bradyseism การใช้

• The area is well known for its bradyseism.
• More recently, between 1968 and 1972, the Campi Flegrei area suffered an episode of positive bradyseism and rose by 1.7 metres.
• After the Irpinia earthquake in 1980 and the bradyseism of 1982, however, many displaced people sought shelter in Licola and its tourist industry went into a period of decline.
• These occur up to 7 metres up the columns, showing how bradyseism in the area lowered the land to at least this depth under the sea and subsequently raised it again.
• In the same area, the submerged town of Puteoli ( Pozzuoli, close to Naples ) contains the " portus Julius " created by Marcus Vipsanius Agrippa in 37 BC, later sunk due to bradyseism.
• The structure's magma chamber remains active as there apparently are solfataras, hot springs, gas emissions and frequent episodes of large-scale up-and downlift ground deformation ( Bradyseism ) do occur.
• This puzzling feature was the subject of debate in early geology, and eventually led to the identification of bradyseism in the area, showing that the Earth's crust could be subject to gradual movement without destructive earthquakes.
• It has been established that in Roman times, on the coastal stretch, now known as San Marco, east of the promontory, and to the right of the Testene, a seaside town called " Ercula " developed and flourished between the 1st century BCE, and the 5th century CE . Meanwhile, the harbour of neighbouring Poseidonia ( by then, renamed Paestum by the Romans ) became progressively silted up by the process of coastal bradyseism.
