Recent Volcanic Activity in Hawaii, February 9th-24th

Above: the “lava lake” as on February 24th, 2011

Located on the Hawaiian island of Maui, the Halema`uma`u crater is a pit crater located within the much larger summit caldera of Kīlauea. For the past couple of weeks, Scientists have been monitoring this area closely because of it’s activity. A lava lake has been developing in this particular crater. On February 9th, 2011, the lava surface had been quite shallow, about 90 meters below the floor of Halema`uma`u crater. On February 14th, ashy plumes were observed and by the 24th of February, the lava surface in the vent returned to about 80 meters.

This link will show you the ashy eruption on February 14th:

  1. Last time I checked Halema’uma’u is on the island of Hawaii the big Island.

    Hi Sarah!

    Second contribution here, I see.

    Personally, I would still like to see the date range all on the same line in the title – it really does look better. But I won’t mention it again.

    Source for your excellent picture? (Some idea of scale would help. You could be attracting readers from 1000s of km away and outside USA – spoon feed us just a little … Are we looking at a cauldron, a crater or a caldera?)

    I followed up both of your links:

    The short movie was great! A picture (especially a miving one – moving is even better) is worth 1000 words. My only comment would be that the url suggested it was January 2011 whereas you specifically identified it as February 14th. Assuming the url is correct, you could have said on the lines of – here is a similar eruption in January.

    The text piece looks to be from a news source rather than a technical source. While it seemed pretty good technically, if you could have found a technical source (USGS, Hawiaii volcano observatory) it would have given more weight and authority to support your piece. Not quite as bad as quoting Wiki, of course!

    BUT. All in all – a good piece of work. Beware the dreaded “it’s” See other comments …


    (P.S. Still liked your choice of movie!)

    (P.P.S Still appreciating the quality of all the pieces here – OUTSTANDING)

  3. Sarah, I hijack your post for a moment to comment on all the bloggers; it’s nothing personal, just some advice to y’all to improve your output.

    When you write on a blog, you never know how many people are going to read your post – and they all will form an opinion of you, based solely on your use of the (in this case) English language. I’m sorry to say that you do not pay enough attention to the basic use of the language: spelling and grammar. One day you are going to be scientists, I hope, and one of the most important tools of a scientist is the language. Go, learn your language so that you can use it better than I.

    (My English is a learned, foreign language – in highschool. My native Finnish is not an Indo-Europen language.)

  4. Sarah,

    you have a golden opportunity to report something remarkable: the new fissure eruption on Kilauea!
