Hawaii: Mauna Loa of Hawaii, one of the world's largest volcano, has started erupting after a gap of nearly 40 years.

The US Geological Service (USGS) said on its website: "The eruption of Mauna Loa continues on the Northeast Rift Zone. Three fissures erupted and as of 1:30 PM, only the lowest of the three fissures was active. Estimates of the tallest fountain heights are between 100–200 ft (30 – 60 m), but most are a few yards (meters) tall."

"The fissures sent lava flows to the northeast and parallel to the rift zone. Lava flows from the two higher fissures moved downslope but stalled about 11 miles (18 km) from Saddle Road. Fissure 3 is currently feeding lava flows moving east parallel to the Northeast Rift Zone. These remain at above 10,000 feet elevation and over 10 miles (16 km) away from Saddle Road. We do not expect upper fissures to reactivate. However, additional fissures could open along the Northeast Rift Zone below the current location, and lava flows can continue to travel downslope," read the website.

"There is no active lava within Moku'āweoweo caldera, and there is no lava erupting from the Southwest Rift Zone," read the website.

The USGS said  any eruptive activity outside the Northeast Rift Zone is not expected.

"No property is at risk currently. There is a visible gas plume from the erupting fissure fountains and lava flows, with the plume primarily being blown to the Northwest," read the USGS website.
