Location of the earthquakes and other earthquakes that have occurred in South Sudan.

Earthquake I focus on occurred on May 20 1990--> there was an overall chain of earthquakes around this time. The first being on May 19th and the last being May 25th in the year 1990

Magnitude: 7.2

Depth: 14.9 km

Occured along divergent plate boundaries

Example of the type of boundary this earthquake was based on and the affects of this plate movement.

Recorded magnitude and epicenter from a seismograph in Oak Ridge Massachusetts.

Took 28 seconds for the P waves to arrive, 49 seconds for the s waves to arrive. Epicenter 160 km from the capital, Juba.

Aftermath: there was no loss of lives or destruction--> based on where there epicenters was allowed for there to not be any serous damage to populated areas where lives could have been loss and buildings could have been destroyed, its epicenter was in a rural part of South Sudan.

Other earthquakes: The chain of earthquakes that mine falls into had some damage but no lives loss. For the amount of earthquakes that occurred and the magnitudes they were at they all had a good epicenter which helped to contribute to minimal damage and loss.

Overall: No economic loss for my general May 20th earthquake nor any loss of lives in any of the earthquakes. Some money was needed to rebuild small things in a few other earthquakes that occurred in the chains of earthquakes within that week.
