The Tamu Massif, the largest volcano on Earth, erupted catastrophically

In September 2013, a team of scientists led by William Sager of Texas A&M University reported finding the largest single volcano on earth.1 It is under the ocean and is now inactive.

Dubbed ‘The Tamu Massif’, it is located about 1,600 km (1,000 miles) east of Japan, and is the largest feature of an underwater mountain range called Shatsky Rise.

Reports noted the unusual shape of the huge lava deposit.2 It’s low and broad, a shield volcano. Most other volcanoes that erupt under the ocean are small with steep sides. The seafloor is dotted with thousands of such steep-sided underwater volcanoes, or seamounts.

The broad, flat shape means that the molten lava erupted at such an enormous rate that it travelled rapidly across the ocean floor for a long distance while still molten. When it was eventually cooled by the seawater, it began to solidify and become gummy.

This eruption was one of many similar eruptions all over the planet around the time when geologists say that the continents were breaking up. The volume of lava erupted was enormous, and the deposits are called Large Igneous Provinces or LIPs for short.3

The researchers recognize that the eruption was catastrophic. Sager said:

“The bottom line is that we think that Tamu Massif was built in a short (geologically speaking) time of one to several million years and it has been extinct since.”2

But, for it to have taken several million years to form would mean the lava would have flowed out slowly, and it would not have formed a shield volcano. There was another feature about the volcano that puzzled the researchers. Sager again:

“One interesting angle is that there were lots of oceanic plateaus (that) erupted during the Cretaceous Period (145–65 million years ago) but we don’t see them since. Scientists would like to know why.”2

Even while reporting the eruption as catastrophic, they still ‘date’ it using the assumption that everything in the past happened slowly and gradually.

But a catastrophic eruption happens quickly. When we relate this to the catastrophe of Noah’s Flood, we can reinterpret the timing and we discover that the volcano would have erupted about halfway through the year-long Flood,4 which occurred about 4,500 years ago. And it would have taken just days and weeks, not several million years, otherwise it would have solidified before it could have spread so far. Creation geologists conclude that most rocks now exposed on earth were deposited during the Flood. It was enormous and catastrophic, meaning everything happened quickly.

So, there is a simple reason why these eruptions took place in only one period of earth history, and we don’t see them since. The volcanos erupted mid-way through the Flood when the ocean basins began to lower and the floodwaters began to recede from covering the continents. The Flood happened once in earth history and it won’t happen again. Genesis 9:11 records God saying:

“I establish my covenant with you, that never again shall all flesh be cut off by the waters of the flood, and never again shall there be a flood to destroy the earth.”
