The New Zealand ski resort towns of Queenstown and Wanaka were shaken by a 6.0-magnitude earthquake Monday.

No injuries have yet been reported after the quake, which struck at 2:29 p.m. local time, with its epicenter 30 km northwest of the tourist town of Wanaka, in the South Island, and at a depth of 5 km.

The government's GeoNet earthquake monitoring agency rated the quake's intensity as severe.

A moderate aftershock of 3.5-magnitude struck in the same place just eight minutes later.

Radio New Zealand reported that no damage had yet been reported and that witnesses said the shaking lasted for more than 15 seconds.
