Two moderate earthquakes, one of which registered as a magnitude 5 temblor, rattled the island of Hawaii on Friday morning and could be related to recent geologic activity at Mauna Loa in Hawai'i Volcanoes National Park, the U.S. Geological Survey reported.

Nāhuku lava tube in Hawaiʻi Volcanoes National Park is closed until further notice while geologists study its stability in the wake of movement of a large rock slab in the tube.

National parks across the country continue to lag behind a court-ordered schedule to complete air-tour management plans and are failing to conduct environmentally required studies as they develop those plans, according to Public Employees for Environmental Responsibility.

The monthslong eruption of Kīlauea volcano at Hawai'i Volcanoes National Park back in 2018 did a great deal of damage to the park and its infrastructure, including impacts to the Jaggar Museum and nearby buildings on the brim of the volcano that left them unusable. Now the National Park Service and U.S. Geological Survey are ready to move forward with a disaster recovery plan that is open for public comment.
