Masaya volcano (Nicaragua) - Smithsonian / USGS Weekly Volcanic Activity Report for 25 April-1 May 2001 (New Activity / Unrest)
mer., 25 avril 2001, 06:00 06:00 AM | AUTEUR : VNINETER personnel reported that volcanic activity at Masaya decreased following the 23 April explosion. Small explosions were observed on 24 and 25 April, but by 27 April only the continuous emission of gas at normal levels was observed with few episodes of strong degassing. Likewise, after the 23 April explosion the level of SO2 emission decreased and normal levels of seismic activity were recorded.
INETER warned that further explosions may occur that could affect areas near the crater (within ~500 m).
A tourist at the scene during the 23 April explosion stated that injuries were more serious than was reported either here or in news accounts. Over 100 tourists were near the crater when the explosion occurred, including infants and elderly persons. At least 15 people sustained injuries (bruises and cuts) and one person suffered a broken arm.

Masaya volcano (Nicaragua) - Smithsonian / USGS Weekly Volcanic Activity Report for 18 April-24 April 2001 (New Activity / Unrest)
At 1426 on 23 April a small explosion at Masaya's Santiago crater lasted for ~2 minutes and occurred in three phases. During the first phase volcanic gas under high pressure was explosively released and created a new vent in the bottom of Santiago crater. The eruption sent rock fragments up to 60 cm in diameter as far as 500 m from the crater. ... Read all
