Russia's Volcanic Activity

 According to source Russia contains 117 Holocene Volcanoes. "Holocene" refers to the current geological time period, spanning from 11700 years ago to now. Of the volcanoes in Russia, 61 are currently considered active source. Something interesting is that this source states that there are 77 volcanoes currently in Russia, conflicting with the 117 from the previous source. Making the assumption that both sources are credible (the first being a .edu and the second being a .info, which I think is credible) there could be a good reason for the difference in data. Volcano.si.edu lists each volcano individually, and the reason they list more could be because of the inclusion of volcanoes thousands of years ago which worlddata.info may not count (for example, the Bolshoi-Kekuknaysky volcano last erupted in 5310 BCE), and also the fact that volcano.si.edu also counts all volcanoes on shared boundaries, which might be excluded from the other website's count.

In the Kamchatka Peninsula, as a part of the ring of fire contains 29 active volcanoes source. This source lists an even bigger number of volcanoes in the Kamchatka Peninsula (130), which is likely due to including most volcanoes in every epoch, not just the Holocene epoch. According to the same source, the Kuril-Kamchatka island arc contains "nearly 10% of the world's active vKutkholcanoes." I am assuming the word "vKutkholcanoes" is an attempt at spelling volcano. A map of the volcanoes in the Kuril-Kamchatka arc can be seen below.

    Very interesting!-what type of mitigation measures you'd suggest for this hazard?

Russia Summary + Disasters:

Image
Russia is the largest country (in terms of land mass) spanning around 17 million square kilometers. Currently, Russia consists of 8 federal districts, and (based on a 2022 estimate) has a population of around 147 million people. There is currently an international conflict between Russia and Ukraine, which began in 2014 after Russia annexed Crimea. The serious nature of this war shouldn't be understated, and it should be noted that the government of Russia is largely to blame for this terrible tragedy. Tens of thousands of people have lost their lives in the war, and even though I am writing about Russia, this doesn't mean I support Russia in any way.  Natural Hazards are any disturbance not directly caused by human influence (happens naturally) which have the potential to endanger people or things owned by people. A Natural Disaster is a Natural Hazard which caused one of these four things: Ten or more people died because of the disaster, One hundred or more people were effect

Heat Waves in Russia

Image
 Two notable heat waves which have occurred recently in Russia include a heat wave in 2010, and a heat wave in 2020. According to metoffice.gov.uk (siting the The World Meteorological Organisation) a heatwave is "a period of more than 5 consecutive days where the daily maximum temperature exceeds the average maximum temperature by 5°C or more." According to metoffice.gov.uk , the Russian heatwave in 2010 occured due to a "Blocking High" which seems to be a concentrated point of high pressure. Primarily because of this tragic event, Moscow reported over 14000 deaths in July 2010. From around January 2020 to June 2020, Siberian regions experienced an extreme heat wave likely due to climate change.   This image (taken from worldweatherattribution.org ) Shows the difference between the average temperatures during the heatwave and the average temperatures from 1981 - 2010 during the same months. worldweatherattribution.org states that "The results showed with hi
