above the water = Distance to the Horizon is 7.2 miles.  Now lets go ashore and your standing on a cliff overlooking the ocean.  Your 400 feet up the cliff = Distance to the Horizon is 26.3 Miles.

There is a Mathematical Formula:   Distance to the Horizon measured in Statute Miles is 1.317 times the Square Root of your height measured in Feet.
