The U.S. Geological Survey Hawaiian Volcano Observatory says cracks continue to open and widen in Leilani Estates.

HVO released several images taken Thursday morning as geologists surveyed the area. Significant changes were observed during the past 24 hours.

An overflight at around 7 a.m. revealed significant cracking, like massive tears, along Pohoiki Road, many of which are “steaming,” or what scientists refer to as volcanic gas emissions.

Cracks on Nohea Street have expanded significantly, creating vertical gaps in the asphalt.

HVO says these cracks are caused by the underlying intrusion of magma into the lower East Rift Zone.
