I did point that the lahars killed 23,001 people in Colombia not so long ago. That's outside of the US.

If anyone else knows of towns outside the US that have lahar warning systems, please add them to the article. -- hike395

Added Mount Ruapehu. -- hike395


Lahar comes from the indonesian word Berlahar, it was cut short because Kapampangan Filipinos who were blasted by Mount Pinatubo could cut the word short, it was soon accepted as a world-wide term after Dr. Reynaldo Punongbayan of PHIVOLCS gave it recognition decades before.

isn't lahar an icelandic word?

edit

Isn't lahar an icelandic word? It's my understading that a lahar can only occur when a volcano melts snow or a glacier (neither of which Indonesia has much of!). Otherwise, it's just a plain old mudslide. --radiojon 09:08, 2003 Sep 6 (UTC)

The USGS says that it is an Indonesian word: [1]. It doesn't need snow or ice: a lake of water can cause lahars. They have them in Indonesia, see [2], which states:
  • As the 1982-1983 eruption waned a crater lake began to form. The presence of the lake, high rainfall, and the large volume of exposed pyroclastic material on the volcano have made the hazard associated with secondary lahars very high.
Dunno, but I used to call everything solid out from crater lahar at my childhood, wether it was lahar or lava, we called it lahar in informal Indonesian.Aditthegrat 15:55, 15 May 2006 (UTC)Reply


It's not, it comes from the Indonesian word Berlahar cut short.- FromTarlac — Preceding unsigned comment added by FromTarlac (talkcontribs) 00:18, 27 December 2010 (UTC)Reply

Incorrect picture

edit

The picture of MT. St. Helens doesn't show a lahar, but instead shows a pyroclastic flow. Lahar forms from icemelt and ash mixing, would be a mid-range gray, and would not originate from the middle of the volcano, as shown by this map: Mt. St. Helens aftermath Would it be possible for someone to get a better picture of a lahar? 71.36.204.207 (talk) 05:45, 6 February 2009 (UTC)Reply

Lahar is Indonesian/Javanese.

edit

It comes from the word Berlahar... — Preceding unsigned comment added by FromTarlac (talkcontribs) 00:01, 27 December 2010 (UTC)Reply

Javanese seems more likely, Java island is full of active volcanoes. Malay origin is doubtful, considering that virtually all Malay ethnic live in coastal areas in Sumatra, Borneo and Malay Peninsula, where there are no volcanoes. — Preceding unsigned comment added by 203.82.93.24 (talk) 09:42, 10 November 2012 (UTC)Reply

Decimate

edit

The lead says "...even been known to decimate entire settlements." Decimate (properly speaking) just means "reduce by 10%". I believe the editor intended something stronger. I know "decimate" is used colloquially to mean great destruction, but in an encyclopedia we should be more formal. The sentence does not have a cite, but the body describes destruction of an entire community. Would "destroy" or "devastate" be too strong? --D Anthony Patriarche (talk) 05:54, 30 May 2019 (UTC)Reply
