What is the most dangerous natural disaster?

[rj144]

I think you would be least likely to survive a tsunami. Watch some of the videos on YouTube of the big ones. It’s pretty astounding.

Mimas far as what kills the most, it’s not a contest. Remember the tsunami back in 2004 in Indonesia? It killed like a quarter of a million people. Then there was the one in Japan 8-9 years ago that killed almost 20,000 people.

Is Saturn's moon that deadly it causes tsunamis?

Landslides. They can come from earthquakes, fire, drought, hurricanes, etc.

 

[Wrath of Foamy]

Earthquakes cause Tsunamis.

So I voted Earthquakes.

 

[Sir Galahad]

That was a particularly awful hurricane, so much destruction. Did it damage any of your home or cars?

I'm alive. Fortunately none of my friends died either. @HI SCOTT NEWMAN

um. Chuck for 500

The sun supernovas.

 

[Law Talkin’ Guy]

Well the 2004 tsunami killed something like 290,000 which has to be close if not the record holder for deadliest single natural disaster so I guess that.

A supervolcano could wipe out millions or potentially billions but the eruptions we've seen in our lifetime have been pretty manageable. The Tsunami that hit asia a few years ago wiped out 225,000 people in a dozen countries in a few hours maybe minutes. Most wars don't put up those kinds of numbers.

underwater landslide, usually caused by an earthquake, volcanic eruption. usually caused by an earth quake.

What makes you think that an earthquake causes a volcanic eruption? It's almost always the volcanic eruption causing earthquakes. There are often local earthquakes prior to a volcanic eruption caused by magma moving toward the surface. A large earthquake could trigger an eruption but not if the pressure isn't already in the system.

As I posted earlier, Tsunami are easily avoided by not living on the coastline.

Pretty much, the idea they'll hit the US coast at giant size was really only talked up by a small number of people in order to appeal to the media, in reality they'd have dissipated down to a relatively small size by then. The famous Alaskan landslide(well to geographers anyway, its always the case study for this kind of thing) from the 50's shows you how quickly wave size decerases even in a small lake...

What made the Indian Ocean quake so deadly and far reaching was that you had a massive area of sea floor jacked up, almost 1000 miles along the fault.

Tsunami in the deep ocean may not be more than a slight swell. It is a wave of energy being pushed through the water. It's when that energy nears a coastline and gets confined by the slope of the ocean floor that it gets pushed into a wave or more often like a rising tide that just keeps pushing more water ashore.

Of those listed, its definetly volcano.

Floods and cyclones have killed more though... some are way more.

Well hell, if you are on ISS you can avoid all kind of disasters,

 

[GSP_37]

What about tornado that picks up your brick house and dumps it somewhere?

Check this out. @HI SCOTT NEWMAN @Clementine @BroRogan @BFoe

moon sized meteor hitting us?

Voted for the cano.

Still though from a landslide, even a giant one as mentioned your going to have the wave dissipate as it spreads, the idea La Palma collasping is going to hit the east coast of the USA with a megatsunami is not widely supported, its more one guy hyping it because it naturally draws media interest and some TV docs were made about it.

The 2004 tsunami was able to have a big effect as far as Sri Lanka because a massive area of sea floor was jacked up, the wave wasn't just spreading from one point but from an area of sea floor almost 1000 miles long. That was I believe in terms of total energy the largest earthquake since measurements began, some higher local results have happened but not over the same area.

You don't seem to understand that the wave keeps going until it strikes land where the energy is dissipated. There was a report from an old Spanish mission in California that a wave deposited a boat near the mission that was on a hill high above the ocean. There is evidence that a landslide occurred in Hawaii at the correct timeline to have pushed a wave to California. That's 2500 miles. There is evidence along the west coast that there have been many large waves that came ashore in the past. A rise in the water level of 10 feet could be disaster for Florida, especially the Southern part that isn't very high above sea level. La Palma is 3700 miles from Florida but a look at the geography indicates the wave would be directed to the East coast of the US.

Most of Florida is well below 50 feet in elevation.

Here is a chart I found of the highest waves.

The largest waves were higher because they were in confined spaces.

Still, the death toll from earthquakes and tsunami will be but a pittance compared to the devastation of a Supervolcano that would endanger the lives of almost every human on Earth.

Even with the widespread death toll of the 2004 Tsunami, the 1976 Earthquake in Tangshan China killed more people when at least 242,000 died and some claim it could be three times that many.
