Please answer the following question: Information: - The Volcanic Explosivity Index (VEI) is a relative measure of the explosiveness of volcanic eruptions. It was devised by Chris Newhall of the United States Geological Survey and Stephen Self at the University of Hawaii in 1982. - Mount Tambora is an active stratovolcano which is a peninsula of and the highest peak on the island of Sumbawa in Indonesia. Sumbawa is flanked both to the north and south by oceanic crust, and Tambora was formed by the active subduction zone beneath it. This raised Mount Tambora as high as , making it one of the tallest peaks in the Indonesian archipelago in the 18th century. After a large magma chamber inside the mountain filled over the course of several decades, volcanic activity reached a historic climax in the eruption of 10 April 1815. This eruption had a volcanic explosivity index (VEI) of 7, the only unambiguously confirmed VEI-7 eruption since the Lake Taupo eruption in about AD 180. (The 946 eruption of Paektu Mountain might also have been VEI-7.) Tambora's last eruption was in 1967. It was rated VEI-0. - A chemical element or element is a species of atoms having the same number of protons in their atomic nuclei (i.e. the same atomic number, "Z"). There are 118 elements that have been identified, of which the first 94 occur naturally on Earth with the remaining 24 being synthetic elements. There are 80 elements that have at least one stable isotope and 38 that have exclusively radioactive isotopes, which decay over time into other elements. Iron is the most abundant element (by mass) making up Earth, while oxygen is the most common element in the Earth's crust. - Indonesia (or ; Indonesian: ), officially the Republic of Indonesia, is a unitary sovereign state and transcontinental country located mainly in Southeast Asia with some territories in Oceania. Situated between the Indian and Pacific oceans, it is the world's largest island country, with more than seventeen thousand islands. At , Indonesia is the world's 14th-largest country in terms of land area and world's 7th-largest country in terms of combined sea and land area. It has an estimated population of over 260 million people and is the world's fourth most populous country, the most populous Austronesian nation, as well as the most populous Muslim-majority country. The world's most populous island of Java contains more than half of the country's population. - A metal (from Greek "metallon", "mine, quarry, metal") is a material (an element, compound, or alloy) that is typically hard, opaque, shiny, and has good electrical and thermal conductivity. Metals are generally malleable that is, they can be hammered or pressed permanently out of shape without breaking or cracking as well as fusible (able to be fused or melted) and ductile (able to be drawn out into a thin wire). About 91 of the 118 elements in the periodic table are metals, the others are nonmetals or metalloids. Some elements appear in both metallic and non-metallic forms. - The Northern Hemisphere is the half of Earth that is north of the equator. For other planets in the Solar System, north is defined as being in the same celestial hemisphere relative to the invariable plane of the solar system as Earth's North pole. Due to the Earth's axial tilt, winter in the Northern Hemisphere lasts from the December solstice (typically December21 UTC) to the March Equinox (typically March20 UTC), while summer lasts from the June solstice (typically June21 UTC) through to the September equinox (typically September23 UTC). The dates vary each year due to the difference between the calendar year and the astronomical year. - Sulfur or sulphur (see spelling and etymology) is a chemical element with symbolS and atomic number16. It is abundant, multivalent, and nonmetalic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with chemical formula S. Elemental sulfur is a bright yellow crystalline solid at room temperature. Chemically, sulfur reacts with all elements except for gold, platinum, iridium, tellurium, and the noble gases. - This year was known as the ' Year Without a Summer ' because of low temperatures in the Northern Hemisphere , the result of the Mount Tambora volcanic eruption in Indonesia in 1815 . The sulfur from this eruption reflected the sun 's rays and caused global cooling . - A magma chamber is a large underground pool of liquid rock found beneath the surface of the Earth. The molten rock in such a chamber is under great pressure, and given enough time, that pressure can gradually fracture the rock around it creating outlets for the magma. If it finds a way to the surface, then the result will be a volcanic eruption; consequently many volcanoes are situated over magma chambers. Magma chambers are hard to detect, and most of the known ones are therefore close to the surface of the Earth, commonly between 1km and 10km under the surface. In geological terms, this is extremely close to the surface, although in human terms, it is considerably deep underground. - Sumbawa is an Indonesian island, in the middle of the Lesser Sunda Islands chain, with Lombok to the west, Flores to the east, and Sumba further to the southeast. It is part of the province of West Nusa Tenggara, but there are presently steps being taken by the Indonesian government to turn the island into a separate province. Traditionally the island is known as the source of sappanwood used to make red dye, as well as honey and sandalwood. Its savanna-like climate and vast grassland is used to breed horses and cattle and to hunt deer. Sumbawa has an area (including minor offshore islands) of (three times the size of Lombok) with a current population (January 2014) of around 1.39 million. It marks the boundary between the islands to the west, which were influenced by religion and culture spreading from India, and the region to the east that was less influenced. In particular this applies to both Hinduism and Islam. - The year 1816 is known as the Year Without a Summer (also the Poverty Year, the Summer that Never Was, Year There Was No Summer, and Eighteen Hundred and Froze to Death) because of severe climate abnormalities that caused average global temperatures to decrease by 0.40.7C (0.71.3F). This resulted in major food shortages across the Northern Hemisphere. What is the relationship between '1816' and '1816'?
