US East Coast was hit by a 5.8-magnitude earth quake at 1:51 p.m. Eastern Time, Tuesday.
The epicenter was 5 miles (8 kilometers) from Mineral, Virginia, and 84 miles (135 kilometers) away from Washington, D.C.
People ran out of their houses, tall buildings and offices.
Parts of the White House, Capitol and Pentagon were evacuated.
Some people did not know that was an earth quake and thought that it was an explosion, a bomb or a terrorist attack on their buildings.
The quake was felt as far north as Toronto, as far west as Indiana and Kentucky and as far south as Atlanta and Savannah, Ga.

Plate tectonics is a scientific theory which describes the large scale motions of Earth’s lithosphere. The theory builds on the older concepts of continental drift, developed during the first decades of the 20th century, and was accepted by the majority of the geoscientific community when the concepts of seafloor spreading were developed in the late 1950s and early 1960s. The lithosphere is broken up into what are called tectonic plates. In the case of the Earth, there are currently seven or eight major (depending on how they are defined) and many minor plates. The lithospheric plates ride on the asthenosphere. These plates move in relation to one another at one of three types of plate boundaries: convergent, or collisional boundaries; divergent boundaries, also called spreading centers; and conservative transform boundaries. Earthquakes, volcanic activity, mountain-building, and oceanic trench formation occur along these plate boundaries. The lateral relative movement of the plates varies, though it is typically 0–100 mm annually.

Dear Mr. Micheal H. Miller,
Thank you for the information.
I wish I can have a book that explains about earthquakes for kids with illustrations.
I have a few books about volcano.
