1656–1715 Maunder Minimum low sunspot activity; 1790–1830 Dalton Minimum low sunspot activity, cold; 1816 Year Without a Summer, caused by volcanic dust of Mount Tambora eruption; 1850–present Retreat of glaciers since 1850, instrumental temperature record; Present and recent past global warming, perhaps to be named the Anthropocene period
S P Crater is a cinder cone volcano 25 miles (40 km) north of Flagstaff, Arizona. [4] Saddle Crater; South Sheba Crater; Stewart Crater; Strawberry Crater; Sunset Crater is a cinder cone volcano in the San Francisco volcanic field, and a part of the Sunset Crater National Monument. [5] The Sproul
The Uinkaret volcanic field is an area of monogenetic volcanoes in northwestern Arizona, United States, located on the north rim of the Grand Canyon. [ 2 ] Lava flows from the Uinkaret volcanic field that have cascaded down into the Grand Canyon, damming the Colorado River , have been used to date the canyon's carving. [ 3 ]
The eruption poured over 17 million tons of the gas into the atmosphere and led to a global temperature decrease of around 0.5 degrees Celsius (0.9 degrees Fahrenheit) that lasted about a year ...
Those eruptions sent ash and volcanic debris into the air and across the landscape, with millions of miles of lava erupting over what was believed to be more than 600,000 years. ... was due to the ...
The San Francisco volcanic field is an area of volcanoes in northern Arizona, north of Flagstaff, US. The field covers 1,800 square miles (4,700 km 2 ) of the southern boundary of the Colorado Plateau .
The conversion of sulfur dioxide to sulfuric acid, which condenses rapidly in the stratosphere to form fine sulfate aerosols. A volcanic winter is a reduction in global temperatures caused by droplets of sulfuric acid obscuring the Sun and raising Earth's albedo (increasing the reflection of solar radiation) after a large, sulfur-rich, particularly explosive volcanic eruption.
Three large cooling periods caused by volcanic eruptions in 1641–1642, 1667–1694 and 1809–1831 respectively. [2] Also, some major volcanic eruptions caused the fall of the temperature. During the Little Ice Age, all major volcanic eruptions were stratovolcano, also known as composite volcanos. They were built by the escape of magma ...
