Can a Tsunami Strike the Atlantic Coast?
Can a tsunami strike the beach of New Jersey, North Carolina,[link widoczny dla zalogowanych], or Florida? The question crossed my mind as I was doing research for my action/adventure novel TSUNAMI, even though the paperback is set in the Pacific.
The question is yeah, a tsunami kicking the Atlantic Coast is feasible, but defect in ... probable than one striking Alaska,[link widoczny dla zalogowanych], Hawaii, or the Pacific Northwest. When it comes to the varieties of natural memorabilia that start tsunamis -- undersea earthquakes, submarine landslides, and volcano eruptions -- the Atlantic is a many tamer ocean than the Pacific. The Pacific basin is encircled along the flagrant Ring of Fire with its hundreds of active volcanoes and dozens of perilous,[link widoczny dla zalogowanych], earthquake-prone subduction zones. The Atlantic has distant fewer geological areas capable of posing a genuine tsunami threat. But there are some, and they ought be taken seriously.
The one most talked about is the Cumbre Vieja volcano in the Canary Islands, 3000 miles from Boston and 3700 miles from Miami. In 1949,[link widoczny dla zalogowanych], a flank of the volcano split off, creating a 3-ft. breach, the flank sliding down 3 feet toward the ocean before it stabilized. Earthquakes and a buildup of oppression inside the volcano were associated with the event. The concern is that variant earthquake or eruption could dislodge the all flank and send as many as 300 cubic miles of debris plunging into the ocean. One school of thought suggests that such a monster landslide would start a tsunami capable of approaching the east seaside of the United States 5 or 6 hours later.
Even whether such an accident were to happen, many geologists dispute the notion that it would mail a killer tsunami smashing into the East Coast of the U.S. The altitude of the initial wave would be colossal, but the length among waves would be relatively short, averaging its competence to retain its stamina while travelling long distances would be lessened. Undersea earthquake-generated tsunamis typically have long wavelengths, or distance between waves in the practice, and can voyage long distances without premonitory detriment of energy. In compare, landslide-initiated tsunamis tend to have short wavelengths and are commonly confined to regional areas where they tin be extremely disastrous. In 1883, the Krakatau eruption dumped millions of tons of debris into the ocean and started a 135-ft. tsunami that did amazing damage to Sumatra and neighboring islands but did not influence other areas.
To sum it up, there are 2 points of view. One maintains the collapse of a chunk of Cumbre Vieja into the ocean could jeopardize the Atlantic Coast of the U.S. with a major tsunami, meantime the other outlook holds that the dynamics of wag formation make such a result unlikely.
The only true subduction district close to the East Coast is the Puerto Rico Trench, which escapes scampers because 1000 miles from Puerto Rico eastern past the Lesser Antilles and out into the Atlantic Ocean. The deepest point in the Atlantic at 28,200 feet lies in The Puerto Rico Trench. Along this trench, the Caribbean tectonic plate is subducting, or sliding below, the North American Plate. This is not as large or active a subduction zone for maximum of those in the Pacific, merely undersea earthquakes have occurred there,[link widoczny dla zalogowanych], resulting in tsunamis that affected the islands in the Caribbean. The final tsunami in the space happened in 1918 when 32 people died in Puerto Rico and the Virgin Islands.
Mt. Pelee on Martinique is one of several active volcanoes in the Lesser Antilles arc. The 1902 eruption of Mt. Pelee is one of the largest on log. It is possible that volcanic debris from hereafter eruptions could crash into the ocean and start a localized tsunami.
Submarine landslides by the edge of the continental shelf according the Atlantic Seaboard might too start tsunamis namely could shock coastal cities. In 1929,[link widoczny dla zalogowanych], a 7.2 magnitude earthquake off Newfoundland started an undersea landslide down the continental shelf. The resulting tsunami swept ashore and annihilated 8 people.
The Atlantic Tsunami Warning System was installed in 2006,[link widoczny dla zalogowanych], comprising five Deep Ocean Assessment and Reporting of Tsunami (acronym DART) buoy stations. Single stations are located off Charleston, Miami, and New Orleans. Two are positioned off Puerto Rico close the Puerto Rico Trench. All invest real period observation of undersea disturbances able of starting tsunamis that could impact the Atlantic, Caribbean, and Gulf Coasts. Plans call for the addition of at fewest two extra DART stations.
If you live in a low-lying area on the Atlantic Coast, be aware that a tsunami is forever a likelihood, and be arranged to evacuate on a moment's notification as directed by local authorities.
