In 1960 there was an extremely large earthquake in Chili. It actually happens to be the largest recorded earthquake in history. It was recorded at a 9.5. Normally during an earthquake the S waves come right after the P waves, but during this earthquake it was a little bit different, but that actually turned out to be lucky. The S waves did not come until 30 minutes after the P waves did and this was very lucky because most people had evacuated buildings after the first shock so they were safe when the second, bigger shock actually occured. Although, for the most part, there were no people in the buildings during the second and biggest shock, there still was a lot of damage caused to the buildings. Almost half a billion dollars in damage actually. Also, because of this earthquake, there were many tsunamis that were caused. This was definitely a terrible earthquake!
