Scientists are using satellites and helicopters to map lava flows from the Mauna Loa volcano, and say they're seeing the lava continue its slow progress across the Big Island.
The Mauna Loa on the island of Hawaii, which is the world's largest active volcano, has erupted for the first time in 38 years.

The Mauna Loa on the island of Hawaii, which is the world's largest active volcano, has erupted for the first time in 38 years.

Officials were initially concerned that lava flowing down the side of the volcano would head toward the South Kona district.
Scientists later assured the public that the eruption migrated to a rift zone on Mauna Loa's north-east flank and was not threatening any communities.

As the eruption reaches its second week, the lava flow marches slowly north toward the Daniel K. Inouye Highway, which remains open to traffic in both directions.

"There's no signs of the flow stopping at any immediate term because activity up at that event on the north-east drift zone continues steadily," US Geological Survey Geologist Mike Zoeller said.
"We still see high rates of lava fusion into the upper lava channels in that region."

In some places the lava has been advancing at about 20 meters per hour. In channels closer to the vent it advances at 8.2-11 metres per second.
Mauna Loa, rising 4,169 metres above sea level, is the much larger neighbour to Kilauea volcano, which erupted in a residential neighbourhood and destroyed 700 homes in 2018.
