Whoever thought lightning would strike in the same place 14 years after the infamous Christmas Tsunami of 2004. There are many entries regarding the 2004 tsunami on the blog. It was the first major event documented here. Now, there is another and what are the odds of such an event only a few days apart after 14 years.

Saturday’s tsunami in Indonesia (click here) was caused by a chunk of the volcanic Anak Krakatau island slipping into the ocean, it was confirmed on Monday, as officials at the country’s natural disaster agency said it must develop a new tsunami early warning system.
At least 373 people were killed, hundreds injured and many buildings were heavily damaged when the tsunami struck, almost without warning,
along the rim of the Sunda Strait, between Java and Sumatra islands....
Due to a lapse in appropriations, (click here) the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted. For more information, please see www.doi.gov/shutdown
...Anak Krakatau had been spewing ash and lava for months before a 64-hectare section of its south-west side collapsed, an Indonesian official said. “This caused an underwater landslide and eventually caused the tsunami,” Dwikorita Karnawati, the head of the meteorological agency, said....
I have to bring to the dialogue the fact the Hawaiian Hot Spot is still unstable. This was a volcanic collapse. That has been occurring with the Hawaiian Hot Spot. The Pacific Plate is moving. There have been significant earthquakes around the "Ring of Fire." The earthquake in Alaska displaced enormous amounts of rock. This is a very dangerous Pacific coastline and no one should be assessing symptomatic volcanoes in the same manner as history dictates. This is a highly volatile Pacific coastline, including island countries in the Pacific Ocean.
Additionally, the leaders of countries need to be complaining to Trump about the impact of the political government shutdown regarding support services from NOAA and NASA. An assessment has to be completed in every Pacific Coast country of their tsunami alarms. A tsunami is a tsunami and why this tsunami occurred without detection is worrisome. There may be a level of denial that if an alarm went off without a detectable ocean earthquake it was irrelevant. There was an earthquake. There are earthquakes with volcanic eruptions, especially if the land is acting as a caldera as in this eruption.
No volcano should be taken for granted. This is an entirely different paradigm in that the Hawaiian Hot Spot is in motion in a way that removes volcanoes from their pressure conduit to the magma chamber/reservoir.
Basically, the volcanoes act more like calderas than volcanoes because there is no pressure from under the vests or crater. The conduits are collapsing.
On this timeline, further down the road the magma will seek eruption from under land that is currently stable. We already know there is a growing underwater volcano south of the Hawaiian Island Chain. I think the Pacific Coast movement will continue to be a worry for some years yet if not the next decade. Scientists that are volcano specialists will need to be working to monitor the land that is currently volcanoes and the land that is at risk to become a new volcano.
There are new conduits forming from the magma chamber. For every volcano conduit collapse that occurs there is at least one other conduit forming. There is no indication the magma is cooling and causing collapse, the Pacific Plate is moving and that is a fact.
