In many cases you will hear a low noise from the wind. You may hear the sound of trees snapping and glass shattering. If you are unlucky, and the tornado is a strong one, the house may collapse above you, though this is unlikely. In rare cases the house may by removed from its foundation, exposing people in the basement to wind and debris.
Whether or not a bathtub is porcelain probably would not make a significant difference during a tornado. The type of porcelain from which bathtubs are made would not break in the same way that porcelain dishes can shatter. The important factor is the depth of the tub, and whether the sides are high enough to provide protection from the wind force and from flying objects.
During a tornado, the air pressure can drop significantly. It is not uncommon to see pressure drops of 10-20% below normal levels, which can correspond to pressures around 28 to 30 inches of mercury (950-1010 millibars).
The explosion would probably disrupt the tornado. However, the effects of the blast and fallout would likely be worse than anything the tornado could do. Even then, the parent thunderstorm may still go on to produce another tornado.
A tornado with the fastest known wind speeds would be classified as an EF5 tornado on the Enhanced Fujita Scale. EF5 tornadoes have estimated wind speeds of over 200 mph (322 km/h) and cause extreme damage.
It doesn't: that is a myth. The idea stems from the fact that the pressure inside a tornado is very low and the higher pressure inside a house will cause it to explode unless windows are open to relive pressure. The truth is that the winds and debris of a tornado are what cause damage, not the pressure difference. Even in a relatively weak tornado that will cause only moderate damage the windows are likely to break anyway. In fact, in the case of a weak tornado or indirect hit that would not break windows, leaving them open allows strong winds to enter the house and cause damage on the inside. The pressure drop in a tornado is not great enough to cause damage and even then, houses are not airtight, and pressure can equalize on its own fairly quickly. The greatest pressure drops come in the strongest tornadoes, which can easily tear apart a house with their winds regardless of any pressure difference within the structure.
You would go to the most sheltered area of the basement, away from any windows or outside doors.
It depends on the strength of the tornado, but it is not as safe as a fully underground basement. In most cases it would be safe, especially if you can get into a room that is in the underground portion of it.
Any part of a home can be impacted by a tornado, depending on how strong it is. A weak tornado will probably not damage more than the exterior. The basement is the least likely part to be affected, but an EF5 tornado could easily remove a house from its foundation and expose the basement to the winds.
The basement would be best. Stay away from windows. If you don't have a basement, you should go into a bathtub and pull a matress over you. You could also go beneath a staircase.
Tornado alley in America :P
Not really, but probably somewhat safer juxtaposed to being on the ground. If a tornado is coming you should not be outside. Take cover in a sturdy house or building, preferably in the basement if it has one.
If you have a basement that would be your best bet. Or find a small closet with no windows or around any window. Some homes have a closet underneath the stairs and that would be your best bet if you home lacks a basement.
if you have a basement you may be safe in there or in a underground shelter would also keep you safe from the violent storm
It is possible, but there is a good chance you would not survive the experience.
Climate change may afftect tornado activity in some regions, but exactly how is uncertain. Some areas would experience more tornadoes and some would experience fewer.
The corner of the basement or a small central room would be the safest place Since a flying object could possibly crash into a window, and broken glass itself can cause a serious injury don't stand too close to a window.
You cannot accurately identify a tornado based on the sound. That said, if you can hear a tornado it is probably already very close. You must take cover immediately. Heat to you basement or an interior room on the lowest floor of your house.
