This folder contains a dataset of 53 MT stations, collected nearby Mt. Paektu volcano during 2016-2023. 44 sites are densely located nearby the volcano, the remaining 9 sites, are located from the volcano to Samjiyon, and Mt. south Potae (for whole inversion), DPRK of Korea (see paper for details). The minimum and maximum distances between neighboring sites are 83 m and 5230 m, respectively. MT data are acquired using a 5-channel receiver, three magnetic induction sensors, and two electrical dipoles with Pb-PbCl2 electrodes, manufactured in Kim Chaek University of Technology (KUT). Data acquisition at each site was performed for 2 days on average, and are remotely referenced with a distant site with other similar instruments (Pyongwon observatory, 39°18′23″N, 125°35′35″E), which is located about 360 km south-west away from the volcano summit. All data at field sites and remote site were sampled at three sampling frequencies 2400 Hz, 240 Hz, and 15 Hz.

The acquisition co-ordinate system was with "X" aligned northward, and "Y" aligned along eastward. The EDI (Electrical Data Interchange: “The Society of Exploration Geophysicists, MT / EMAP Data Interchange Standard”) data are in that coordinate system. The station coordinates are given in the header of each file.
