I didn´t see that the question was missing. <br /><br />This part of challenge is very interesting and with lots of unknown topics like Dr. Russell and Rosemary mentions. I thought that was only kind of material and eruption type. And also didn´t know the words that mentions Dr. Russell.<br /><br />So, I did another SearchResearch ]<a href="http://volcano.oregonstate.edu/education/vwlessons/kinds/kinds.html" rel="nofollow">[ kinds of volcanic eruptions </a> The one that sent the mudflows is <i> Plinian </i><br /><br /><br />Also found with [Popocatepetl kind of eruptions <a href="http://volcano.oregonstate.edu/popocatepetl" rel="nofollow">Volcano World Oregon State :Popocatepetl</a> lots of information and links to other sites like Google Scholar and <a href="http://www.geo.mtu.edu/volcanoes/Volcanoes/Index.html" rel="nofollow">Michigan Technological University Volcanoes Page</a> that has very good information about volcanoes.<br /><br />Hope Remmij is ok, since this week didn´t post.<br /><br />Finally, out of topic, one good topic for a future Challenge could be the History of "Taxi". <br /> Ramon Gonzalezhttps://www.blogger.com/profile/16129830563029534511noreply@blogger.comtag:blogger.com,1999:blog-4953008377950396317.post-59256587437574098182013-12-06T19:15:25.896-08:002013-12-06T19:15:25.896-08:00Fred you don’t miss a beat. Finding the right term...Fred you don’t miss a beat. Finding the right term can be a challenge. Here’s Google’s definition [define caldera volcano] is “A caldera is a cauldron-like volcanic feature usually formed by the collapse of land following a volcanic eruption. They are sometimes confused with volcanic craters. The word comes from Spanish caldera, and this from Latin CALDARIA, meaning "cooking pot". …<br /><br />I think you may be referring to the dome which is a ‘lava dome’ according to the <br /><a href="http://newscientist.com/article/dn23835-lava-dome-shows-pressure-rise-at-volcano-popocatepetl.html#.UqKGSlWzKpg" rel="nofollow"> New Scientist article</a><br /><br />I enjoyed looking at this student site <a href="http://library.thinkquest.org/17457/volcanoes/structure.php" rel="nofollow">Thinkquest</a> showing us types of volcanos, structures and a section on calderas and crater lakes. I’m impressed with the details and simplicity. <br /><br />Fred & Ramon I think you have taken search results to a new level. It's great doing these searches with you. I learn from your posts as well. Have a great weekend.Rosemary Mhttps://www.blogger.com/profile/12291661159622665464noreply@blogger.com
