NEW YORK (AP) — Another earthquake that shook the northern section of Japan rattled the stocks of insurance and reinsurance companies on Thursday.

The magnitude-7.4 aftershock knocked out power across a large portion of the area that was devastated by the March 11 earthquake and tsunami, which killed about 25,000 people, tore apart entire communities and triggered an ongoing crisis at a nuclear power plant.

A new tsunami warning was issued following the aftershock, but cancelled about 90 minutes later.
