Earthquakes, This Morning

Project #1700 on iSENSEProject.org

        The United States Geological Survey is constantly updating earthquake activity, from around the world, as it occurs.  The data for this iSENSE project was captured at 9:12 AM EST on November 21, 2015, from http://earthquake.usgs.gov/earthquakes/map/.

        According to Scholastic.com, the following is "an approximate and basic description of what happens when earthquakes of different strengths strike. You’ll notice that the higher the number gets, the worse the damage becomes.

        9.0 and above — Causes complete devastation and large-scale loss of life.

        8.0 — Very few buildings stay up. Bridges fall down. Underground pipes         burst. Railroad rails bend. Large rocks move. Smaller objects are tossed into         the air. Some objects are swallowed up by the earth.

        7.0 — It is hard to keep your balance. The ground cracks. Roads shake. Weak         buildings fall down. Other buildings are badly damaged.

        6.0 — Pictures can fall off walls. Furniture moves. In some buildings, walls         may crack.

        5.0 — If you are in a car, it may rock. Glasses and dishes may rattle.         Windows may break.

        4.0 — Buildings shake a little. It feels like a truck is passing by your house.

        3.0 — You may notice this quake if you are sitting still, or upstairs in a house.         A hanging object, like a model airplane, may swing.

        2.0 — Trees sway. Small ponds ripple. Doors swing slowly. But you can't tell         that an earthquake is to blame.

        1.0 — Earthquakes this small happen below ground. You can't feel them."
