On this day in , Mount Tambora, seen here on April 10, ,by the Himawari-8 satellite produced the largest volcanic eruption ever recorded.
Mount Tambora, located on the island of Sumbawa in present-day Indonesia, is an active stratovolcano that was one of the tallest mountains in all of Indonesia before its eruption. After the event, its height decreased from 14, feet to just under 10, The explosion, which ejected a volume of approximately 31 cubic miles of ash, rated a Volcanic Explosivity Index or VEI of 7 out of a logarithmically-based scale of 10 due to its destructive effects , on a scale and severity not seen since the AD explosion of Lake Taupo in New Zealand.
Active fumaroles, or steam vents, still exist in the caldera. The image was taken by the Expedition 20 crew. The image in this article has been cropped and enhanced to improve contrast. Lens artifacts have been removed. The International Space Station Program supports the laboratory to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the Internet.
Caption by William L. Volcanic Hazard Maps The IAVCEI Commission on Volcanic Hazards and Risk has a Volcanic Hazard Maps database designed to serve as a resource for hazard mappers or other interested parties to explore how common issues in hazard map development have been addressed at different volcanoes, in different countries, for different hazards, and for different intended audiences.
In addition to the comprehensive, searchable Volcanic Hazard Maps Database, this website contains information about diversity of volcanic hazard maps, illustrated using examples from the database.
This site is for educational purposes related to volcanic hazard maps. Hazard maps found on this website should not be used for emergency purposes.
For the most recent, official hazard map for a particular volcano, please seek out the proper institutional authorities on the matter. For each MODIS image, the algorithm automatically scans each 1 km pixel within it to check for high-temperature hot-spots. When one is found the date, time, location, and intensity are recorded.
MODIS looks at every square km of the Earth every 48 hours, once during the day and once during the night, and the presence of two MODIS sensors in space allows at least four hot-spot observations every two days. Each day updated global maps are compiled to display the locations of all hot spots detected in the previous 24 hours.
There is a drop-down list with volcano names which allow users to 'zoom-in' and examine the distribution of hot-spots at a variety of spatial scales. Sentinel Hub is an engine for processing of petabytes of satellite data. It is opening the doors for machine learning and helping hundreds of application developers worldwide. It makes Sentinel, Landsat, and other Earth observation imagery easily accessible for browsing, visualization and analysis.
Users can customize a variety of filters and options in the left panel. Note that if there are no stations are known the map will default to show the entire world with a "No data matched request" error notice. Users can customize the data search based on station or network names, location, and time window. Requires Adobe Flash Player.
The Deep Earth Carbon Degassing DECADE initiative seeks to use new and established technologies to determine accurate global fluxes of volcanic CO 2 to the atmosphere, but installing CO 2 monitoring networks on 20 of the world's most actively degassing volcanoes. The group uses related laboratory-based studies direct gas sampling and analysis, melt inclusions to provide new data for direct degassing of deep earth carbon to the atmosphere.

In China and Tibet, unseasonably cold weather killed trees, rice, and even water buffalo. Floods ruined surviving crops. Failing crops and rising prices in and threatened American farmers. Odd as it may seem, the settling of the American heartland was apparently shaped by the eruption of a volcano 10, miles away.
Thousands left New England for what they hoped would be a more hospitable climate west of the Ohio River. Partly as a result of such migration, Indiana became a state in and Illinois in They cite historian L. Stillwell, who estimated that twice the usual number of people left Vermont in and —a loss of some 10, to 15, people, erasing seven years of growth in the Green Mountain State.
In Europe and Great Britain, far more than the usual amount of rain fell in the summer of It rained nonstop in Ireland for eight weeks. The potato crop failed. Famine ensued. The widespread failure of corn and wheat crops in Europe and Great Britain led to what historian John D.
Typhus broke out in Ireland late in , killing thousands, and over the next couple of years spread through the British Isles. Researchers today are careful not to blame every misery of those years on the Tambora eruption, because by a cooling trend was already under way. In Switzerland, the damp and dark year of stimulated Gothic imaginings that still entertain us.
