hazards and disasters

Rotating supercell over the U.S. Great plains. I can’t tell if this is actual video or if this artists works to animate still frames, but I think some of their clips are the latter.  Almost time for tornado season to start moving up to the central U.S.

Why Do the Impacts of Hurricanes Differ in MEDCs and LEDCs?

Why the effects of tropical revolving storms are less damaging in richer areas:

  • High-quality services so there are enough medical supplies and well-equipped hospitals to deal with the injured.
  • If richer areas require foreign aid to cope with the aftermath it can be brought quickly to the affected area as they have a better infrastructure.
  • People are prepared, sometimes rehearsed, and know what to do in the emergency.
  • Good water supplies, which if disrupted, can be quickly repaired. This stops the spread of water-bourne diseases in the aftermath of the storm.
  • There are experts readily available to give advice and assess the situation.
  • There are well-developed plans for dealing with the emergencies and they are rehearsed; which means there are no delays in bringing emergency services to the area.
  • Housing is built using modern methods and high standards, and is storm-proof. 
  • Communications are good: access roads are well maintained and in remote areas people have radios.

Storm chaser prepping for the 2017 season shared this magnificent video of a 2016 tornado they spotted in Kansas.

Disaster on Honda Point

Wreck of U. S. destroyers Sept. 8, 1923. Honda Rocks, Santa Barbara Co., California.

In the U.S. Navy’s largest peacetime loss of ships, seven destroyers ran aground on the rocks off Honda Point on the evening of September 8, 1923.  Twenty-three sailors died in this disaster.   Two other ships were grounded, but were able to break free.  Five other ships in the squadron were able to avoid the hazard.

Falcon 9 suffers catastrophic anomaly ahead of static fire; Amos-6 booster and satellite destroyed.

At 9:07 am EDT, SpaceX’s Falcon 9 rocket suffered an anomaly at SLC-40, minutes ahead of today’s scheduled hot fire test. While specific details are unclear as of yet, SpaceX founder Elon Musk stated that the vehicle was undergoing propellant loading, and that the anomaly occurred around the second stage’s Liquid Oxygen tank.

In the video above, taken by Mike Wagner of US Launch Report, Falcon 9 is seen in the final minutes of propellant loading. An explosion is seen originating in the lower portion of the second stage, which is where its Liquid Oxygen tank is located. A few moments later, the rocket’s payload fairing - with the Amos-6 satellite tucked inside - is seen falling to the ground.

The 45th space wing out of Patrick Air Force Base, which operates Cape Canaveral Air Force Station, stated that no injuries have been reported by SpaceX or any other launch company.

Amos-6 was scheduled for launch between 3 and 5 am EDT on Saturday, September 3. Once the area is clear of hazards, a disaster response team will asses damage to SLC-40 and the surrounding area. While an investigation will have to occur before the Falcon 9 can fly again, it is unclear how quickly LC-39A can be activated if the rocket is ready to fly before the pad is.

Amazing captured video of a rockfall in the Swiss Alps. This rock has been monitored for years due to being unstable and movement was detected on it beforehand, causing the valley below to be evacuated.

Earthquake prediction

This is on the BBC Geography Bitesize website

Earthquakes are not as easy to predict as volcanic eruptions. However, there are still some ways of monitoring the chances of an earthquake:

  • Laser beams can be used to detect plate movement.
  • A seismometeris used to pick up the vibrations in the Earth’s crust. An increase in vibrations may indicate a possible earthquake.
  • Radon gas escapes from cracks in the Earth’s crust. Levels of radon gas can be monitored - a sudden increase may suggest an earthquake.

These all highlight the major problem with trying to predict earthquakes: it is, overall, impossible. You can attempt to predict where and when they are going to happen, but - in comparison to other hazards, such as hurricanes - it is not possible.

Predicting earthquakes spatially (where they are going to happen) is possible in that you can say that they will occur around plate boundaries (I know, I bet you didn’t expect that), but predicting them temporally (when they are going to happen) is, currently, not possible.

The above techniques go some way to helping to predicting earthquakes, but none of the techniques are 100% reliable.

Imagine Bucky trying to convince JARVIS to loan him one of Tony's Iron Man suits.

Bucky is standing outside the glass door into Tony and Bruce’s designated “Science Bros” laboratory (“It’s a fire hazard, a disaster waiting to happen” is what the rest of them call it). Tony’s gone for the weekend, so Bucky’s decided it’s as good a time as any to ask the computer if he could go for a ride.

“Hey, um, JARVIS?” he speaks quietly to a small microphone on the wall near the door.

“Yes Mr. Barnes?” the AI asks just a little too loudly.

“No, shh, I think Pepper’s around.”

“Ms. Potts is on the fourth floor presently, in a meeting. Would you like me to alert her-“

“NO!” he hisses into the microphone. “Definitely not. I was- I wanted to know if you could let me into the lab.”

“Dr. Banner and Mr. Stark have explicitly requested that nobody be allowed into the laboratory.”

Bucky frowns, then tries to ham it up. “Yeah, but it’s me. They love me. Plus, how much harm could I do? I’d never hurt a fly.”

“Mr. Barnes there are several instances that would beg to differ,” the computer says. Bucky swears there’s almost humor in its voice, but that’d be ridiculous. It’s a machine. Machines don’t have humour now, do they?

“Like what?” he asks, a little curious to see just how much it knows.

“Most recently, twelve minutes ago when you saw a spider, became very tense, then proceeded to hit it violently and well beyond the point of death with a rolled-up magazine.”

Bucky snorts and slumps against the wall. “But other than that. It’ll be fine, I promise.”

“Mr. Barnes, I cannot and will not allow you to enter the laboratory.”

“Then just fly one of the suits out here!” Bucky demands. “Let me fly around in an Iron Man suit!”

“Mr. Barnes, you do not have clearance to fly the Iron Man suits,” JARVIS insists.

“I won’t go very far. I’ll just fly around the neighbourhood.”

“Mr. Barnes.”

“I won’t go up more than… a thousand feet.”

“Mr. Barnes.”

“I’ll make sure there isn’t a scratch on it! I’ll even put it through a car wash if it needs after!”

“Mr. Barnes!” the computer says.

Bucky takes a deep breath, then tries again. “Please, please, pretty please? I’ll- I’ll… I’ll break the door down if you don’t let me!”

“In which case the Iron Man suits’ interfaces will lock, as I control those too.”

“Aw, c’mon!” Bucky whines. Then he waits a second. “Well what if it’s just for five minutes-“

“I’m afraid I may have to call Ms. Potts.”

“No! Don’t do that! She scares me a little.”

“I’m afraid you can’t use the Iron Man suits, Mr. Barnes.”

“Fine,” Bucky straightens up and looks indignantly at… wherever the camera is that JARVIS uses. “Back in my day, technology was here to help us…”
