A NASA satellite image shows a volcano on Russia's Kamchatka Peninsula that has awoken after more than 400 years of slumber.
Krasheninnikova first began spilling lava and spitting up ash on the morning of August 3 2025, according to reports from the Kamchatkan Volcanic Eruption Response Team.
It has stayed active ever since, erupting ash, volcanic gases and lava.
The image by the instrument OLI-2 (Operational Land Imager-2) on the Landsat 9 Earth observation satellite captured this ongoing activity on November 14.
Landsat 8 was built, tested and launched by NASA, while the U.S. Geological Survey (USGS) operates it and manages the data collection.
"A volcanic plume billows from one of Krasheninnikova's craters and drifts to the northwest. This eruption has lofted plumes several kilometers above the crater rim, leading authorities to keep the aviation color code elevated to orange. A recent lava flow extends to the northeast, contrasting with the snowy slopes," said NASA in a statement.
Code orange typically means a volcano is exhibiting heightened unrest with increased likelihood of eruption or volcanic eruption is underway with no or minor ash emission.
The episode began five days after an earthquake shook the peninsula.
The epicenter of the earthquake, one of the strongest recorded by modern seismic instruments, according to the Earth Observatory, was about 240 kilometers (150 miles) south of the volcano.
The earthquake struck on July 29 2025, triggering Pacific-wide tsunami watches and warnings, according to the USGS.
"In keeping with a volcano that had not erupted or shown any signs of activity in about 400 years," said Paul Lundgren, a geophysicist at NASA's Jet Propulsion Laboratory, which used a remote sensing technique to measure how much ground in southern Kamchatka shifted after the earthquake, in a statement.
He added: "I would consider this eruption as triggered by the magnitude 8.8 earthquake."
Krasheninnikova has two overlapping stratovolcanoes -- cone-shaped bodies with steep sides, formed by viscous, explosive magma -- within a caldera.
The eruption that formed this cauldron-like hollow appears to date back around 30,000 years, while the volcano's previous eruption occurred around 1550 and produced lava flows from both summit cones, Earth Observatory reported.
While Krasheninnikova may have been triggered by the recent earthquake, NASA noted that it is common for multiple Kamchatka volcanoes to erupt at the same time.
