The GeoNet volcano observatory reported that 84 quakes have been registered of which two have been located with magnitude more than M 3. Earthquakes in the area occur at shallow levels of about 15 km and the recent events don't differ as were detected in the range of 3 to 16 km depth.
Locations of quakes were distributed mostly in a NE-SW pattern along the east shore and in the center of the lake, but also around the Wairakei geothermal system, which may suggest that a fault zone has been activated in this area.
Earthquake swarms are common in the Taupō Volcanic Zone (TVZ), and several are recorded each year. Larger ones have lasted weeks-to-months and can include many hundreds of earthquakes.
