2017 Chiapas earthquake

The 2017 Chiapas earthquake struck in the Gulf of Tehuantepec off the southern coast of Mexico near the state of Chiapas, approximately 87 kilometres (54 mi) southwest of Pijijiapan (alternately, 101 kilometres (63 mi) south-southwest of Tres Picos), with a Mercalli intensity of IX (Violent). The moment magnitude was estimated to be Mw8.2. The earthquake caused all of Mexico City to tremble, prompting people to evacuate after the early warning system was triggered. It also generated a tsunami with waves 1.75 metres (5 ft 9 in) above tide level; and tsunami alerts were issued for surrounding areas. Mexico's president called it the strongest earthquake recorded in the country in a century. It was also the second strongest recorded in the country's history, behind the magnitude 8.6 earthquake in 1787.

Hurricane Ivan hits Grenada

Hurricane Ivan was a large, long-lived, Cape Verde hurricane that caused widespread damage in the Caribbean and United States. The cyclone was the ninth named storm, the sixth hurricane and the fourth major hurricane of the active 2004 Atlantic hurricane season. The storm passed over Grenada on September 7, battering several of the Windward Islands. As it entered the Caribbean Sea, Ivan reintensified rapidly and became a Category 5 hurricane.

1999
1999 Athens earthquake

The 1999 Athens earthquake occurred on September 7 at 14:56:51 local time near Mount Parnitha in Greece with a moment magnitude of 6.0 and a maximum Mercalli intensity of IX (Violent). The proximity to the Athens metropolitan area resulted in widespread structural damage, mainly to the nearby suburban towns of Ano Liosia, Acharnes, Fyli, Thrakomakedones, Kifissia, Metamorfosi, Kamatero and Nea Filadelfeia. More than 100 buildings (including three major factories) across those areas collapsed trapping scores of victims under their rubble while dozens more were severely damaged. With damage estimated at $3-4.2 billion, 143 people were killed, and up to 1,600 were treated for injuries in Greece's deadliest natural disaster in almost half a century.

1950
John Friedrich was born

Johann Friedrich Hohenberger, also known as John Friedrich, was executive director of the National Safety Council of Australia (Victorian Division) during the 1980s. He was the subject of Victoria's biggest fraud case and known as "Australia's greatest conman". Hohenberger was a West German national. In August 1972, he began working as an independent contractor with the German road construction company Strassen und Teerbau. Around July 1974, he forged road building orders from distant mountain towns and used them to order Strassen und Teerbau to build roads. No roads were ever built, and no earthworks or materials were ever bought. Hohenberger embezzled 200,000 DM from the company.
