From the sinking of which ship, the tradition of "Women and children first" was born?
MV Wilhelm Gustloff
"Women and children first" is a code of conduct dating from 1852, whereby the lives of women and children were to be saved first in a life-threatening situation. HMS Birkenhead was wrecked on 26 February 1852, while transporting troops to Algoa Bay at Danger Point. There were not enough serviceable lifeboats for all the passengers, and the soldiers famously stood firm on board, thereby allowing the women and children to board the boats safely and escape the sinking.Only 193 of the estimated 643 people on board survived; including all women and children

What is the most explosive type of volcanic eruptions?
According to the Volcanic Explosivity Index, the strongest types of volcanic eruptions are Plinian/Ultra-Plinian. Some of the notable examples in that category include Lake Toba, Tambora and Krakatoa.
What is the typical source of pressure buildup inside a volcano?
centrifugal force of Earth rotation
boiling of rainwater
degassing of magma
The whole process begins when hot magma is lifted by convection to the magma chamber. As the pressure in the chamber is lower than deep in Earth's crust, the gas starts to release. Since degassed magma has lower density, it may then sink and be replaced with new one. This process may build up huge pressure of gases, eventually causing explosion.
Which country had its capital completely destroyed by volcano eruption?
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)
How fast do tsunami waves travel across the open ocean?
about 20 km/h
about 100 km/h
up to 300 km/h
up to 800 km/h
Where the ocean is over 6,000 meters (3.7 miles) deep, unnoticed tsunami waves can travel at the speed of a commercial jet plane, over 800 km per hour (500 miles per hour). Tsunamis travel much slower in shallower coastal waters where their wave heights begin to increase dramatically.
In which U.S. region are the tornadoes most frequent?
in the Mid Eastern states
in the Atlantic coast
they occur evenly throughout the U.S.
Tornado Alley is a colloquial term for the area of the United States where tornadoes are most frequent. The term was first used in 1952 as the title of a research project to study severe weather in areas of Texas, Oklahoma, Kansas, South Dakota, Iowa, Illinois, Missouri, Nebraska, Colorado, North Dakota, and Minnesota.
