1. A method performed by a first node for managing a movement of a radio antenna, the first node operating in a wireless communications network, the method comprising:
determining whether the movement of the radio antenna due to a velocity of a wind or a seismic activity is above a threshold over a time period,
wherein the radio antenna is connected to a second node operating in the wireless communications network,
wherein the movement is with respect to at least one wireless device operating in the wireless communications network,
wherein the determining is based on an analysis of one or more properties of radio transmissions to or from the radio antenna over the time period, and
wherein the analysis is based on:
obtained measurements of at least a phase of the radio transmissions over the time period;
a division of the obtained measurements in subsets of periods of time comprised in the time period;
a Fourier transform over each of the subsets of periods of time; and
wherein the determining is further based on a set of Doppler spectrum values obtained from the Fourier transform over each of the subsets of periods of time; and
initiating the providing of a message to one of: the second node and a third node operating in the wireless communications network, wherein the initiation of the providing of the message is based on a result of the determination.
