Explanation of tsunamis would be interesting. More specific the tsunami alert system of the Pacific ocean involving mainly USA and Japan.

Depends what you mean by "the 10 most recent earthquakes".  Many tiny earthquakes have occured all over the earth since I started typing this answer.  Do you want the 10 most recent measurable earthquakes in a particular area (around your city, say)?  Or the 10 most recent large damaging earthquakes?\n\nhttp://quake.usgs.gov/recenteqs/index.html has a map of the most recent quakes in my part of the world; http://quake.usgs.gov/recenteqs/Quakes/quakes0.html lists them, something like 260 in the last week.\n\nhttp://earthquake.usgs.gov/eqcenter/recenteqsww/Quakes/quakes_all.php lists all quakes > magnitude 2.5 in the US, or > magnitude 4.0 in the whole world in the last week  The list shows quakes over magnitude 6.0 (big ones!) in red; at the moment it shows 8 of them in the last week.  http://gldss7.cr.usgs.gov/neis/qed/qed.html has a similar list, going back about a month, along with a map.

Since you're looking for earthquake learning experience not found in books, I recommend Virtual Earthquake, an interactive Web-based activity site.

These links provide earthquake info to the countries that border the Nazca Plate.\n\nhttp://earthquake.usgs.gov/regional/world.php?regionID=8&region=Chile\nhttp://earthquake.usgs.gov/regional/world.php?regionID=18&region=Peru\nhttp://earthquake.usgs.gov/regional/world.php?regionID=72&region=Ecuador\n\nThis link gives you access to a database which you can select specific time periods and regions.  Selecting South America and August through September produces a huge list.  You can then cross reference that to the countries.\n\nhttp://neic.usgs.gov/neis/epic/epic_global.html

Go to www.usgs.gov.  It's a great site that gives you all sorts of information about earthquaktes, faultlines, etc. I'm not sure if you can view all of North America, but as there are so many faultlines, it may be best to view it in smaller areas.  Good luck and enjoy exploring!

Are Earthquakes Really on the Increase?\n\nWe continue to be asked by many people throughout the world if earthquakes are on the increase. Although it may seem that we are having more earthquakes, earthquakes of magnitude 7.0 or greater have remained fairly constant. \n\nA partial explanation may lie in the fact that in the last twenty years, we have definitely had an increase in the number of earthquakes we have been able to locate each year. This is because of the tremendous increase in the number of seismograph stations in the world and the many improvements in global communications. In 1931, there were about 350 stations operating in the world; today, there are more that 8,000 stations and the data now comes in rapidly from these stations by electronic mail, internet and satellite. This increase in the number of stations and the more timely receipt of data has allowed us and other seismological centers to locate earthquakes more rapidly and to locate many small earthquakes which were undetected in earlier years. The NEIC now locates about 20,000 earthquakes each year or approximately 50 per day. Also, because of the improvements in communications and the increased interest in the environment and natural disasters, the public now learns about more earthquakes. \n\nAccording to long-term records (since about 1900), we expect about 17 major earthquakes (7.0 - 7.9) and one great earthquake (8.0 or above) in any given year.
