There are several kinds of volcanoes. Mount St. Helen's is characteristic of a lava dome.
Etna is typical of a composite cone, or stratovolcano.
Flood basalts are the result of a massive eruption, in which basalt lava pours over a vast amount of land or ocean floor. The most recent one is in the Columbia River region of the western United States- some sixteen million years ago.
Shield volcanoes are characteristic of Hawaii.
Cinder cones are very common types of volcanoes characterized by a single vent.
Volcanoes wreck havoc- some examples are here.
The same applies to earthquakes, which are capable of killing more people.
Display panels look at what makes earthquakes happen- both major and minor fault lines.
Earthquakes are scary and life threatening.
ReplyDeleteWe had one here some years ago. On the scale of things it was minor.
DeleteIntriguing subject.
ReplyDeleteIndeed.
DeleteSome scary subject...
ReplyDeleteTrue.
DeleteReminds me of teaching the grade 11 geography course.

DeleteEarthquakes are scary, I have felt two right here in Maryland. Take care, have a happy weekend.
ReplyDeleteThey leave an impression.
Delete...I went to Mount Saint Helens a number of year after its eruption, it was quite a sight to see.
ReplyDeleteI'd like to see it.
DeleteEarthquakes used to freak me out when I used to travel in Japan.
ReplyDeleteUnderstandable.
DeleteVolcanoes are both mesmerising and lethal. I learnt a lot from this post, thank you.
ReplyDeleteYou're welcome.
DeleteOhhh...
ReplyDeleteI'm so glad I live in an area far from volcanoes and possible earthquakes.
A warm greeting to you and
I wish you a happy weekend.
We get the odd quake but the magnitude isn't like what you'd get near a major fault line.
DeleteWe were awakened by what we thought was an earthquake in Newfoundland one night. Turns out, it was a rock burst from the abandoned mine which was being flooded under the town. Scary enough though. The real thing must be terrorizing!
ReplyDeleteWhat an experience.
DeleteI hope you survived yesterday's storm!
ReplyDeleteI was inside when it hit.
DeleteNature can be scary.
ReplyDeleteIt can.
DeleteVery well documented.

ReplyDeleteIndeed.
DeleteWe had earthquakes in Oregon in the early 90s and one in Alaska around 2000 both were scary.
ReplyDeleteI can imagine.

ReplyDeleteI agree.

Thanks.
DeleteGreat exhibition photos of this scary event. I remember it like it was yesterday. We were living in California over a thousand miles south, and I couldn't understand why the sky was so yellow with flecks floating down from the sky.
ReplyDeleteAt first I thought it was a fire nearby but when I turned on the local news, they were talking about the volcano and the ash falling. It was surreal and sadly quite horrific.
That volcano left a big mark
DeleteEs un gran espectáculo. lo malo son los daños que ocasionan.
ReplyDeleteUn abrazo
Thank you.
DeleteI've not experienced Volcanos or Earthquakes, but it must be quite scary ...
ReplyDeleteAll the best Jan
