Results from the December 1998 deformation survey about Taupo Volcanic Centre are now to hand. These surveys are conducted three monthly. The results from the December 1998 survey show generally insignificant changes since the September survey.
Two long-term trends have been apparent in the Taupo deformation data:
The subsidence along the northern shores, represented by data from Kinloch, has been observed since the early 1980’s, while the uplift about the lake centre has been observed since mid-1995. The latest results show the subsidence across the northern shores is continuing to slow, while no further uplift has occurred at Horomatangi Reef.
In the September to December 1998 period three earthquakes were reported as felt in the Taupo area. This level of earthquake activity is considered normal for the Taupo area.
The Volcanic Alert Level for Taupo volcano remains at Level 0.
