Hawaiian Village Catamaran Pier mid 50s by Kamaaina56

Offshore view from Waikiki’s Fort DeRussy looking ‘Ewa (more or less west here) towards the neighboring Hawaiian Village Hotel beachfront with several “Kaiser Pink” catamarans moored at the pier. A catamaran trip out to Diamond Head and back is always a perfect photo opportunity, not to be missed. Vintage but undated red-bordered cardboard mount “Kodachrome Transparency Processed by Kodak” slide produced between 1955 and 1959.

Mediterranean Sea magnitude 6.0 earthquake (1:51 AM, 14 May 2025) by James St. John

This seismogram is from the Archaggelos seismic station on the Island of Rhodes, south of mainland Greece. The noise is from a magnitude 6.0 offshore earthquake in the Mediterranean Sea, east of the Island of Crete. The quake hit at 1:51 AM, local time, on 14 May 2025. The epicenter was about 67.5 kilometers east of the town of Palekastro, Crete. The hypocenter was between 70 and 80 kilometers deep (below sea level). Shaking resulted from right lateral slip along a ~northeast-southwest striking fault zone or left lateral slip along a ~northwest-southeast striking fault zone. The quake occurred during a Moon-Earth-Sun alignment.

An earthquake is a natural shaking or vibrating of the Earth caused by sudden fault movement and a rapid release of energy. Earthquake activity is called "seismicity". The study of earthquakes is called "seismology". The actual underground location of an earthquake is the hypocenter, or focus. The site at the Earth's surface, directly above the hypocenter, is the epicenter. Minor earthquakes may occur before a major event - such small quakes are called foreshocks. Minor to major quakes after a major event are aftershocks.

Most earthquakes occur at or near tectonic plate boundaries, such as subduction zones, mid-ocean ridges, collision zones, and transform plate boundaries. They also occur at hotspots - large subsurface mantle plumes (Examples: Hawaii, Yellowstone, Iceland, Afar).

Earthquakes generate four types of shock waves: P-waves, S-waves, Love waves, and Rayleigh waves. P-waves and S-waves are body waves - they travel through solid rocks. Love waves and Rayleigh waves travel only at the surface - they are surface waves. P-waves are push-pull waves that travel quickly and cause little damage. S-waves are up-and-down waves (like flicking a rope) that travel slowly and cause significant damage. Love waves are side-to-side surface waves, like a slithering snake. Rayleigh waves are rotational surface waves, somewhat like ripples from tossing a pebble into a pond.

Earthquakes are associated with many specific hazards, such as ground shaking, ground rupturing, subsidence (sinking), uplift (rising), tsunamis, landslides, fires, and liquefaction.

Some famous major earthquakes in history include: Shensi, China in 1556; Lisbon, Portugal in 1755; New Madrid, Missouri in 1811-1812; San Francisco, California in 1906; Anchorage, Alaska in 1964; and Loma Prieta, California in 1989.
