Would epicenters in less-deep areas of ocean tend to reduce the impact of a resulting tsunami somehow (wave “breaks” before getting there?)
Safety & HazardsAsked by: Mike Burrell What is the largest tsunami possible? Tsunamis generally reach a maximum vertical height onshore, called a run-up height, of no more than 100 feet above sea level. A notable exception was the 1958 tsunami triggered by a landslide in a narrow bay on Alaska’s coast. Its over 1,700-foot wave was the

Can clouds be formed without a pollen particle’s role?
Safety & HazardsAsked by: Buddy Perez What are 3 conditions needed for cloud formation? Students will discover that three main ingredients are needed for clouds to form: moisture, condensation, and temperature. What role does pollen and dust play in cloud formation? These particles, such as dust and pollen, are called condensation nuclei. Eventually, enough water vapor condenses

Quality control in Seismic Acquisition – How much data is required?
Safety & HazardsAsked by: Patrick Paulson In [1], it is mentioned that just around 10 bytes/minute are sufficient. What is QC in seismic? Summary. Quality Control (QC) is an essential way of seismic data processing follow up necessary to insure appropriateness of the final deliverables. Qualitative approach based mainly on visual analysis of spectra, gathers, sections, slices

Could Australia’s bushfires aerosols actually decrease global temperature?
Safety & HazardsAsked by: Wendy Irvin Writing in the journal Geophysical Research Letters last week, scientists at the National Center for Atmospheric Research reported that those Australian fires poured so much smoke into the Southern Hemisphere’s atmosphere it triggered a “strong and rapid” global cooling effect of about 0.06°C ( 0.01°F). How much carbon did Australian bushfires

Tsunami Characteristics
Safety & HazardsAsked by: Karen Chance As the waves slow down, they can grow in height and currents intensify. Most tsunamis are less than 10 feet high, but in extreme cases, can exceed 100 feet. When a tsunami comes ashore, it will not look like a normal wind wave. It may look like a fast-rising flood or
