Supplemental Material: Magma recharging beneath the Weishan volcano of the intraplate Wudalianchi volcanic field, northeast China, implied from 3-D magnetotelluric imaging

Details on the 3-D magnetotelluric inversion, estimating melt fractions based on resistivity and velocity anomalies, earthquake activity, and the interpretation of low-resistivity anomalies by magmas and no apparent hydrothermal alterations for the Weishan volcano.
