In 1939, Ghana experienced its severest earthquake with a local magnitude of 6.5. It resulted in the death of 17 people and caused significant damage to property. Since then, there have been reported occurrences of earthquakes, though the region is generally considered a stable continental area with few active tectonic features. This seismic region is generally characterized by a major active fault line which stretches from the McCarthy Hill area in Accra westwards towards Kasoa-Nyanyanu in the Central Region and eastwards towards the Akwapim Ridge all the way to the Volta Region. The epicenter of the 22 June 1939 earthquake is located 25 km off the coast of Accra near Kasoa-Nyanyanu in the west. An earthquake occurrence and observation survey was conducted in March 2019, following three earthquakes recorded in March and December 2018 and March 2019 with local magnitude ranging from 3.0 to 4.8. The events were mostly felt by residents in the southern part of the country, who were consequently thrown into a state of panic. The main objective of the survey was to assess the perception, experiences, and adaptation strategies to seismic events of randomly sampled residents of the area. Questionnaires were administered during the survey in the Awutu Senya East and Weija-Gbawe Municipalities. It was found that though the majority of residents are aware that they live in an earthquake prone area, they have put little to no measures in place to mitigate the seismic risk.

加纳的地震风险：努力和挑战

1939年，加纳经历了6.5级的最大地震。这导致17人死亡，并对财产造成重大破坏。从那时起，据报道发生了地震，尽管该地区通常被认为是稳定的大陆区域，几乎没有活跃的构造特征。该地震区的主要特征是一条主要的活动断层线，该断层线从阿克拉的麦卡锡山地区向西延伸到中部地区的卡索阿-尼亚扬，然后向东延伸至阿克瓦匹姆岭，一直延伸至伏打地区。1939年6月22日地震的震中位于阿克拉（Accra）海岸25公里附近，靠近西部的Kasoa-Nyanyanu。2019年3月进行了地震发生和观察调查，在2018年3月，2018年12月和2019年3月记录了三场地震之后，当地震级范围为3.0至4.8。该事件主要是由该国南部的居民感到的，他们因此陷入了恐慌状态。这项调查的主要目的是评估对该地区随机抽样居民的地震事件的感知，经验和适应策略。在调查过程中，对东部Awutu Senya和Weija-Gbawe市政当局进行了问卷调查。人们发现，尽管大多数居民都知道他们生活在地震多发地区，但他们几乎没有采取任何措施来减轻地震危险。因此，他们陷入了恐慌状态。这项调查的主要目的是评估对该地区随机抽样居民的地震事件的感知，经验和适应策略。在调查过程中，对东部Awutu Senya和Weija-Gbawe市政当局进行了问卷调查。人们发现，尽管大多数居民都知道他们生活在地震多发地区，但他们几乎没有采取任何措施来减轻地震危险。因此，他们陷入了恐慌状态。这项调查的主要目的是评估对该地区随机抽样居民的地震事件的感知，经验和适应策略。在调查过程中，对东部Awutu Senya和Weija-Gbawe市政当局进行了问卷调查。人们发现，尽管大多数居民都知道他们生活在地震多发地区，但他们几乎没有采取任何措施来减轻地震危险。
