In New Zealand, the supervolcano known as Lake Taupo to the south of the city of Taupo just had its alert level raised for the first time on record. This change was made in response to a series of several hundred earthquakes and volcanic uplift which has been detected in the eastern section of the lake, meaning that magma and hydrothermal fluids are on the move. Although these swarms are not as energetic as previous episodes of unrest, they are related to the movement of magma at depth. This video will discuss the implications of this earthquake swarm, and how common periods of seismic unrest are at this supervolcano.
