With your expedition what food do you have to eat
and where do you sleep?
On this expedition we're lucky we can get up and down
the volcano in a single day. Therefore, we stayed in local hotels
and ate the local food (lots of nice tropical fruit). Sometimes,
we have to sleep on the volcanoes (I've done this in Indonesia)
and then I carry foods which are light - breads, biscuits, instant
What insight do you expect to gain in the field
the expedition? What hypothesizes are you collecting data to test?
We're looking at the effects of changes in the subduction
parameter on the gas chemistry, as well as the mass balance of various
volatile species along the strike of the Central American margins.See
the tabs on the home-page.
I just want to say how brave you all are completing
research on volcanoes so to better our understanding on how they
operate and when they will next erupt. It is facinating watching
you trecking across such beautiful terrain. In Australia we are
lucky to not have any active volcanoes as far as I am aware. Keep
up your interesting web page. Good luck. (Lyn Best, Australia)
Thanks for your support.
Today (6/1) you described your walk through the
Irazu volcano, and mentioned what measures the local population
has considered to fight the volcano in the past (atomic bomb, filling
with water, drill a tunnel). Are there any means, if an eruption
is expected, to fight it, or to guide the lava and other material?
Would drilling a tunnel help to 'take the pressure away'? (Steef
de Bruijn, The Netherlands)
The only measures of which I am aware involved building
dams on Mount Etna, Sicily in an effort to block or divert lava
flows. Mostly, it's a case of seeing the results of a volcanic eruption
rather than trying to influence them.
In your life what was the largest
erruption you studied? (Steven)
Kratatoa in Indonesia
Hi, my name is Krystal. Have you ever been close
to a volcano when it is erupting? (Krystal M. Williams, age 11)
Well, we try to sample volcanoes when they are not
erupting - its safer that way! However, I have been on the big island
of Hawaii and have seen lave there although it was a fairly passive
eruption with lava mainly contained within a lava lake.
How do you travel all around the volcano every
day? (Daniela Avalos, West View Elementary School, San Diego,
We drive as much as possible then walk up the remainder.
Interestingly, lots of travelling involves going downhill - once
we reach the top then we might have to go down to go into the crater
- as we did with Turrialba and Poas volcanoes during the first days
of the expedition.
When do you explore in Costa Rica again? (Jeremy,
We might try and go to Costa Rica in July of this
year. However, the next locality on our itinerary is Guatemala.
Is getting near volcanoes really tough? (Kyle
Rudolph, St. Joseph, Arkansas)
Sometimes! Some volcanoes have roads to the top so
that's easy. For others, it might involve a long hike.
How do you find active volcanoes? (Mitch Mitchell,
St. Joseph, Arkansas)
There are a number of excellent books out cataloguing
active volcanoes of the world. Check out our Links
page and go to the Global Volcanim Project to find out more about
the world's active volcanoes.
Hello my name is Mariel, and I would like to ask
the scientist a question; What is so interesting about doing this
video on volcanos? Please write back to me! Thank You! (Mariel
Silva, West View Elementary, San Diego, California)
So we might inspire kids like you to become interested
Where is the closest volcano to San Diego, California?
How long have you been studying volcanoes? What do you think was
the best eruption of all time? (Michelle Valdez, West View,
San Diego, California)
You don't have to travel far to get to see volcanic
activity. Mammoth Mountain on the eastern side of the Sierra Nevada
has lots of geothermal activity (associated with long valley caldera).
About 5 - hours drive south in Baja, Mexico, are volcanic craters
(San Quintin). I've been studying volcanoes since 1983 when I visited
Iceland and climbed my first volcano - Hekla, the highest volcano
in that beautiful country.
There are lots of interesting eruptions through time. I'm interested
in Krakatoa in Indonesia. This volcano erupted in 1883, causing
widespread damage. It was well documented and it interesting scientifically.
I visited the volcano in 1992.
Why were they sampling volcanoes if they were oceanographers?
(Bryn Mawr, Maryland)
Volcanoes occur under water as well as on land. We
study volcanoes where-ever they occur. Often we can learn about
undersea volcanoes by looking at their on-land equivalents.
Has anyone ever survived volcano burns and has
any of your team members suffered injuries? (Booker T., Racine,
Yes - the most famous example being a prisioner in the gaol at St.
Pierre on Martinque in the Caribbean. The eruption of 1902 from
the nearby volcano of Mt. Pelee killed the whole population of the
town except for the prisioner who was badly burned - but survived!
I (David Hilton) had a little bit of lava (spatter) land on me at
Kilauea volcano in Hawaii. It burned - and hurt!
How many volcanoes, active or
inactive, are there in Costa Rica? (Briana Wood, Las Vegas,
Guillermo answers - 300 volcanic centers in total. These include
active, dormant and extinct. From the last 11,000 years, there are
about 11 volcanoes (at least) which have been active. From the first
arrival of the Spaniards (500 years) there have been 5 active volcanoes
- Rincon de la Vieja, Arenal, Poas, Irazu and Turrialba (all on
When did the last volcano erupt in Costa
Rica because I am studying it for a report.
Check out the Global Volcanism Program (the link is on our web-site)
or go directly to the Central America section and scroll down to
Costa Rica to search for the information you're after. http://www.volcano.si.edu/gvp/
I'm from West View Elementary school, and I'm was
wondering if Costa Rica is built on islands or volcanoes? Thank
you Ashley. (Ashley Camargo, West View Elementary, California)
Costa Rica has many volcanoes as well as sediments
which were laid down in the oceans but were later uplifted by movements
of the plates.
