Taupo Volcanic Zone

The Taupo Volcanic Zone is a highly active volcanic V shaped area in the North Island of New Zealand that is spreading east -west at the rate of about 8mm per year. It is named after Lake Taupo, the flooded caldera of the largest volcano in the zone.

Activity

There are numerous volcanic vents and geothermal fields in the zone, with Mount Ruapehu, Mount Ngauruhoe and White Island erupting most frequently. The zone's largest eruption since the arrival of Europeans was that of Mount Tarawera in 1886, which killed over 100 people. Early Maori would also have been affected by the much larger Kaharoa eruption from Tarawera around 1300 CE.

The last major eruption from Lake Taupo, the Hatepe eruption, occurred in 181 CE. It is believed to have first emptied the lake then followed that feat with a pyroclastic flow that covered about 20,000 square kilometres (7,722 sq mi) of land with volcanic ash. A total of 120 km³ (29 cu mi) of material is believed to have been ejected, and over 30 km³ (7.2 cu mi) of material is estimated to have been ejected in just a few minutes. The date of this activity is known since the ash expulsion was sufficiently large to turn the sky red over Rome and China (as documented in Hou Han Shu).

TVZ

Television Zanzibar, also called TVZ, is a television station in Zanzibar, Tanzania. It was the first colour television station south of Sahara. It is a state owned broadcasting station which produces and transmits development-oriented programs.

History

TVZ was inaugurated in 1973 by the first president of Zanzibar, Sheikh Abeid Amani Karume, using PAL system, and broadcasts in Swahili and English. It carries local and international programmes. The station is located at Karume House building. The building was renovated in 1972 when it was turned into a TV studio and was meant to be temporary. Because of financial constraints the government could not put up another TV studio structure to date.

Mission

The mission of Television Zanzibar is information, education and entertainment to the public taking into consideration their interests. Since its inception the motto for Television Zanzibar has remained "ELIMU KWA TELEVISHENI" ("Education through Television"), the idea which stemmed from Sheikh Abeid Aman Karume.
