Caused by a slip along the San Andreas Fault, the earthquake lasted approximately 15 seconds and measured 6.9 on the moment magnitude scale.The quake killed 67 people throughout northern California, injured 3,757 people and left more than 12,000 people homeless. The earthquake occurred during the warm up for the second game of the 1989 World Series, coincidentally featuring both of the Bay Area's Major League Baseball teams, the Oakland Athletics and the San Francisco Giants. This was the first major earthquake in America to be broadcast on live television. The epicenter of the quake was in Forest of Nisene Marks State Park, an unpopulated area in the Santa Cruz Mountains near Aptos and approximately 16 km northeast of Santa Cruz. The quake was named for the nearby Loma Prieta Peak which lies 8 km to the northeast.

Abridged from United States Earthquakes 1960, by H. Carroll Talley, Jr. and William K. Cloud. U.S. Department of Commerce, Coast and Geodectic Survey. Near coast of Chile. Magnitude 8.3. More than 2,000 killed, 3,000 injured and $550 million damage in Chile; seismic sea wave caused 56 deaths, $75 million damage in Hawaii; 138 deaths and $50 million damage in Japan; $500 thousand damage to west coast of the United States.
It was miles away from the capital called Port au Prince. The quake moved horizontally, the tectonics plates moved past one another, southwest of the capital which was densely populated. An associate coordinator, Michael Blanpied, of the Geological Survey’s Earthquake Hazards Program described the plates as grinding and crushing past one another. He also said the quake was a relatively shallow earthquake as it occurred 6 miles below the Earth’s surface and that this caused the populated areas to be shaken extremely strongly. Rene Preval, the president of Haiti, said to the Miami Herald that she would think that the death toll would be “unimaginable”.
Trevor Palmer 4/30/14 5th Period 1960 Chilean & Japanese Tsunami Natural disasters can happen at any moment, ranging from the most deadly to just minor natural disaster, but on this day in May of 1960 something happened that will never be forgotten. They say it was the largest earthquake that ever happened off the coast of Chile and because of that a tsunami happened also. According to the Natural Disaster Organization “the earthquake hit at 7:11 pm approximately 100 miles off the coast of Chile”. The shock of the earthquake had a large magnitude of at most 9.5, this goes without saying that there were warnings of this going to happen the day before. The deadly earthquake caused a large amount of damage and death in the country and in the pacific coastal areas.
At approximately 5:12 a.m. on Wednesday, April 18, 1906 the city of San Francisco was struck by a 7.9 magnitude earthquake! The main shock occurred offshore about 2 miles out. The earthquake happened along the San Andreas Fault line, and the shock was felt from Oregon to Los Angeles. The earthquake was extremely catastrophic which also resulted in fires. This earthquake is remembered as one of the most destructive natural disasters next to the Galveston hurricane of 1900, and hurricane Katrina of 2005.
8 H October 26, 2012 1886 Charleston Earthquake In Charleston August 31, 1886, a devastating earthquake shocked millions throughout the country. Not only was this earthquake reported in South Carolina, but in distant places such as Boston, Massachusetts, Milwaukee, Wisconsin, Chicago, Illinois, Cuba, Bermuda, and many more. Why so many places? The earthquake recorded a 7.4 on the Richter scale. This tells us that it’s a powerful earthquake, reaching and being felt by farther away places.
7. The most recent major eruption of Mount Saint Helens was May 18, 1980. The eruption was so large, the whole north face of the volcano slid away. I can tell it was the north face, because the compass points north and that is where the face slid away. This eruption was an explosive eruption.
Generally the Californian society’s capacity to cope is high and thus they are affected differently! On the other hand The Philippines consists of 7000 islands which are all sited on a destructive plate boundary where the dense oceanic plate is being subducted beneath the Eurasian plate. This generates deep focus earthquakes however with violent volcanic eruptions. For example during 1991 when Pinatubo erupted, around 700 people were killed and the damage was approximately
Japan is well known for being particularly amenable to subduction zone earthquakes, with huge pressures brought to bear by the sticking tectonic plate zones nearby it, and the slipping results in many earthquakes, some of them very big for instance the Tohoku earthquake. The Tohoku earthquake of March 11, 2011 also referred to as the Great East Japan Earthquake in Japan was one of the most powerful earthquakes that ever hit Japan and worldwide it’s recorded as the fifth most powerful earth quake. The earthquake triggered powerful tsunami waves that resulted into 15,883 deaths, 6,149injured and 2,652 people missing. The earthquake occurred in the north-western Pacific Ocean and lasted for approximately 6minutes. Initially, the earthquake was reported as having a 7.9magnitude (MW) and later it was raised to 8.8 then 8.9MW and finally to 9.0MW.
