Almost 98% of earthquakes occur at the boundary of a tectonic plates when they slide against one another. despite this, indiana still has seismic zones that experience increased seismic activity. this is particularly heavy in the wabash valley fault zone in the southwest corner of the state. how do you explain how seismic activity is felt in this area?

Answer

Seismic activities in this area are small and they are never even felt.

Explanation

Along the Indiana and Illinois border runs the Wabash valley seismic zone, which according to the United States Geological Services (USGS) data, lesser earthquake events happen relatively frequently along the line. Although Indiana is located near two powerful fault lines, it hasn’t produced life threatening earthquakes.

An earthquake occurs when there is a Shake or a fault in the earth. Therefore, this makes the tectonic plates to move slowly and but they are stuck at the edges because of friction. When resistance exceeds stress, then it causes the earthquake. It then releases energy that travels to the earth through the crust and making it shake as we feel it.  

California experiences different types of plates; the principal boundary between the plates the fault from San Andrea is that is about 650 miles long towards the depths with other smaller defects at San Jacinto.

a mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. this uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.a geomagnetic reversal is a change in a planet's magnetic field such that the positions of magnetic north and magnetic south are interchanged.
