The Toba Super-Eruption: The Global Catastrophe that Creationists Ignore

Comparison of material emitted for a number of famous volcanic eruptions. All the ones that emitted 100 cubic kilometers or more and considered super-eruptions.    Toba has erupted more than once but the one shown is the youngest.   Image credit: USGS - http://volcanoes.usgs.gov/images/pglossary/eruptionsize.php

Sudden catastrophic events are not unknown in Earth’s history.  Large craters are evidence of past cosmic impacts.  Widespread layers of volcanic ash are a testimony of massive volcanic eruptions.   But when did these catastrophes occur and could they have impacted human history? Standard geological models place the largest catastrophic events many eons ago.  So long […]

Smoking Gun Evidence of an Ancient Earth: GPS Data Confirms Radiometric Dating

640px-Plates_wikipedia

My last post, on the tectonic origins of the Dead Sea and Jordan Valley, brought me face-to-face once again with one of the most striking pieces of evidence for an ancient earth that I am aware of. Take a look at this graph. This graph shows the smoking gun. Smoking gun evidence of what? That […]

Rewinding the Clock: An Asteroid Family History

Artist conception of the breakup of an asteroid into separate family members.

You might think of the asteroid belt between Jupiter and Mars as a assortment of space junk floating randomly in space. There are millions of asteroids of which more than 100,000 have been measured and mapped by astronomers. But analysis of those asteroids has shown that there are groups of asteroids that are related to one another and are referred to family members

My Interview with a Martian: A Story of Origins

Everything has an origin.*  Some stories of origins are very simple (eg. the current island of Krakatoa from a volcanic blast recorded in history)  while others are much more complex (eg. the Grand Canyon).  The study of origins is the study and reconstruction of past events.  We have eyewitness accounts of some events from the […]

NH Notes: Answers in Genesis and a Mountain of Extraterrestrial Dust

mars-whole-planet

How long would it take for falling dust to accumulate into a mound 2 1/2 miles tall?  Answers in Genesis has commented (Wind, not water, may have built the Martian Mount Sharp) over the weekend on the same research article that I referenced in my post last week (NH Notes: Did Wind and Dust Create a […]

Non-Martian Rocks on Mars: Finding Small Meteorites on another Planet

Meteorite on Mars: Shelter Island Iron

Previously we explored some meteorites that have been found on Earth that are very likely from Mars (Finding Mars on Earth).   Only a small percentage of the meteorites found on Earth are from Mars with a few more (over 100) originating from the moon.   The remainder presumably come from the far reaches of the […]

Finding Mars on Earth: A Conversation about Martian Meteorites

Tissint-mars-meteorite-morocco

Maybe you missed it last week with all the excitement of  the pictures from Curiosity and its analysis of the rocks on Mars (See my last post: Curious Geology: Stunning Images Reveal a Complex Mars) but there was another pronouncement of further evidence that watery processes were once active on Mars.  Where did this evidence […]

The Mars Curiosity Rover: A Geological History Detective

nasa_curiosity_rover-geology-mars

How could anyone not be curious about Mars Curiosity rover?   NASA gambled by playing up the “7 minutes of terror” landing, using social media very adeptly to get a huge audience right in the middle of the Olympics.  Failure of the rover to safely land surely would have been a crushing blow to the […]

As The Asteroid Tumbles: Asteroids and the Age of the Solar System

Eros asteroid.  Despite its oblong shape it has been shown to be rotating around is principle axis point.

There are millions of asteroids orbiting the solar system most of which are found in the asteroid belt between Mars and Jupiter. Studies of these asteroids, as part of an effort to assess the threats to earth, have allowed us to track and paths, sizes and rotational frequencies of over 1000 asteroids.

The Toba Super Eruption: A Non-Flood Catastrophe – The Artifacts Say Yes!

The Toba volcano is found near the center of Sumatra, Indonesia. It has been estimated that at least 2800 cubic kilometers of material was thrown into the air during the explosion or series of explosions. To put that in perspective the Krakatoa volcano threw just over 2 cubic kilometers of material into the air some of which circled the globe causing dazzling sunsets in Europe.

Meteorite Impact Craters and Apparent Age – An Addendum

Victoria Crater

As a way of simplifying yesterday’s rambling entry I offer the following comparison of two meteorite impact craters. The first, Victoria Crater, is from Mars and the second, Amguid Crater, is in Algeria, Africa.  Let’s compare the features and then ask if they can help us to evaluate the current young earth geology models and […]

Kamil Meteorite Crater: A “Young” Impact on Earth Compared to Craters on Mars

Kamil Crater

Kamil Meteorite crater is a recently discovered crater in Egypt which is an example of a very young crater on earth. What can Kamil Crater tell us about the origin of craters not only on Earth but also on other Planets? And what does this tell us about the age of the Earth and those other planets?

Mercury follow-up: A watery beginning?

Artistic depiction of the formation of planets around a new star (NASA/JPL/Spitzer)

How were the planets formed?   While young earth creationists appear to be fairly unified in their convictions about the origin of the geological features of the earth, the question of how the planets and the moon came to appear as they do seems to be one for which there is little consensus  among YECs other […]

Walter Brown and the Origin of Asteroids and Impact Craters on other Planets

Meteor Crater in Arizona

Sometimes you run across an article so ridiculous you can hardly believe you just read it.  Such is the case with a chapter of Walter Brown’s book “In the Beginning.”    The whole book has significant problems but while I was delving a bit deeper into the origins of meteorites and asteroids and the appearance of […]

A Young Mercury? Apparent Age Redux

The Planet Mercury

Another blog brought to my attention a recent daily news update from ICR that comments on the origins of Mercury.  The latter article comments on recently published results of the MESSENGER spacecraft that is now orbiting the planet Mercury (Science abstract).  That spacecraft is mapping the surface of Mercury with several instruments including  X-ray fluorescence […]
