Strong wave destroys turtle eggs following massive earthquake near El Salvador

Last update: August 30, 2012 at 9:28 pm by By

Earthquake overview : A massive earthquake barely felt in El Salvador generated a tsunami with waves up to 3 meter. The waves washed away nearly 45000 eggs of a very vulnerable turtle species.

El Salvador-only earthquake list

A strange set of earthquake data occurred following the El Salvador earthquake a few days ago with various agencies giving very different magnitudes for the event.

A tsunami alert was also triggered and then was cancelled.

We have brief reports that have encircled the globe that the following damage occurred due to 3 strong waves after the earthquake:

- A Zoological foundation has said that 3 waves up to 3m high (not 8m as stated in some reports) washed onshore and destroyed around 45000 just hatched turtle eggs. This is around 6% of the total endangered eggs saved in the last 1.5 years. These were all of the Ridley turtle variety which is very much endangered. It also destroyed the hatcheries for turtle protection.

- The tsunami waves washed up on about 150 people collecting the eggs to protect them in special pens

- The waves injured 6 of the people who were all saved.

- No other reports of damage or a felt tsunami have been made. The earthquake was barely felt in El Salvador.

- Over 200 aftershocks have since been registered.
