Just happened…

The earthquake is a 7.8, and it’s that big red dot in the Pacific, near New Zealand.

There are tsunami fears. Warnings are in effect for Tonga and the Kermadec Islands, according to the Pacific Tsunami Warning Center.

The New Zealand dollar is falling a bit on the news. You can see the big dropoff on the Kiwi on this chart.

“What Puerto Rico Trench?”  Exactly.

The arrows in the map above show the direction the underlying Caribbean tectonic plates are moving, with the resultant build-up of pressure releasing into a myrid of earthquakes in the region over the years. Puerto Rico is the smaller green island in the middle, with the Dominican Republic the larger island to the left. The string of other Caribbean islands is buried under the earthquake markers that Read more…

Indonesia was hit by a large earthquake and a series of strong tremors Sunday afternoon. A 6.5 magnitude quake, the latest in string of strong quakes to hit the Pacific Ring if Fire region during the last week, struck the country’s easternmost Province of Papua 1.16 p.m. GMT.

The quake was centred 53 kilometres (33 miles) northeast of Waren, a town on the northern coast of Papua island, according to Indonesia’s Meteorology and Geophysics Agency.  It was also felt in nearby Biak island, and Enarotali town on the main island The U.S. Geological Survey put the initial quake’s magnitude at 6.4.

The region was hit by at least moderate tremors in the following hours. The tremors measured 5.4 (x2), 5, 4.5 and 4.3 on the Richter Scale. There were no immediate reports of damage and no tsunami warning was issued.

Papua comprises most of the Read more…

Oregon Coast’s Vulnerability

tsunami map Recent research suggests that a Cascadia Subduction Zone earthquake could create tsunami waves that impact over 1,000-km of coastline in the U.S. and Canada. Source: USGS

The northwestern coast of Oregon is susceptible to both local and far-field tsunamis. The Cascadia Subduction Zone, where the eastward moving Juan de Fuca plate meets the westward moving North American Plate, is just off the Pacific Northwest coast of the United States and Canada. It is a 750-kilometer long fault zone. This area is very active tectonically, and therefore has the potential to produce large earthquakes and possibly, subsequent tsunamis. This subduction zone is thought to have last ruptured in 1700.

Additionally, far-field earthquakes throughout the Pacific are also capable of spawning tsunamis that could eventually reach the Oregon coast. Historical records show that since 1812, about 28 tsunamis with wave heights greater than one meter have reached the U.S. west coast. The March 1964 “Good Friday” earthquake created the most devastating of these tsunamis. The epicenter of this earthquake was near Anchorage, Alaska. The tsunami that followed this earthquake reached coasts all along the western U.S. within six hours. Cannon Beach, a small coastal community in northwestern Oregon was inundated during Read more…

June 21, 2011ANTARCTICA – A 5.5 magnitude earthquake struck the South Sandwich Islands region, situated around 750km south east of South Georgia, in the South Atlantic early Sunday.  It was the latest in a series of quakes to hit the Antarctic Region during the past 24 hours. The moderate quake struck at 9.37am GMT at a depth of 137km and was centered 69 km (42 miles) NNW of Visokoi Island and 330 km (205 miles) NNW of Bristol Island. The last significant earthquake to be recorded in the South Sandwich Islands region occurred on Read more…

Seismic chart showing 2011 Japan quake

2011 is on target to record the largest number of earthquakes in a single year for at least 12 years.

Research by Irish Weather Online, using data from the US Geological Survey (USGS), has found that earthquake activity (5.0-9.9 magnitude) from 01 January to 19 June 2011 is already exceeding the total annual seismic activity for the years 2001, 2002 and 2003.  2011’s total number of recorded earthquakes is also expected to exceed the most seismically active year of the past 12 years, 2007.

A total of 1,445 earthquakes, ranging in magnitude from 5.0 to 9.9, have been recorded in the year up to 19 June. The total number of earthquakes recorded globally for the entire of 2007 was 2,270.

The massive earthquakes in Japan (2011), Chile (2010), Sichuan (2008), Sumatra (2005 and 2008) and Indonesia (2004) have served to remind us of the devastating impact of earthquakes on life and property.  While the number of earthquakes ranging Read more…

Something Strange With Volcano Eruption in Chile

What appears to be an enormous ash cloud rising from the eruption of a long dormant volcano named Puyehue in southern Chile on June 4, 2011, isn’t quite matching up with the location of the recorded earthquakes today in the immediate area.

“The Cordon Caulle (volcanic range) has entered an eruptive process, with an explosion resulting in a 10-kilometer-high gas column,” Chilean state emergency office said.

The thing is, for some unknown reason, as of this writing, eight earthquakes near magnitude 5 have shook the earth near the Puyehue volcano. The problem is, the earthquakes are located 20 to 40 miles away from the eruption! Very Strange Indeed. (Strange because one would think that Read more…

Doomsday fire: Millions of volcanoes are stirring beneath the world’s oceans

In 1993, marine geophysicists aboard the research vessel Melville discovered 1,133 previously unmapped underwater volcanoes off the coast of Easter Island. Though some of the newly discovered volcanoes rose as much as one-and-a-half miles above the seafloor, their summits still remained half a mile below the water’s surface- all this in a comparatively small area of only 55,000 square miles, about the size of New York State. The geophysicists had increased the known supply of underwater volcanoes by more than ten percent just in a matter of months. That was 1993. Today, scientists estimate that there are more than three million underwater volcanoes. That’s a three followed by six zeroes! In 2007, oceanographers Hillier and Watts surveyed 201,055 submarine volcanoes. “From this they concluded an astounding total of 3,477,403 submarine volcanoes must reasonably exist worldwide,” said this article by John O’Sullivan. Hillier and Watts “based this finding on the earlier and well-respected observations of Earth and Planetary Sciences specialist, Batiza (1982) who found that at least 4 per cent of seamounts are active volcanoes.” According to Batiza’s survey, the Pacific mid-plate alone contains an incredible 22,000 to 55,000 underwater volcanoes, with at least 2,000 of them considered active.
