1988, 1993, 2023. -- ?? Did you know that in addition to the magnitude 5+ earthquakes (with epicenters on mainland-1993 & 2023), Jamaica also recorded a magnitude 5+ in 1988? -- Our scouring of literature ( Ahmad, 2001; Wiggins-Grandison, 2005) highlighted some interesting findings. When we combined their findings with ours, (surface earthquake expression via Google Terrain & 1961 Aerial Photos), what we saw was scientifically interesting. We share these interesting findings & considerations in this video (full on YouTube). ?? Please note, the content is Seismo-Geology heavy. We did our best to keep it understandable for the general public. -- ?

1907 Earthquake Monument: The 1907 Earthquake Monument in Jamaica stands as a poignant reminder of the devastating earthquake that reshaped the island’s history and urban development. Erected to commemorate the tragic event that struck Kingston and surrounding areas, this monument encapsulates the profound impact on Jamaica’s architectural and real estate landscape. Following the earthquake, Jamaica faced a period […] The post 1907 Earthquake Monument first appeared on Jamaica Homes.

Using Augmented Reality to imagine the flood caused by the Ri?ihuazo in Valdivia, after the 1960 earthquake. After the earthquake, the drainage of Ri?ihue Lake was blocked by 3 big landslides in a gorge, acting as dams. Several cities including Valdivia, located downstream the lake, were under danger due to a possible "dam break" once the water would reach the top of the dams. This indeed happened after the 1575 earthquake (with a dam break in April 1576). Engineers and workers, led by Raul Sáez, worked for several weeks carving a river/channel next to the landslides. While the dam break was prevented, Valdivia still faced a rise of the river for several days, known as Ri?ihuazo. Full details in the movie "La Respuesta" (with subtitles) https://lnkd.in/e7VYeZ88

Today marks the 13th anniversary of the Van Earthquake. We analyzed this significant event in detail during our #GlobalSeismology class. Learning from the past helps us build a more resilient future. ???? https://bit.ly/4hjVVTo #Earthquake #Seismology #DisasterManagement #VanEarthquake

Is it necessary to consider an earthquake for designing a G+0 building?

Thoughts!? ???? Greg discusses the two structures that carry I-5 across the Columbia River. The southbound structure is the newest, built in 1958, while the northbound structure is the original crossing. The bridges are jointly maintained by ODOT and WSDOT, but the northbound bridge is 107 years old and functionally obsolete, though still safe to cross. However, there are concerns about its ability to withstand an earthquake. Let us know what you think about the bridge!

A 7.5 earthquake hit Taiwan yesterday and footage shows the Taipei 101 skyscraper shaking. The 1,670ft building famously has a 703 ton steel ball hanging between the 88th and 92nd floors, which acts as a “dampener system” to reduce building sway by 30-40% during earthquakes and typhoons. This video explains how the system acts like a pendulum to prevent structural damage. The engineering marvel is a passive dampening system, which means it doesn’t require an outside power source but is “powered by natural movement of the building.” via Alvin Foo #MaritimeIndustry?#Shipping?#MarineTechnology?#MaritimeInnovation?#OceanTransportation?#PortsAndTerminals?#MarineEngineering?#MaritimeLogistics?#MaritimeTrade?#NavalArchitecture?#Seafarers?#MaritimeSafety?#Oceanography?#MaritimeLaw?#MarineEnvironment?#MaritimeEducation?#MaritimeHistory?#Shipbuilding?#MaritimeEconomics?#MaritimeSecurity?#CruiseShipDepartures?#ThrusterControl?#MaritimeMastery?#JourneyOfDiscovery?#PassionForTheSea
