Large Earthquakes Continue To Rock The Pacific, Generating More Tsunamis

More large earthquakes have occurred near the Solomon Islands, generating a 4th tsunami warning.

Over the past 24 hours, large earthquakes have continued to shake the Pacific Rim, sending out more tsunami warnings.

A 4th tsunami warning for the Pacific Islands was issued after a 8.3 magnitude quake struck at Kirakira, Solomon Islands 23 hours ago. Since my last post, April 10, 2014, the following quakes have occurred:

  1. 5.3  Iquique, Chile (offshore)
  2. 8.3  Kirakira, Solomon Islands (tsunami warning issued for Pacific Ocean)
  3. 7.7  Kirakira, Solomon Islands
  4. 5.7  Kirakira, Solomon Islands
  5. 5.6  Kirakira, Solomon Islands
  6. 5.3  Papua New Guinea
  7. 5.9  Kirakira, Solomon Islands
  8. 5.0  Kirakira, Solomon Islands

When an earthquake occurs, I record the initial magnitude reading from the Pacific Disaster Alert Center in Hawaii. You will notice that USGS typically lowers these magnitudes, but I maintain that the initial seismograph reading is the most accurate.

Several large earthquakes have caused tsunami flooding along the Pacific island coasts.

Sea level readings did indicate that a tsunami was generated along the coasts near the earthquake epicenter. If damaging waves subside after two hours of the quake, local authorities can assume that the tsunami threat has passed. A danger to boats and coastal structures remains for several hours after a large quake due to rapid currents.

You won’t hear much about these tsunamis on US mainstream news, but they are very important to the people living in these island regions.

Third Tsunami Watch Issued Within 24 Hours

Central America is continuing to experience some very large earthquakes.

After my last post merely hours ago, another tsunami watch has gone out – the third in 24 hours.

Latest Quakes

  1. 5.0  Visokoi Island (South Atlantic/Antarctica)
  2. 5.6  Papua New Guinea (Solomon Islands)
  3. 6.6 Nandaime, Nicaragua (on-ground)

Tsunami Watch

Luckily, a tsunami was not generated from this quake, primarily because the 6.6 quake occurred on the land, but high waves will be generated within the Pacific.

With the number of large quakes taking place within such a short time span, Hawaii, the Galapagos, and many Pacific Islands should expect high waves, strong rip currents, and some flooding.



More Large Quakes Along Pacific Rim Create Tsunami Watches

High waves will reach the Hawaiian Islands and Pacific Islands after the swarm of big quakes along the Pacific Rim.

So many large quakes are occurring rapidly along the Pacific Rim, it is hard to keep them straight. I have recorded the most recent quakes over the last 19 hours, beginning April 10, 2014. They are currently happening, so I will continue to keep the list updated.

Note: earthquake magnitudes are on the rise. We are seeing less 4.0 + magnitude quakes, which are now being replaced with more 5.0+, 6.0+, and 7.0+ quakes. And remember that USGS loves to keep the magnitudes as low as possible, so a 5.9 quake, to me, is a 6.0; a 6.8 quake is really a 7.0, and on and on.

Beginning April 10, 2014

These quakes created a tsunami watch for The Pacific region and Hawaii.

  1. 5.0  Iquique, Chile (offshore)
  2. 5.2  Pacific-Antarctic Ridge (South Pacific Ocean)
  3. 5.1  Ciudad Sandino, Nicaragua (on-ground)
  4. 6.1  Valle San Francisco, Nicaragua (on-ground)
  5. 6.0  Iquique, Chile (offshore)
  6. 5.6  Tonga (South Pacific Ocean)
  7. 5.1  San Antonio, Chile (offshore)

These quakes created another tsunami watch for The Pacific region and Hawaii, 6 hours later.

  1. 7.3  Papua New Guinea (Solomon Islands)
  2. 5.1  SSW Papua New Guinea (Solomon Islands)
  3. 6.8  Papua New Guinea (Solomon Islands)
  4. 5.2  Papua New Guinea (Solomon Islands)
  5. 5.5  Iquique, Chile (offshore)
  6. 5.5  Papua New Guinea (Solomon Islands)
