What is the world's only active volcano that erupts natrocarbonatite lava?
Ol Doinyo Lengai is an active volcano located in Tanzania. It uniquely produces natrocarbonatite lava. Due to this unusual composition, the lava is erupted at relatively low temperatures (approx. 500-600 °C). This temperature is so low that the molten lava appears black in sunlight, rather than having the red glow common to most lavas.
Why was the largest Hawaiian lake disappeared from the face of the earth?
was flooded with lava. Green Lake with a surface area of 0.8 hectares and a maximum depth of 6 metres, it was the largest natural freshwater lake in the Hawaiian Islands. On June 2, 2018, the lake was destroyed when lava flows from Kīlauea's lower Puna eruption boiled it away and completely filled the entire basin

Which country had its capital completely destroyed by volcano eruption?
Montserrat. On 18 July 1995, the previously dormant Soufrière Hills volcano, in the southern part of the island, became active. Eruptions destroyed Montserrat's Georgian era capital city of Plymouth. Between 1995 and 2000, two-thirds of the island's population was forced to flee, primarily to the United Kingdom, leaving fewer than 1,200 people on the island as of 1997 (rising to nearly 5,000 by 2016)
Which year is known as the Year Without a Summer?
1816. The year 1816 is known also the Poverty Year and Eighteen Hundred and Froze To Death because of severe climate abnormalities that caused average global temperatures to decrease by 0.4–0.7 °C (0.7–1.3 °F). This resulted in major food shortages across the Northern Hemisphere. Evidence suggests that the anomaly was predominantly a volcanic winter event caused by the massive 1815 eruption of Mount Tambora in the Dutch East Indies.
Nearest which capital is this volcano located?
Mexico. Popocatépetl is 70 km (43 mi) southeast of Mexico City, from where it can be seen regularly, depending on atmospheric conditions. Until recently, the volcano was one of three tall peaks in Mexico to contain glaciers. It is linked to the Iztaccihuatl volcano to the north by the high saddle known as the Paso de Cortés.
What is a lahar?
Ash mud flow. A lahar is a violent type of mudflow composed of a slurry of pyroclastic material, rocky debris and water. Lahars are extremely destructive: they can flow tens of metres per second, they have been known to be up to 140 metres deep, and large flows tend to destroy any structures in their path. They have even been known to decimate entire settlements.
