The most exciting phrase to hear in science, the one that heralds the most discoveries, is not "Eureka!" (I found it!) but "That's funny..." ~Isaac Asimov The universe is full of magical things patiently waiting for our wits to grow sharper. ~Eden Phillpotts, A Shadow Passes

EARTHQUAKE QUESTIONS 4. THE LARGEST EARTHQUAKE OF THE LAST 100 YEARS OCCURRED ALONG WHICH COAST? - ASIA - NORTH AMERICA - SOUTH AMERICA

EARTHQUAKE QUESTIONS 4. THE LARGEST EARTHQUAKE OF THE LAST 100 YEARS OCCURRED WHERE? - SOUTH AMERICA - ALONG THE COAST OF CHILE IN 1960 THIS WAS A 9.2 EARTHQUAKE. IT ALSO GENERATED A TSUNAMI THAT KILLED 61 PEOPLE IN HAWAII AND HUNDREDS IN JAPAN.

THE SUMATRA-ADAMAN EARTHQUAKE OF 26 DECEMBER 2004 KILLED OVER 230,000 PEOPLE IN 11 COUNTRIES – MOSTLY AS A RESULT OF THE TSUNAMIS THAT WERE GENERATED. MAGNITUDE 9.1 AND HAD A DURATION OFALMOST 10 MINUTES.

THE HAITI EARTHQUAKE (MAGNITUDE 7.0) KILLED OVER 300,000 PEOPLE AND LEFT OVER 1 MILLION HOMELESS – 12 JANUARY 2010.

EARTHQUAKES OCCUR ALONG PLATE BOUNDARIES WHEN THE PLATES STICK RATHER THAN SLIDING PAST EACH OTHER. PRESSURE BUILDS UP UNTIL IT IS STRONG ENOUGH TO OVERCOME THE FRICTION. WHEN IT SLIPS, AN EARTHQUAKE OCCURS. IN THE SAN FRANCISCO EARTHQUAKE OF 1906, IT WAS FOUND THAT ONE SIDE OF THE FAULT SLIPPED 21 FEET COMPARED TO THE OTHER SIDE OF THE FAULT.

WHERE DO EARTHQUAKES OCCUR? ALONG PLATE BOUNDARIES AND FAULT LINES

The Richter scale is a standard scale used to compare earthquakes. It is a logarithmic scale, meaning that the numbers on the scale measure factors of 10. So, for example, an earthquake that measures 4.0 on the Richter scale is 10 times larger than one that measures 3.0. On the Richter scale, anything below 2.0 is undetectable to a normal person and is called a microquake. Microquakes occur constantly. Moderate earthquakes measure less than 6.0 or so on the Richter scale. Earthquakes measuring more than 6.0 can cause significant damage. The maximum quake rating ever measured is about 9.2.
