       Earthquake Information
   An earthquake is when the ground shakes or
    spreads apart. Earthquakes can destroy buildings
    and cause many deaths. Earthquakes occur in the
    Virgin Islands, Northern and Southern California,
    Northern and Southern Alaska, and the Alaska
    Peninsula the most. Earthquakes occur in these
    areas the most because these areas are on tectonic
    plate boundaries since they are on the edges of
    tectonic plates. My area has a low risk of
    experiencing an earthquake because Indiana
    doesn’t have a lot of earthquake history and it isn’t
    on a tectonic plate boundary.
        How Earthquakes Effect
   Besides earthquakes volcanoes can do a lot
    of damage too. They both can destroy entire
    cities. Earthquakes and volcanoes can leave
    survivors homeless. Earthquakes affect
    people because sometimes people get
    trapped when buildings are destroyed. After
    an earthquake or volcano, it takes a lot of
    work to build new buildings and rescue

   Scientists can help you predict earthquakes by
    giving long-term predictions. You can also prepare
    for earthquakes by designing buildings that can
    withstand earthquakes. For example, houses need to
    have stronger walls and large buildings need to have
    base isolators to reduce how much they shake.
Magnitudes are determine by how powerful
 earthquakes are.
 Some earthquakes are very minor, but
 others can cause total destruction.
 A magnitude that is 1 more than another
 magnitude releases 32 times as much
 energy as the lower magnitude.
           Real-Time System
   The real-time system can be used to see
    where earthquakes are occurring all over the
    world. They show earthquakes everyday
    when they receive information. The real-
    time system sometimes predicts earthquakes
    in an area before they occur. Some real-time
    systems show the day, time, depth,
    magnitude of the earthquake, and where it
   Northern and Southern California, Northern
    and Southern Alaska, the Alaska Peninsula,
    and the Virgin Islands are all high-risk
    earthquake zones. High-risk earthquake
    zones are where earthquakes occur the
    most. There are three tectonic plate
    boundaries, convergent, transform, and
    divergent, boundaries. These boundaries
    can slide past each other, push against each

     Dear Mr. President,

What is causing earthquakes? Can you determine what areas are most prone to earthquakes? I am going to answer these questions
    and your other questions in this letter. The most recent earthquakes are occurring in the Virgin Islands, Northern and Southern
   California, and in Northern Alaska, and the Alaska Peninsula. Earthquakes are most likely to occur in certain locations because
   many faults are located along tectonic plate boundaries. Faults are fractures where blocks of rock past each other. Areas where
                                   earthquakes occur the most are high-risk earthquake zones.
                            You can determine what parts of the world are most prone to earthquakes because
The edges of tectonic plates scrape past each other. The Virgin Islands, Northern and Southern California, Northern Alaska, and the
  Alaska Peninsula are all on the edges of tectonic plates. This is why these areas are high- risk earthquake zones. These high-risk
 earthquake zones are located on tectonic plate boundaries, which are in the lithosphere. The lithosphere is a layer of the earth that
                                                 has many tectonic plates.
  Earthquakes and volcanoes do have a relationship. The relationship is that tectonic plates can cause earthquakes and volcanoes;
  volcanoes erupt because divergent plate boundaries spread apart and the magma from the mantle, a layer of the earth, rises up.
Divergent boundaries are also called spreading centers. Plates cause earthquakes when they collide together. Tectonic plates are all
      over the earth. Earthquakes occur all over the earth.
                                                         In an earthquake, the ground shakes because of the movement of large blocks
 of rock along a fault. Stress is released and causes earthquakes. Stress is the force that is exerted when an object pull on, presses
   on, or pushes against another object. Besides divergent boundaries, the other two tectonic plate boundaries are convergent and
       transform boundaries. Transform boundaries slide past each other and convergent boundaries push against each other.

 Earthquake Preparedness
A base isolator is placed in the middle of a
building and absorbs the ground’s motion to
make the building shake more smoothly,and
gently. Base isolators are made out of
flexible materials.
