Charney School of Marine Sciences at the University of Haifa following encompassing geoarchaeological research at the port of Caesarea.

These arc volcanoes, which account for about 10 to 25 percent of all volcanoes, are produced when one of the plates that make up Earth`s crust plunges beneath another plate, a process called subduction. http://www.physorg.com/news163684334.html Space & Earth Mon, 08 Jun 2009 12:54:21 EST news163684334 A massive underwater mountain discovered off the Indonesian island of Sumatra could be a volcano with potentially catastrophic power, a scientist said Friday. http://www.physorg.com/news162797255.html Space & Earth Fri, 29 May 2009 06:28:27 EST news162797255 (AP) -- Scientists found evidence of intense volcanic activity - including tremors, pools of lava and plumes of smoke - at two volcanoes near a major city in eastern Congo, and said some residents had fled for fear of an eruption. http://www.physorg.com/news160941775.html Space & Earth Thu, 07 May 2009 19:03:25 EST news160941775 (PhysOrg.com) -- A study into ash fallout from the biggest volcanic eruption in almost 20 years has shown that the impact of past eruptions is likely to have been significantly underestimated as so much of the evidence quickly disappears, Oxford University scientists report. http://www.physorg.com/news160836010.html Space & Earth Wed, 06 May 2009 13:41:25 EST news160836010 (PhysOrg.com) -- Science has unearthed the secret to what might have been alchemy at Oldoinyo Lengai volcano in Tanzania. http://www.physorg.com/news160834772.html Space & Earth Wed, 06 May 2009 13:20:37 EST news160834772 Scientists who have just returned from an expedition to an erupting undersea volcano near the Island of Guam report that the volcano appears to be continuously active, has grown considerably in size during the past three years, and its activity supports a unique biological community thriving despite the eruptions. http://www.physorg.com/news160754388.html Space & Earth Tue, 05 May 2009 15:00:13 EST news160754388 Up to 30,000 residents and tourists could be under threat from a newly discovered tsunami risk in the Caribbean, according to experts in disaster risk management. http://www.physorg.com/news159690411.html Space & Earth Thu, 23 Apr 2009 07:27:16 EST news159690411 Nearly 2,000 years after wiping out Pompeii, Mount Vesuvius is among the most closely monitored volcanoes in the world, its every shudder recorded. http://www.physorg.com/news159599107.html Space & Earth Wed, 22 Apr 2009 06:06:19 EST news159599107 The cameras watch her every move.
