Hawaii is still on fire?
After Kilayue Volcano’s eruption for 4 destructive month (May 2018- Sept 2018), it seemed to finally calm down. Thought the lava kept destroying the adjacent land and producing toxic gases even after September, in 2019 the volcano seemed to cease its seismic activity.

Kīlauea Activity Summary: Kīlauea Volcano is not erupting. Monitoring data continue to show steady rates of seismicity and ground deformation, low rates of sulfur dioxide emission, and only minor geologic changes since the end of eruptive activity in September 2018. Water has begun pooling at the lowest elevations in summit crater. Currently there are two small puddles that began forming on July 25, 2019 and August 1, 2019. These puddles continue to slowly expand and deepen.
Mauna Loa Activity Summary: Mauna Loa Volcano is not erupting. Over the past week, rates of deformation and seismicity continue to remain slightly elevated.
Observations: During the past week, approximately 46 small-magnitude earthquakes (all less than M2.0) occurred beneath the summit and upper Southwest Rift Zone. Most of the earthquakes occurred at shallow depths of less than 5 km (~3 miles).
Global Positioning System (GPS) and Interferometric Synthetic Aperture Radar (InSAR) measurements show continued summit inflation, suggestive of recharge of the volcano's shallow magma storage system.
No significant changes in volcanic gas release at Sulphur Cone on the Southwest Rift Zone were measured. Fumarole temperatures at both Sulphur Cone and at the summit remain stable.
"We are uncertain how much longer the activity will continue," Stovall said. "We're seeing more of the same types of things we've seen for the past several weeks," such as lava oozing through residential neighborhoods into the ocean.
Another volcanologist, Tracy Gregg of the University at Buffalo, said, "There's no way to know how much longer the eruption will last."
At the Kilauea summit, the Halemaumau crater has doubled in size since May, the U.S. Geological Survey said.
