Earthquakes in Missouri
Earthquakes in Missouri
Most Missourians are familiar with the large 1811-1812 earthquakes that occurred in the New Madrid Seismic Zone (NMSZ) in southeast Missouri and it extends into a multi-state area. However, Missouri experiences small earthquakes nearly every day. These earthquakes typically are too small to be felt but are recorded on seismographs, devices that measure the earth’s movement. While these earthquakes are more frequent in the NMSZ in southeast Missouri, they also occur on other faults located in Missouri and surrounding states.
Water Resources
Water Resources
We depend on water for drinking, food production, recreation and healthy ecosystems. We swim, fish, play and celebrate in and around water. Water pollution can impact us all. Missouri is blessed with an abundance of water and it takes all of us to protect it. You can take simple steps to protect our state’s water resources while at home, traveling on roads and trails, and while enjoying our waterways.
