Tsunamis leave ionosphere all wobble up

rss Acehtsunami Sep 17, 2010 I Earthquake Facts Info, Uncategorized. The signals of GPS satellites could be used to monitor tsunamis as they brush away the ocean. In the most detailed study to date of the effect, scientists have shown that even though open ocean tsunami waves are only a few centimetres high, they are great enough to create atmospheric vibrations extending all the way to the ionosphere, 300 kilometres up in the atmosphere. The finding, the researchers hope, could hugely improve tsunami early-warning systems.

Vanuatu was rattled by a major earthquake Tuesday afternoon sparking a tsunami warning in the region. The warning was down-ranged after a small wave reached Vanuatu’s capital Port Vila measuring only 23 centimeters high.

The United States Geological Survey’s (USGS) Earthquake Hazards Program said that the earthquake as a magnitude 7.3 quake, striking at 04:23:46 PM (Vanuatu time) at epicenter, with a depth of 35 km (21.7 miles), and 35 km (20 miles) West Nor West of Port Vila, Vanuatu.

Fears that a tsunami may pursue the quake caused locals to head for high ground. The tsunami threat has been reduced, although warning is advised as aftershocks measuring around 5 magnitudes are currently occurring in the region. At the time of writing there were no reports of injuries, however light damage was reported about Port Vila’s central business district.

Volcanic explosion causes Tsunami

rss Acehtsunami Aug 30, 2010 I Uncategorized.

Although relatively uncommon, violent volcanic eruptions represent also impulsive disturbances, which can displace a great volume of water and generate extremely destructive tsunami waves in the immediate source area. Volcanic disturbances can produce waves by the sudden displacement of water caused by a volcanic explosion, by a volcano’s slope failure, or more likely by a phreatomagmatic explosion and collapse and/or engulfment of the volcanic magmatic chambers.

Rotary wants GCSE books for tsunami victims

rss Acehtsunami Sep 01, 2010 I Uncategorized. The organizers of a charity book appeal are inviting teenagers who have completed their exams to donate old GCSE textbooks. The Rotary Club of Stamford is requesting for GCSE course books and children’s books to help victims of the 2004 tsunami, which hit Sri Lanka on Boxing Day.

The books will be issued to children on the island. The club has previously provided desks and other supplies to renovate or rebuild schools there. Rotarian Tony Wakefield, 75, of Little Casterton Road, Stamford, collected some of the books from the offices of the Citizen’s sister paper, the Mercury, in Sheep Market, Stamford, where we are collecting contributions.

The books will be handed first to a rotary club in Sri Lanka before being distributed. Before the end of the school term, some schools in Stamford including Malcolm Sargent Primary and Stamford Queen Eleanor School donated books they no longer wanted. The club has already sent about 10 tons of books following appeals in 2008 and 2009. If schools have lots of GCSE books, the Mercury, can arrange to have them collected.
