WATERLOO (KWWL) -- Since experts began taking seismic records in Iowa, 13 earthquakes have hit within the state.

The most recent was in 2004 in Fremont County.  The second most recent earthquake happened in 1948 in Oxford.  Click here for a map and the complete list from the Iowa Geological Survey.

Geologists say the most severe earthquake to ever impact Iowa was the New Madrid earthquake in 1812.  It was centered in southeast Missouri and actually made the Mississippi River flow backwards for a time.

The estimated total number of people killed in earthquakes in 2009 was 1,783.  1,117 of those died after a 7.5 magnitude quake in Indonesia.  An 8.1 magnitude quake in Samoa killed 192 people.

The 2009 estimated total was significantly lower than the 2008 total.  An estimated 88,000 people died in earthquakes in 2008.  A large amount of those deaths occurred after the 7.9 magnitude earthquake in Sichuan, China.
