The 1983 Liège earthquake occured on 8 november at 01:49 Central European Time, with the epicenter near Remicourt, in Liège province, Belgium. This earthquake's body wave magnitude measured 4.7 and had a depth of around 14km.[1] A Modified Mercalli Intensity of VIII (severe) was observed.[6]The event was followed by more than 10 aftershocks.[5] 2 people died, 30 were injured and over 16000 buildings were damaged.[6][4]The damage cost has been estaminated between 42 million and 75 million Euros.[2][3] It was the biggest earthquake since the 1938 Zulzeke earthquake in the history of Belgium.
Geological setting
The Liège province is situated on the southeastern corner of the Brabant Parautochthon and northeastern side of the Ardenne Allochthon, which are being seperared by the Midi-Eifelian Fault, a segment from the Variscan front thrust. The fault dates back to the Variscan orogeny, a late Paleozoic geologic mountain-building event.[7]
Earthquake
The earthquake which struck on the 8th of november in Remicourt, a munacipality northwest of Liège, was the biggest since the 1983 Zulzeke earthquake in Belgium. It was felt in Belgium, The Netherlands, Germany and Luxembourg. A maximum intensity of VIII (severe) has been observed.[6]More than 10 aftershocks have been registered, the biggest being a ML 3.4.[5] This disaster occured on the Midi-Eifellian fault, with a right latteral strike-slip fault mechanism at a depth of 14km.[1]The peak ground acceleration of the epicentral area was between 0.13-0.20 g.[4]
Impact
The total damage cost ranged from €42 million to €75 million .[2][3]Two individuals lost their lives, one of them due to a heart attack, along with 30 reported injuries.[6]The number of damaged buildings exceeded 16 000. The most common damaged structures were chimneys, roofs and walls.[4]Over 700 families were relocted.[7]
Response
A few weeks after the earthquake, the Belgian Government decided to reimburse part of the repair costs and invited the owners from the most affected localities to report the damage on their properties.[4]
