Kamchatka is home to 29 active volcanoes, part of a vast belt of Earth known as the “Ring of Fire” which circles the Pacific Ocean and is prone to eruptions and frequent earthquakes. Most of the peninsula’s volcanoes are surrounded by sparsely populated forest and tundra, so pose little...
The Ring of Fire is a Pacific region home to over 450 volcanoes, including three of the world’s four most active volcanoes – Mount St. Helens in the USA, Mount Fuji in Japan and Mount Pinatubo in the Philippines. It is also sometimes called the circum-Pacific belt. Around 90% of ...
Acid rain occursdue to the presence of certain pollutants in the atmosphere. Acid rain can be caused due to combustion of fossil fuels or erupting volcanoes, or rotting vegetation which releases sulfur dioxide and nitrogen oxide into the atmosphere. ...
2020, fire within the 30 km diameter Exclusion Zone around the Chernobyl reactor site that had a catastrophic meltdown in 1986. The 13 spectral bands from S-2 data were processed by ESA to show the smoke plumes and the bright active fire areas along the front edges of the burned area....
aNOAA scientists use current meters attached with turbidity sensors to gather data near underwater volcanoes and other highly active geological sites. Also, satellite imagery is used to observe turbidity by measuring the amount of light that is reflected by a section of water. 用浑浊传感器附有的...
The basin is surrounded by the stratovolcanoes Iztaccíhuatl and Popocatépletl (active) toward the west and Malinche toward the east. These stratovolcanoes have different elevations (5230, 5426 and 4461 m above sea level, respectively), and they are covered by recurrent snowfields during several...
A network of alien civilization heat islands may be resolved on the planetary surface and distinguished from environmental heat sources (e.g., volcanoes) through differential infrared measurements, e.g., at 5μm and 10μm. However, this observation would require an immense collecting area of ...
The presence of subaquatic volcanoes in the polar regions, resulting from tectonic activity, gives rise to hydrothermal regions within the polar ocean submergence zones. In these regions, seawater temperatures frequently reach up to 400 °C [42,120,121,122,123]. Therefore, the criteria for the ...

A close-up of a large clast from the recent lava fountaining at the summit of Kilauea, deposited on Crater Rim Drive within the closed area of Hawai'i Volcanoes National Park. The lava was very gas rich so this clast was very light, akin to the density of a kitchen sponge. USGS photo...
