U.S. spy satellites aid Katrina recovery

By Reuters
September 1, 2005



WASHINGTON– U.S. Spy satellites have been called into service to help federal emergency officials cope with the devastating aftermath of Hurricane Katrina, officials said Wednesday.

The little-known National Geospatial-Intelligence Agency, which analyzes satellite images for the espionage community and combat troops, has provided scores of images of hard-hit areas, including New Orleans, before and after the storm struck.

The agency said one of its main aims is to survey damage to regional transportation for the Federal Emergency Management Agency, which can then use the data to organize relief efforts. FEMA officials could not be reached for comment.

"NGA can determine the overall damage to a transportation network infrastructure--what bridges are out, what roads are flooded--which is critical for FEMA getting relief supplies into the disaster area," said NGA spokesman Stephen Honda.

The Pentagon agency, previously known as the National Imagery and Mapping Agency, joined the hurricane effort on Friday when it gave FEMA 100 graphic images showing the location of hospitals, police stations, highways, and schools in the storm's path along the Gulf coast.

After the storm, the agency gave FEMA its first cloud-free satellite image of downtown New Orleans. The image was snapped by a commercial satellite.

NGA, which once concentrated wholly on overseas targets, has become more involved in domestic security and relief efforts since the September 11, 2001, attacks on Washington and New York.

NGA analysis has aided security efforts at large public events including the Super Bowl and the 2004 presidential conventions. Its satellite imagery has also provided assistance to Asian tsunami relief efforts and in fighting forest fires.

Sonic 'Lasers' Head to Flood Zone

EDWARDS AIR FORCE BASE, California – Air-raid sirens, Frank Sinatra songs and Muhammad Ali trash talk blared over the Southern California desert in a demonstration of new acoustic technology for crowd control and disaster communications.

In mid-90's morning heat at Edwards Air Force Base, HPV Technologies and American Technology demonstrated prototypes of non-lethal sonic devices for a group of military and law enforcement guests, including representatives of the U.K. Home Office. . .

. . . When a subject is at close range in MAD's sonic path, and it is set to high volume, the sound can be excruciating.

The ability to broadcast instructions or alerts at great distances with minimal distortion could be useful for authorities and rescue crews in areas where other communications systems are unavailable.

American Technology is donating four devices -- three MRADs (medium-range acoustic devices) and one LRAD (long-range acoustic device). The four devices will be shipped out Friday to a Marine military police unit that is deploying to the Gulf States area for disaster-relief efforts.

"We are donating the use of one of our most powerful prototypes, LTPMS-2, for use in Mississippi as soon as possible, because the governor of that state said that the biggest problem they have right now is the fact that they have no communications infrastructure to get information or instructions out to people," he said. "They can very easily put this on a truck and send sound out for a minimum of at least a mile in either direction.". . .


. . . While both manufacturers stressed that their devices were designed primarily to hail, warn or communicate, other sonic technologies have been used by governments as a less pleasant way to disperse crowds.

Vehicle-mounted devices were used by Israeli authorities to scatter groups earlier this year, when Palestinians and Jewish supporters gathered to protest Israel's West Bank separation barrier. Dubbed "The Scream" by the Israeli Army, the device sends out streams of noise in intervals of about 10 seconds. The specific sonic frequencies chosen affect the inner ear, creating dizziness and nausea in human targets.

In a report, AP quoted an unnamed Israeli military official as saying the device emits a frequency that targets the inner ear, can cause damage with exposure for several minutes at close range, and compels humans nearby to leave the area. Exposure for minutes at close range could cause hearing damage. Information about longer-term exposure effects at long distances has not been publicly disclosed.

Both HPV's MAD and American Technology's LRAD are said to excel in mid- to higher-frequency sound ranges where sounds like sirens, alert "chirps" and human speech reside. Products from both companies could be used, at high volume, to harm subjects who do not comply with commands.

Devices from both companies vary in price, depending on quantity sold, size and which agency is purchasing -- but generally range from $10,000 to $75,000 per unit.

I hope they were truly meant for Search & Rescue, and not crowd control.
