1. Using the Internet, compare and contrast the 2010 Haiti earthquake with the 2011 Japan earthquake. Include magnitude, type of plate boundary, and extent of destruction in your comparison.
The earthquake in Japan was caused by the subduction of the Pacific Oceanic plate (SIMA) under the North American continental plate (SIAL). This created a 9.0 earthquake on the Richter Scale. The sudden release of the
million people were left without water and/or electricity. It caused $300 billion worth of damage was done and ceased car manufacturing all over the world. The earthquake in Haiti was caused by a conservative (strike slip/transform) fault. Stress and tension on this fault had been built up over 240 years. The release of all the stress and tension caused a 7.0 earthquake on the Richter Scale. It caused 230,000 deaths, 300,000 people were injured , 1000 deaths from cholera and 1 million people left homeless. 90% of the buildings near the epicenter were destroyed and 230,000 homes were destroyed.

2. Speculate about some of the possible consequences that a great and prolonged increase in volcanic activity might have on each of the Earth's four spheres.
Volcanic eruptions can have lasting effects on the Earth's four spheres. It can affect the atmosphere by the ash that is released can pollute the air, it can cause breathing problems for people and can even block the sunlight. It can affect the hydrosphere by polluting the ocean and increasing the temperature of the ocean. It can affect the biosphere by killing plants and animals. It can affect the growth of vegetation. It can affect the lithosphere by setting off earthquakes and tsunamis.
3. Use the USGS Earthquake data website to find the largest earthquake
ever in Louisiana; please give the location and magnitude of the earthquake.
The largest earthquake in Louisiana occurred in Donaldsonville on October 19,1930, and had a magnitude of 4.2 on the Richter Scale
