Quake activity perks up again at Hawaii’s Kilauea volcano

HILO, Hawaii — Seismic activity is increasing again along parts of Hawaii’s Kilauea volcano, though scientists maintain there is no imminent threat of eruption.About 36 minor and shallow earthquakes were detected in 24 hours along the volcano’s summit caldera, with 87 total quakes beneath the Upper East Rift Zone area, the USGS said Friday.  Most of the quakes had a magnitude of less than 2.0.That part of the volcano has been experiencing periods of increased seismic activity through the summer. Quakes perked up in late July, creating cracks on the Chain of Craters Road. A month later, the road was closed for a week after cracks suddenly grew in size and depth amid more quake activity.The road has since reopened as conditions stabilized.HAWAII NATIONAL PARK GIVES OK TO DRIVE ON CRACKED ROADS AFTER SEISMIC ACTIVITY WANESOther parts of the volcano have maintained low activity levels, the USGS said, and the volcano remains under a Yellow/Advisory level which is the second rung on the USGS’s four-level volcano alert scale. But the agency warns conditions can change quickly on the world’s most active volcano.
