Rita Krill, 53, of Naples, Fla., got a little more than she bargained for while shooting a severe thunderstorm in her backyard Oct. 5.
“It was about 100 feet from my yard,” Krill said. “I was out there videoing it. My puppy was out there. She usually doesn’t flinch too much at storms. She’s used to it. And then, boom, the lighting struck and you could obviously hear my reaction.”
Krill can’t believe she captured the lightning striking the up-lighting in her next door neighbor’s yard on camera, which blew out the light and caused large electrical sparks.
What she called a “fireball” in the video she uploaded to YouTube that night.
“What’s incredible is what are the chances of this happening just as I was panning that direction?” Krill asked. “My next door neighbor has up-lighting on the trees next door in her yard. It completely decapitated the lighting unit itself. It exploded. The tree wasn’t charred or burned. It just shaved it clean.”
Krill says Naples is the lightning capital of North America, but she’s still fascinated by the thunderstorms because she’s originally from California and not used to that kind of severe weather.
The U.S. seismologists said that any wave generated by the quake would be expected to hit Indonesia first.
The experts said the quake had a depth of 34 kilometers (21 miles) and hit at 8:47 pm (1247 GMT) some 139 kilometers east of the city of Sulangan, eastern Samar.
The tsunami warning was issued for the Philippines, Indonesia, Papua New Guinea and other islands in the Pacific including the U.S. state of Hawaii.
“An earthquake of this size has the potential to generate a destructive tsunami that can strike coastlines in the region near the epicentre within minutes to hours,” the center said.
Recently I read Frederick Forsyth’s Dogs of War where there was a passing reference to L’Agulhas, Cape of Good Hope.
I wanted to find out more.
Here it is.
Atlantic and Indian Ocean Meet
”
From the coast of the Antarctic continent northwards, along the meridian of 20°E to Cape Agulhas (34°50’S – 20°00’E), the southern extremity of the Republic of South Africa, in Africa (the common limit with the South Atlantic Ocean).
So those who travel to Cape Point, or the Cape of Good Hope, in the hope of seeing the confluence of two oceans… you need to travel a little further south. And for those who still try to pursue the debate for commercial reasons, the Hydrographic Office of the South African Navy accepts the findings of the IHO regarding the common boundary of the Atlantic and Indian Oceans and that they apply these findings in full in their products. The Department of Oceanography at the University of Cape Town also accepts and applies the 20°E dividing line.
The most common misunderstanding behind the controversy is the erroneous assumption that oceans and currents are synonymous.
The Agulhas Current brings warm water from the subtropics down the East Coast of South Africa. From the region of East London, because of the widening of the continental shelf, the current flows further offshore and the coastal waters become cooler. On the West Coast, the water is chilled by the north-drifting, cold Benguela Current. When the wind blows the surface waters offshore, deep water, which is rich in nutrients, swells up to replace it.
The changes in temperature along the coast bring about changes in marine life. One obvious example, which is there for all to see, is the prolific kelp (Ecklonia maxima) forests which prefer the colder, nutrient rich waters of the West Coast. It is significant to note that the kelp grows all the way from the West Coast, past Cape Point in an easterly direction, only as far as Cape Agulhas. It can therefore be safely assumed, and can be borne out by physical tests, that the water to the west of Cape Agulhas is predominantly colder than to the east. This fact supports the argument that the dividing line between the warm and cold waters is more often at Cape Agulhas than anywhere else.
