High-level eruption at Manam volcano, P.N.G.

Manam volcano eruption at 17:50 UTC on April 17, 2022

A high-level eruption started at Manam volcano, Papua New Guinea at 16:20 UTC on April 17, 2022.

According to the Darwin VAAC, volcanic ash was observed on RGB and Visible satellite imagery moving N and NW.

IR temperature of approximately -71 °C (95.8 °F) resulted in a height estimate of 13.7 km (45 000 feet).

The Aviation Color Code was raised to Red.1

Satellite imagery acquired at 05:40 UTC on April 18 indicated that ash from the volcano has dissipated.

There are no further reports of new or ongoing eruption, but the Aviation Color Code remains at Red, as of 06:30 UTC on April 18.

Several eruptions took place at Manam volcano, Papua New Guinea on March 8 and 9, 2022. The largest sent volcanic ash up to 15.2 km (50 000 feet) above sea level, drifting W and toward the main island.

A series of high-level eruption were reported at the volcano beginning on December 8, 2018, and lasting through January 24, 2019:

Geological summary

The 10 km (6.2 miles) wide island of Manam, lying 13 km (8 miles) off the northern coast of mainland Papua New Guinea, is one of the country’s most active volcanoes. Four large radial valleys extend from the unvegetated summit of the conical 1 807 m (5 928 feet) high basaltic-andesitic stratovolcano to its lower flanks.

These “avalanche valleys” channel lava flows and pyroclastic avalanches that have sometimes reached the coast. Five small satellitic centers are located near the island’s shoreline on the northern, southern, and western sides.

Two summit craters are present; both are active, although most historical eruptions have originated from the southern crater, concentrating eruptive products during much of the past century into the SE valley.

Frequent historical eruptions, typically of mild-to-moderate scale, have been recorded since 1616. Occasional larger eruptions have produced pyroclastic flows and lava flows that reached flat-lying coastal areas and entered the sea, sometimes impacting populated areas.2
