View Full Version : Another tsunami has struck.

This time The Solomon islands has been hit. I remember not long ago never hearing about tidal waves but over the last decade they seem to strike with alarming regularity.
Does anyone have any idea why they keep happening? Is it anything to do with Global warming? I learned the other day that the past decade was the hottest on record worldwide.
My thoughts go out to those in the Solomons.

For what it's worth, they are going to become more frequent and much worse as time goes on. The cause can be traced back further than most desire to venture. I'd rather not start a fire by expressing my views on the matter ;)

I don't think underground earthquakes can be pinned on global warming.
I'm pretty sure tidal waves are caused by ocean earthquakes

Hmm a metorite could cause it. Never thought of that one. One could hit in the middle of the ocean and who would know?
I've heard arguments on both sides about global warming. I'm not sure who is right.
I don't know anything about the Solomon Islands, guess a trip to Google is in order.

Here's a copy/paste:
A 7.2-magnitude earthquake triggered landslides and a tsunami that struck the Solomon Islands on Monday, leaving more than 1,000 people homeless but none dead or injured, according to initial reports.
Officials say the tsunami wave triggered by the quake was around ten feet high when it plowed into the coast but that residents had acted quickly with memories of earlier disasters still fresh in their minds.
Three months earlier, a quake-churned tsunami killed more than 200 on nearby Samoa and Tonga. And in April 2007, a tsunami had killed more than 50 people in the thousand-island country.
The Solomon Islands, which lie east of Papua New Guinea, rest on the "Ring of Fire" - an arc of earthquake and volcanic zones that stretches around the Pacific Rim and where about 90 percent of the world's quakes occur.
Monday’s quake was Solomon Islands' first and the largest this week, with at least nine other quakes greater than magnitude 5.0 having rocked the earthquake-prone region, including three Tuesday night.
The island that was hit on Monday, Rendova, is home to only 3,600 – more than 1,000 of which have been affected after some 200 houses were destroyed by the quake.
Emergency food, water and tarpaulins are currently being shipped in.

At least it's not as bad as Aceh in the Boxing Day tsunami a few years back.
Wikipedia tells us that:
Earthquakes, volcanic eruptions and other underwater explosions (detonations of nuclear devices at sea), landslides and other mass movements, bolide impacts, and other disturbances above or below water all have the potential to generate a tsunami.
Ocean levels have been rising for a while, as predicted, and scientists expect the trend to continue. Not sure how much difference it makes but you'd imagine it would tend to make the effect of tsunamis worse. As we clear more land near the sea you'd also expect more landslides.
