That is dependant on the temperature of the region and moisture of the air. Hurricanes feed of moisture and heat to fuel them, in some cases the answer is yes while others can survive for days
A tornado will typically, though not always, last less than 10 minutes. On rare occassions a tornado may last for over an hour. A hurricane, by contrast, lasts several days.
Yes. In fact, tornadoes that last and hour or more are rare. Most tornadoes last less than ten minutes, and many last only a few seconds.
A tornado can last up to a few minutes or an hour, sometimes more. Some tornadoes last just a few seconds. Strong tornadoes usually last longer because they have more energy and are less easily disrupted.
No. Most earthquakes last less than a minute.
No. An earthquake would never last more than an hour. Most last less than a minute. The 1989 earthquake lasted 15 seconds.
On the Beaufort Scales the definition of one less than a hurricane is a violent storm.
Usually, yes. The vast majority of tornadoes last less than an hour, with a typical tornado lasting no more than 10 minutes. Occasionally, a tornado will last for more than an hour, sometimes much more. At least one tornado is believed to have lasted for more than 3 hours. Such long-lived tornadoes are usually rather strong.
Tornados only last an average of 10 to 15 minutes. Some can last seconds.
A hurricane has low pressure, usually less than 995 millibars.
Hurricane Rita formed a little less than a month after Hurricane Katrina.
Less than a month.
They are in no way 'less violent'. They may seem it because tornadoes traval faster than a hurricane but, hurricanes last much longer and take more lives than a tornado does.
