While smaller US earthquakes made recent news, like the 6.5 magnitude shake in Northern California that was felt up into central Oregon, the 7.0 magnitude earthquake that struck near Port-au-Prince, Haiti yesterday, has brought earthquakes into the foreground of national news and media reports - and thus in the awareness of students.
According to reports, the quake in Haiti, an area where earthquakes are not common, was the strongest in 200 years. The world map of earthquakes in the last 7 days on the USGS site shows four earthquakes in the Haiti area, including a 5.3 magnitude shake this morning. While the extent of the damage has not yet been determined, the immediate and visible effects indicate that the quakes were devastating to the small Caribbean country.
The following Science Buddies Project Ideas can help students and classes talk about both the geology of earthquakes as well as civil engineering and the kinds of considerations that go into designing stronger and more earthquake-resistant structures.
