• A strong tornado can generate wind speeds as high as 300 miles (500 kilometers) per hour.
WHICH NATURAL DISASTER CANNOT BE CAUSED BY SHIFTS IN TECTONIC PLATES? • Avalanche • Earthquake • Volcanic eruption • Hurricane
• While earthquakes, volcanic activity, and avalanches can be caused by shifts in tectonic plates, hurricanes originate over warm tropical oceans with low atmospheric pressure
• Chile • Unites States • Indonesia • Iran IN WHAT COUNTRY DID THE STRONGEST EARTHQUAKE ON RECORD OCCUR?
• A May 22, 1960, earthquake off the coast of Chile measured 9. 5 on the Richter scale. It triggered a tsunami that spread throughout the Pacific Ocean and caused about 2, 300 deaths.
• Earthquake • Hurricane • Tornado • Tsunami WHAT NATURAL PHENOMENON IS A HYPOCENTER ASSOCIATED WITH?
• Also called the “focus”, the hypocenter is where an earthquake rupture starts deep within the Earth. The Epicenter is the point on the Earth’s surface directly above the hypocenter.
• 1 in 7, 000 • 1 in 700, 000 • 1 in 7, 000 ON AVERAGE, WHAT ARE YOUR CHANCES OF BEING STRUCK BY LIGHTNING IN A GIVEN YEAR?
• The chance of a human being struck by lightning in a given year is roughly 1 in 700, 000. however, this is a simple average. Participating in certain outdoor activities, like golf and mountain climbing, or not taking precautions when a thunderstorm is near increase your risk.
WHICH OF THE FOLLOWING ISLANDS WAS COMPLETELY DESTROYED DURING AN 1893 HURRICANE? • Sumatra, Indonesia • Hog Island, New York • Rotuma, Polynesia • Bimini, Bahamas
• Destroyed in 1893 by a Category 2 hurricane, Hog Island is the only known example of the complete destruction of an entire island during a hurricane.
HOW OFTEN DOES LIGHTNING OCCUR WORLDWIDE? • 50 to 100 times per second • 25 to 50 times per second • 500 to 1, 000 times per day • 250 to 500 times per hour
• Lightning occurs on average 50 to 100 times per second worldwide. The greatest concentrations of lightning happen in parts of Central Africa, the Himalaya, and South America.
NATURAL DISASTERS FACT OR FICTION?
NO SUPERVOLCANO HAS ERUPTED IN HUMAN HISTORY. TRUE FALSE
• A supervolcano is a volcano that ejects more than 240 cubic miles (1, 000 cubic kilometers) of pumice and ash in a single explosion. No supervolcano has erupted in human history.
AVALANCHES CANNOT BE PREVENTED. TRUE FALSE
• In snowy areas avalanches can be predicted and prevented. Usually this involves actually triggering an avalanche, that is, making snow fall from high ground while no humans are around.
EUROPE HAS NEVER BEEN STRUCK BY A HURRICANE. TRUE FALSE
• Hurricanes form in the Atlantic westward to the Americas. powerful ones, however, can striking Europe. One such storm than 8, 000 English sailors in 1703. and move Particularly backtrack, killed more
TORNADOES OCCUR ONLY ON LOW-LYING GROUND. TRUE FALSE
• Tornadoes usually strike low-lying plains and valleys. However, they have been recorded as high as 11, 483 feet (3, 500 meters) in elevation.
TECTONIC PLATES MOVE VERY QUICKLY. TRUE FALSE
• On average, Earth's tectonic plates move at about the same rate as which fingernails grow, just a few inches (centimeters) a year.
MOST EARTHQUAKE ACTIVITY OCCURS CLOSE TO EARTH'S SURFACE. TRUE FALSE
• Most earthquakes occur within 43. 5 miles (70 kilometers) of Earth's surface. Very few take place at deeper levels.
THE MOST POWERFUL TORNADO IS AN F 1. TRUE FALSE
• Tornadoes are ranked from F 1 to F 5 on the Fujita scale of intensity. An F 1 storm is the mildest, with winds of less than 70 miles (112 kilometers) per hour; an F 5 can reach more than 300 miles (500 kilometers) per hour.
