perhaps because of the depth of our core or central part of our world it emits a little heat into the holes and passages up or volcanoes and this is the cause of the volcanic eruption resulting in great damage to the land around it.

BOB DOIGHTY:In the twentieth century, scientists began to understand that the
Earth is a great, living -- and moving -- structure. Some experts say this
understanding is one of the most important revolutions in scientific thought.
The knowledge of the Earth’s constant motion is based on the work of scientists
who study the movement of the continents. This process is called plate tectonics.
Earthquakes and volcanic activity are a result of that process. Plate tectonics is
the area of science that explains why the Earth’s surface moves, and how those
changes cause earthquakes and volcanic activity.
FAITH LAPIDUS: Scientists say the surface of the Earth is cracked like a huge
eggshell. They call these pieces tectonic plates. As many as twenty of them cover
the Earth. The plates sometimes hit each other, and sometimes move away from
each other. Because some continents are above two plates, the continents move
when the plates do.
BOB DOUGHTY: The movement of tectonic plates can cause earthquakes and
volcanoes. Modern instruments show that about ninety percent of all earthquakes
happen along a few lines in several places around the Earth. These lines follow
underwater mountains, where hot liquid rock flows up from deep inside the Earth.
Sometimes, the melted rock comes out with a great burst of pressure. This forces
apart pieces of the Earth’s surface in a violent earthquake.
Some earthquakes take place at the edges of continents. Pressure increases as
two plates move against each other. When this happens, one plate moves past
the other, suddenly causing the Earth’s surface to split open.
FAITH LAPIDUS: One example of this pressure is found on the west coast of the
United States. One part of California is on what is known as the Pacific plate. The
other part of the state is on what is known as the North American plate.
Scientists say the Pacific plate is moving toward the northwest, while the North
American plate is moving toward the southeast. These two huge plates come
together at what is called a fault line. This line between the plates in California is
called the San Andreas Fault. It is along or near this fault line that most of
California’s earthquakes take place, as the two tectonic plates move in different
directions.
The city of Los Angeles is about fifty kilometers from the San Andreas Fault.
Many smaller fault lines can be found throughout the area around Los Angeles. A
major earthquake in nineteen ninety-four happened along one of these smaller
