14. Local Events Possibly Affecting Computed Position
14.01 Date : a few months after the end of June 2000
Event : a dike intrusion and co-seismic offsets between the Izu islands
Additional Information : The baseline length between Kashima
and Miura was shortened by about
3 cm. The crustal deformation at
Miura, located about100 km NNE
of the Izu islands, is caused
by a dike intrusion at about 3 km
depth and co-seismic offsets between
the islands. As of mid-September
2000, the crustal deformation around
Izu islands and the baseline
shortening had almost decayed.
