However, tagged whales expended a little less energy searching for food and emitted fewer clicks associated with homing in on prey during the seismic
surveys than they had before those surveys commenced, says Miller.
Romer launched the second seismic
study under pressure from Los Angeles County Supervisor Gloria Molina, although many school officials and scientists conceded that the probability of reaching a definitive answer is remote.
He does note, however, that action plans for reducing earthquake hazards of existing buildings are already written with the support of FEMA, the lead agency for the National Earthquake Hazards Reduction Program (NEHRP), and include methodology for rapid visual screening of buildings for potential seismic
The company has solved the two major issues hindering the wide adoption of wireless seismic
recording systems -radio transmission bandwidth and battery life.
That velocity is so great that the seismic
waves form an intense pressure pulse that's analogous to a sonic boom in the air.
In July 1999 the DTSC asked the district to conduct a seismic
study because efforts to remediate gas and oil problems can be impacted by earthquake issues.
Venture's use of 1DFM will enable the company to further enhance its modeling services and provide clients a comparison of real and synthetic seismic
data to make geological inferences from the data.
The image clearly distinguishes between broad, sediment-rich areas where the seismic
waves traveled at slower-than-average speeds, such as the Los Angeles Basin, and rockier regions, such as mountains, where the waves traveled more quickly.
Goldberg said she has pressed hard for more funds for the historic park for several years, believing her district had been shorted in seismic
Reservoir Exploration Technology ASA (RXT) is a marine geophysical company specializing in multicomponent seismic
Geological Survey in Denver, a quake of similar force occurs in the New Madrid seismic
zone, on average, once every 500 years.
Other investigations, particularly analyses of seismic
waves traveling through and just under those landmasses, have indicated that the continents may be up to 400 km thick.
Keeping with tradition of developing leading edge technology to derive rock properties from seismic
data, the major development topics of LFP2 are:
The remaining 130 sensors would listen for seismic
vibrations that might have been generated by underground explosions.
The ability to propose the well resulted from the company's evaluation of acquired 3-D seismic
data which has generated 19 drilling locations in addition to RAM's existing four proved undeveloped drilling locations.
