Alaskan Earthquake of 27 March 1964: Remote Seiche Stimulation
Science (New York, N.Y.)
|July 17, 1964
Summary
Unusual 6-foot waves along the Texas and Louisiana coasts during the 1964 Alaskan earthquake were likely caused by seismic wave resonance. These water waves matched the seismic wave periods, indicating a direct connection.
Area of Science:
- Geophysics
- Oceanography
- Seismology
Background:
- The 1964 Alaskan earthquake generated significant seismic waves.
- Unusual wave activity was observed along the Gulf Coast following the earthquake.
Purpose of the Study:
- To investigate the cause of unusual water waves observed on the coasts of Louisiana and Texas after the 1964 Alaskan earthquake.
- To determine if seismic waves influenced the observed water wave phenomena.
Main Methods:
- Analysis of tide gauge data from Freeport, Texas.
- Comparison of water wave periods with seismic surface wave periods.
Main Results:
- Significant wave activity up to 6 feet was recorded at Freeport, Texas.
- Observed seiche periods in local channels closely matched seismic surface wave periods.
- Evidence suggests water waves were generated by and resonated with seismic waves.
Conclusions:
- The study concludes that seismic wave resonance likely generated the observed water waves.
- The findings highlight a potential mechanism for seismic wave-induced coastal water disturbances.

01:20Elastic Strain Energy for Shearing Stresses
As discussed in previous lessons, strain energy in a material is the energy stored when it is elastically deformed, a concept crucial in materials science and mechanical engineering. This energy results from the internal work done against the cohesive forces within the material. When a material undergoes shearing stress and corresponding shearing strain, the strain energy density, which is the energy stored per unit volume, is calculated. Within the elastic limit, where the stress is...
01:16Shock Waves
While deriving the Doppler formula for the observed frequency of a sound wave, it is assumed that the speed of sound in the medium is greater than the source's speed through it. When this condition is breached, a shock wave occurs.
When the source's speed approaches the speed of sound, constructive interference between successive wavefronts emitted by the source occurs immediately behind it. Initially, scientists believed that this constructive interference would result in such high pressures...
