The Pacific island of Tonga hit by Tsunami© Provided by DW An undersea volcano off the coast of Tonga seen erupting in 2009The surge wave reached a height of 80 centimeters (31 inches), according to the New Zealand climate website Harukai Gulf Weather, citing sea level monitoring data. There is no information yet on property damage or casualties.

Images posted on social media from Tonga showed the tsunami breach the shoreline, and move into the town.

The US based Pacific tsunami warning center said tsunami waves measuring 2 feet in height were observed by sea-level gauges in the capital of the US territory of American Samoa, around 940 kilometers (580 miles) from Tonga.

Officials there initially issued a tsunami warning, and told residents to “immediately” evacuate to higher ground. The warning was cancelled shortly thereafter.

New Zealand, more than 2,000 kilometers away from the site of the eruption, has also issued a tsunami advisory.

New Zealand’s National Emergency Management Agency said parts of the country could expect “strong and unusual currents and unpredictable surges at the shore.”

Undersea volcano erupts

The eruption Saturday was the latest in a series from the undersea Hunga Tonga, Hunga Ha’apai volcano. Saturday’s eruption is the second in only two days.

A previous eruption on Friday sent plumes of ash and smoke into the air, with smoke clouds extending up to 20 kilometers (12 miles) into the atmosphere.

The volcano had showed some intermittent activity through December last year. On Friday, people were advised by officials to stay home and protect drinking water and resources.

Malawi: Optical Photography Leads Yolodani Primary School Learners in Chilomoni to Plant 1,000 Trees

Published

on

Renowned and fast growing youth-managed company, Optical Photography have embarked on a tree planting in response to the National Forestry Season by inspiring Yolodani Primary School learners to plant 1,000 trees.

Situated at the foot of Michiru Mountain forest in Chilomoni, Blantyre, learners at the school struggle to find shelter when it is hot because the premises is bare of trees that can provide fresh air.

Among trees that were planted included keisha, m’bawa, ntangatanga, nyowe, mombo, msabafumu and in her remarks, managing director of Optical Photography, Prudence Kasinja said they decided to embark on the tree planting exercise in order to help fight against deforestation and making sure that the country turns back to green like it was in the past years.

She added that they thought it wise to commence the exercise at Yolodani School after noticing that the campus had no trees around where teachers and learners could access some shade as well as protection of the class blocks from heavy winds.

“As one way of showing what good corporate citizens are supposed to do, we thought it wise to contribute something to the environment by planting these trees,” she said. “This is just the beginning of the exercise as we are planning to identify other areas where we’ll plant other.”

Chilomoni Zone Primary Education Advisor, Mirriam Mtukane applauded Optical Photography for the gesture, saying once they grow would really play a big role in making the campus to look attractive and provide shade for pupils.

She encouraged the learners, who had enthusiastically participated in the exercise, to take care of the trees to achieve a high percentage of survival.

The exercise was done in conjunction with Environmental Society of Malawi (WESM), whose environmental educational manager, Ausward Bonongwe commended Optical Photography for initiative, saying apart from providing shade for the pupils, the trees will also assist to mitigate soil erosion and conserve the environment.

“This is a great initiative and as WESM, we are proud of Optical Photography for considering to plant these trees,” he said. “We promise that together with the environmental and wildlife clubs, we will protect the trees.”

WESM is targeting to plant 2 million trees in Blantyre in 2023 alone.

Californium-252 Stone: An Expensive Element Said to be in Borno State

Published

on

If you do a quick Google search for the most expensive element in the world, one of the results will be californium-252 stone. 

According to Hamza Al-Mustapha, a former Nigerian Army major and intelligence officer who served as General Sani Abacha’s Chief Security Officer, in an interview with the Brekete family, he said a California 252 stone was discovered in Borno state and is worth $27 million per gram.

In his other remarks in the viral video, he said that the element was the cause of insecurity and Boko Haram in Borno and other resource-rich northern territories.

The 62-year-old Major, while speaking, said Nigerians should visit Google and search for the price of californium-252 stone.

This article will discuss what californium-252 stone is, what it is used for, where it is discovered, how much it costs per gram, and whether californium stone is actually found in Borno, Nigeria.

WHAT IS CALIFORNIUM-252 STONE?

Californianium, which has the chemical symbol Cf and atomic number 98, is defined on Wikipedia as a radioactive chemical element. At Lawrence Berkeley National Laboratory, which was then known as the University of California Radiation Laboratory, the element was initially created in 1950 by putting curium to an alpha particle bombardment (helium-4 ions).

It is an actinide element, the sixth transuranium element to be created through synthesis, and it has the second-highest atomic mass of all elements that have been created in quantities that are big enough to be seen with the unaided eye (after einsteinium). The institution and the American state of California were used as inspiration for the element’s names.

WHERE IS CALIFORNIUM STONE FOUND?

There is no such thing as Californium-252 in nature. As a result, it is typically created synthetically in labs for use in research and analysis procedures. Curium is used to produce Cf-252; a microgram of the substance is bombarded with alpha particles, resulting in the creation of 5,000 Cf-252 atoms.

HOW MUCH IS CALIFORNIUM PER GRAM?

Californium-252 can cost $27 million per gram, making it far more expensive than lutetium but less expensive than francium.

  • Californianium is reportedly utilized in microgram amounts, according to Andrew Tinker on Quora.
  • It would be incomparably valuable if you possessed something big enough to be called a “stone.”
  • Additionally, the substance is very radioactive, so if the stone is bigger than a fraction of a gram, terrible things will happen.
  • A 50 ton lead storage cask that can survive radioactivity of up to a gram is depicted in a lovely way on Wikipedia.
  • The hypothetical one gram cube would be around four millimeters on a side with a density of about 15 grams per cubic centimeter (supposedly, world production is closer to 1/2 gram a year).
  • That will be difficult to classify as a stone; it is more akin to a pebble or a grain of grainy sand.

DOES NIGERIA’S BORNO HAVE CALIFORNIUM?

Wikipedia states that only two locations produce Californium-252: the Research Institute of Atomic Reactors in Dimitrovgrad, Russia, and the Oak Ridge National Laboratory in the United States.

Californianium is a transuranic element that was created artificially and is not found naturally, according to the well-known website report on Nature. It has twenty known isotopes and is a late actinide. In an experiment that employed a 60-inch cyclotron to blast targets made of curium-242 with helium ions, Glenn Seaborg and colleagues made the first official identification of it in February 1950.

CONCLUSION

That is to say, there isn’t anything like to Californium in Borno State because it has never been discovered naturally and is only produced in little amounts each year—a few grams. In particular for petroleum exploration and gold and silver prospecting, Californium is employed in portable neutron emitters as well as in diagnostic and prospecting equipment. Cancer can also be treated with it.
