This earthquake alerted State and Federal officials that a facility was necessary to provide timely and effective tsunami warnings and earthquake information to the coastal areas of Alaska.
Congress provided funds in to construct two new observatories and establish a tsunami warning system in Alaska. The first observatory constructed was at the U. The City of Palmer, in the Matanuska Valley 42 miles northeast of Anchorage, was selected as the site for the primary observatory due to its proximity to bedrock for instrumentation and to communications facilities.
Construction of the observatory installations, the task of engineering and assembling the data systems, and the hookup of the extensive telecommunications and data telemetry network was completed in the summer of Originally, the tsunami warning responsibility for Alaska was shared by the three observatories located at Palmer, Adak and Sitka.
Sitka, a seismological observatory sinceand Fairbanks were the only two seismic stations operating in Alaska in The responsibilities of Adak and Sitka were limited to issuing a tsunami warning for events occurring within miles of their location.
In later years, the responsibility to provide tsunami warning services for Alaska was transferred from the Adak and Sitka observatories to the Palmer Observatory. Sitka and Adak Observatories were eventually closed in the early s, although the seismic instrumentation is still maintained.

Geological Survey detected the earthquake shortly before 10 p. The advisory was later canceled, but PTWC urged continued caution and warned there still may be minor sea fluctuations over the next few hours. The earthquake struck in the ocean between Honduras and Cuba. USGS initially reported a 7. Jamaica and parts of Central America had also faced possible tsunami conditions.
Some homes in Honduras were cracked due to the quake, but there were no immediate reports of serious damage or casualties related to the event, according to the Associated Press.Comunicazione n

Tuesday's quake -- the strongest and likely the most damaging of a series of quakes that have hit the island since December 28 -- left a man dead, caused dozens of homes and structures to crumble and cut power and water service to swaths of the island.

In Ponce, roughly a mile drive east of Indios, a year-old man was killed and at least eight others were injured Tuesday, the city's emergency management director, Angel Vasquez, said. More thanof Puerto Rico's 3.Extensive diversity and complexity of tectonic regimes characterizes the perimeter of the Caribbean plate, involving no fewer than four major plates North America, South America, Nazca, and Cocos. Inclined zones of deep earthquakes Wadati-Benioff zonesocean trenches, and arcs of volcanoes clearly indicate subduction of oceanic lithosphere along the Central American and Atlantic Ocean margins of the Caribbean plate, while crustal seismicity in Guatemala, northern Venezuela, and the Cayman Ridge and Cayman Trench indicate transform fault and pull-apart basin tectonics.
Motion is accommodated along several major transform faults that extend eastward from Isla de Roatan to Haiti, including the Swan Island Fault and the Oriente Fault. These faults represent the southern and northern boundaries of the Cayman Trench. Further east, from the Dominican Republic to the Island of Barbuda, relative motion between the North America plate and the Caribbean plate becomes increasingly complex and is partially accommodated by nearly arc-parallel subduction of the North America plate beneath the Caribbean plate.
This results in the formation of the deep Puerto Rico Trench and a zone of intermediate focus earthquakes km depth within the subducted slab. Although the Puerto Rico subduction zone is thought to be capable of generating a megathrust earthquake, there have been no such events in the past century.

The last probable interplate thrust fault event here occurred on May 2, and was widely felt throughout the island with documented destruction across the entire northern coast, including Arecibo and San Juan. Sincethe two largest earthquakes to occur in this region were the August 4, M8.
A significant portion of the motion between the North America plate and the Caribbean plate in this region is accommodated by a series of left-lateral strike-slip faults that bisect the island of Hispaniola, notably the Septentrional Fault in the north and the Enriquillo-Plantain Garden Fault in the south.
Activity adjacent to the Enriquillo-Plantain Garden Fault system is best documented by the devastating January 12, M7. Moving east and south, the plate boundary curves around Puerto Rico and the northern Lesser Antilles where the plate motion vector of the Caribbean plate relative to the North and South America plates is less oblique, resulting in active island-arc tectonics. As a result of this subduction, there exists both intermediate focus earthquakes within the subducted plates and a chain of active volcanoes along the island arc.
Although the Lesser Antilles is considered one of the most seismically active regions in the Caribbean, few of these events have been greater than M7. The island of Guadeloupe was the site of one of the largest megathrust earthquakes to occur in this region on February 8,with a suggested magnitude greater than 8.
The largest recent intermediate-depth earthquake to occur along the Lesser Antilles arc was the November 29, M7. Sincethe largest earthquakes to occur in this region were the October 29, M7. Further to the west, a broad zone of compressive deformation trends southwestward across western Venezuela and central Colombia.
The January 31, M8. Along the western coast of Central America, the Cocos plate subducts towards the east beneath the Caribbean plate at the Middle America Trench. This subduction results in relatively high rates of seismicity and a chain of numerous active volcanoes; intermediate-focus earthquakes occur within the subducted Cocos plate to depths of nearly km. Sincethere have been many moderately sized intermediate-depth earthquakes in this region, including the September 7, M7.A strong 6.
The quake's first reported victim, a year-old resident of the southern city of Ponce, died after a wall fell in his home, El Nuevo Dia newspaper reported.

The island's electric power grid was reported to have collapsed, and houses and other structures, particularly in Guayanilla, home to around 20, people, and nearby Guanica were heavily damaged. The mayor of Guayanilla told local news channel NotiUno that the town's church had collapsed in the incident and pictures on local media showed the structure crumbled into pieces. The quake is the most powerful in a series of tremors that have shaken the island since December 28, including a 5.

Tuesday's quake was the strongest of the series of tremors that have shaken the island since December Puerto Rico is no stranger to recent natural disaster. The island was devastated in by Hurricane Maria, a Category 4 storm that shattered the island's already shaky power grid, overwhelmed public services, left many residents without a roof over their heads, and claimed several thousand lives, according to government estimates.
