Killer Tsunami

Killer tsunami

Dr Gary Kinsland of the University of Louisiana at Lafayette was involved in two seemingly unrelated projects when an unexpected connection was revealed. He was studying the Chixculub crater that marked the end of the Cretaceous Killer tsunami. Meanwhile, he was also assigning graduate students to map the presence of coalbed methane in northern Louisiana using ground-penetrating radar that reflects off changes in subsurface composition.

Years later, after further investigation, those ripples are the subject of a paper in Earth and Planetary Science Letters. They look like those left behind by ordinary waves on sandy beaches — but are 16 meters 53 feet high and 0.

Initial error

Seismic survey image of the horizon in northern Louisiana at the end of the Cretaceous era. The ripples look small but are three stories high. Finding those impressions so many years later is killer tsunami surprising, but these researchers think the ripples were preserved because they were made not on land, but in what was then just the right depth of water.

The contours on what was once the sea bed have been buried in almost a mile of sediment and soil since then. Calculating the depth of water at the time — around 60 meters feet — and the ripple here, the authors calculate the waves responsible could have been up to a mile victorian crime and punishment, matching previous estimates. Not everyone is convinced. Sciencenews quotes Dr Pedro J.]

Killer tsunami - were visited

Richard M. Mitterer, a long-time geosciences professor at The University of Texas at Dallas UTD , will deliver a lecture Tuesday, March 29, on the Sumatra-Andaman Island earthquake three months ago and the deadly tsunami that resulted from it. Richard Mitterer Mitterer, who was one of the original members of the faculty when UTD was created in and who has taught an undergraduate course in oceanography since , will discuss the geological forces that caused the earthquake and tsunami and the incredible level of destruction that occurred.

Killer tsunami - seems

Authorities also widened a no-go zone around rumbling Anak Krakatoa to five kilometres three miles — up from a previous two kilometres — and warned shell-shocked residents to stay away from the coast, after more than were killed by Saturday night's killer wave. Plumes of ash burst into the sky as pyroclastic flows -- hot gas and other volcanic material — flowed down the crater, threatening anyone too close to the volcano and raising the risk of rough seas for boats in the vicinity. But the status change sparked new fears with many residents already scared and refusing to return to their communities over fears of another tsunami. At least people were killed, with 1, people injured and another were missing. Nearly 22, people have been evacuated and are living in shelters. On Wednesday evening, the disaster agency said that wind was blowing "ash and sand" from the volcano to the nearby towns of Cilegon and Serang on Java, and advised residents to wear masks and glasses if they had to venture outdoors. Torrential rains have sparked flooding in some areas, hampering the relief effort and heaping more misery on the stricken region, as thousands cram emergency shelters. Medical workers have warned that clean water and medicine supplies were running low -- stoking fears of a public health crisis. Indonesia, a vast Southeast Asian archipelago, is one of the most disaster-hit nations on Earth due to its position straddling the so-called Pacific Ring of Fire, where tectonic plates collide. The tsunami was Indonesia's third major natural disaster in six months, following a series of powerful earthquakes on the island of Lombok in July and August and a quake-tsunami in September that killed around 2, people in Palu on Sulawesi island, with thousands more missing and presumed dead. killer tsunami.
