Megatsunami (also known as iminami (斎波?, "purification wave")) is an informal term to describe a tsunami that has initial wave heights that are much larger than normal tsunamis. Unlike usual tsunamis, which originate from tectonic activity and the raising or lowering of the sea floor, known megatsunamis have originated from large scale landslides or impact events.

Here's key excerpts:
The Canary Islands Government has raised the alert level for the El Hierro volcano in the Canary Islands (Spain) to ‘Yellow’, the highest alert status since an unprecedented earthquake swarm commenced in mid-July.
Spanish seismologists, accompanied by the President of the Cabildo de El Hierro and the Minister of Security and Emergency Area, held a press conference on Sunday to reassure the 10,000 residents of the smallest of the Canary Islands that the raising of the alert level does not indicate that an eruption is imminent. They indicated, however, that the number of volcanic earthquakes detected beneath El Hierro continues to increase.
Speaking to the El Pais newspaper during the weekend, volcanologist Juan Carlos Carracedo suggested that an eruption on El Hierro would “not be a major surprise”.
He explained: “It is the youngest of the Canary Islands. There is a ball of magma which is rising to the surface and it is stationed at the limit of the earth’s crust. At the moment we do not know if that ball of magna will break the crust and cause an eruption.”
El Hierro is situated in the most southwestern extreme of the Canaries. The island was formed after three successive eruptions, and consequent accumulations, the island emerged from the ocean as an imposing triangular pyramid crowned by a volcano more than 2,000 metres high.
The volcanic activity, principally at the convergence of the three ridges, resulted in the continual expansion of the island. A mere 50,000 years ago, as a result of seismic tremors which produced massive landslides, a giant piece of the island cracked off, crashed down into the ocean and scattered along the seabed. This landslide of more than 300km3 gave rise to the impressive amphitheatre of the El Golfo valley and at the same time caused a tsunami that most likely rose over 100 metres high and probably reached as far as the American coast.

If there's ever news of a massive landslide in the Canary Islands, likely in association with a volcanic eruption, the entire U.S. East Coast will have about 6-8 hours to evacuate inland before a potential megatsunami hits which means a tidal wave possibly dozens of feet high. This is a little known natural disaster threat that is now becoming all too close for comfort as a volcanic eruption appears imminent on the El Hierro island that triggered a megatsunami ~50,000 years ago.
Although such a U.S. East Coast megatsunami appears to be a low probability, it is somewhat disconcerting that we are seeing this potentially cataclysmic scenario develop into the Autumn season when mass panics occur as well as the time frame of what may be the end point of the Mayan Calendar.
Even so, my primary concern remains World War Three starting with a conflict in the Middle East.
The main point here is God is establishing that the Creator, not creatures (but 'through' creatures), ultimately authors our world's history.
NOTE that the March 11th Japanese earthquake and tsunami occurred a week before a "supermoon" on March 19th.
Some believe that there is a connection.
This might be relevant in that another supermoon occurred with today's new moon:
When at perigee, the moon is about 18,640 miles (30,000 kilometers) closer to Earth than its average distance of roughly 240,000 miles (385,000 kilometers). When perigee occurs during a full moon, the lunar disk can appear about 14 percent bigger in the sky, Samra said.
Tuesday's dark supermoon will be just 222,175 miles (357,557 kilometers) away from Earth.
Some people have speculated that this lunar proximity can have unusual gravitational effects on Earth, triggering dramatic events such as earthquakes.
But the truth is that there's only a very small correlation between full or new moons and seismic stresses, said Jim Todd, planetarium manager at the Oregon Museum of Science and Industry.
"Stronger tidal forces caused by the alignment of the sun and moon may put added stress on tectonic plates," Todd said.
"However, seismologists have found no evidence connecting lunar perigees to heightened seismic activity. Instead the Earth constantly stores up energy and releases it any time the built-up energy becomes too great."
"There will be signs in the sun, moon and stars. On the earth, nations will be in anguish and perplexity at the roaring and tossing of the sea." [Luke 21:25]
