How Big Was The Recent Sumatra Quake

How Big Was The Recent Sumatra Quake




The recent Sumatra earthquake displaced a section of the ocean floor over 700 miles long and 10 miles wide, nearly 100 feet upward. An equal amount of ocean water on the order of 135 cubic miles was moved violently upward and outward. This massive plunger type motion created huge tsunami waves that brought devastation to coastlines 4,000 miles away. On a map of the world it is hard to gain a sense of how big this thing was. So, on a map of the United States AccuWeather.com has placed the entire length of the fault segment that shifted. As you can clearly see, it is huge covering a distance from Chicago all the way to Denver or from New York City all the way to St Louis.



A devastating earthquake occurred in the Indian Ocean just off the coast of Sumatra 12-26-04. The quake, rated at a magnitude 9.0, is the most powerful recorded worldwide since 1964. Taking place at a depth of 6.2 miles below the surface of the ocean, the quake caused a severe deformation in the seafloor which displaced 135 cubic miles of water upward and outward much like what a massive plunger would do. This created massive waves called tsunamis that moved outward in all directions bringing devastation and even death to coastlines up to 4,000 miles away.

Phel Trojan

Security firm Symantec Corp. is warning users of a newly discovered Trojan horse named Phel -- an anagram of the word "help" -- that attacks Windows XP. The Trojan is capable of remotely controlling a user's system even if the latest Windows XP Service Pack, SP2, has been installed.

The Trojan, distributed as an HTML file, attempts to exploit a vulnerability in Internet Explorer's HTML Help Control component in all versions of Windows. The vulnerability was discovered in October.

Microsoft is actively investigating new public reports of a criminal attack, according to a Microsoft spokesperson.

For the exploit to succeed, an attacker would need to entice a user to visit a malicious Web site and then place the Trojan on the user's machine. If the Trojan executes successfully, potentially malicious software could be downloaded and run on the user's system, the spokesperson said.

Microsoft is working to forensically analyze the malicious code in Phel and will work with law enforcement agencies to identify and bring to justice those responsible for the malicious activity, he said.

"Microsoft is taking this vulnerability very seriously, and an update to correct the vulnerability is currently in development," the spokesperson said in an e-mail message. "We will release the security update when the development and testing process is complete, and the update is found to effectively correct the vulnerability."

Microsoft said customers in North America who think they may have been affected can receive help with security update issues or viruses at no charge by calling Product Support Services at 866-727-2338. International customers can receive the same level of support online at http://support.microsoft.com.

Customers in the U.S. who believe they have been attacked should contact their local FBI office or post their complaint online at www.ifccfbi.gov. Customers outside the U.S. should contact the national law enforcement agency in their country.
