Magnetic Etna 2016 (EMFC_2016)

The data represent the total intensity (F) of the Earth's magnetic field (or geomagnetic field) acquired continuously by the stations of the Etna permanent network from XX to YY. All the stations are located along a South-North profile that crosses the summit area of ​​Etna and are equipped with Overhauser effect scalar magnetometers with a sensitivity of 0.01 nT. The network also includes a reference station located in Cesarò on the Nebrodi Mountains. The data are synchronized by a GPS and is acquired with a sampling rate of 5-10 seconds. Time series of geomagnetic data allow to observe and evaluate the anomalous variations of the magnetic field associated with the modifications of the stress field and of the thermodynamic state produced by magma rising in the more superficial layers of the volcano. The continuous data analysis therefore contributes to the evaluation of the spatio-temporal evolution of the dynamics in progress.

本数据集收录埃特纳永久台站网络于XX至YY时段连续采集的地球磁场（地磁场）总强度（F）观测数据。所有台站均沿穿越埃特纳火山主峰区的南北剖面布设，均配备灵敏度为0.01纳特（nT）的奥弗豪泽效应（Overhauser effect）标量磁力仪。该台站网络还包含一座位于内布罗迪山脉切萨罗（Cesarò）的参考台站。所有数据通过GPS实现同步，采样率为5至10秒。地磁数据时间序列可用于观测与评估与火山浅层岩浆上升引发的应力场及热力学状态变化相关的磁场异常变化。因此，对该连续观测数据开展分析，有助于评估当前火山动力学过程的时空演化特征。
