<p>Stromboli is one of the most active volcanoes on Earth with a continuous explosive activity and persistent degassing since at least 3-7 AD (Rossi et al., 2000). Being an open conduit volcano, its spectacular basaltic explosions interspersed by lava fountains occurring every ≈10 minutes (Ripepe 2002) make it probably world's best-know best-monitored volcano.</p><p>On 3<sup>rd </sup>July 2019 14:45:43 UTC paroxysmal explosion occurred ash column that rose almost 5 km above volcano. This very strong event was detected in several IMS infrasound stations, including IS42, located Azores islands middle North-Atlantic, distance about 3,700 km.</p><p>We present long-range detections allowed us to locate source based only estimated error less than 55 from ground truth event.</p><p><strong>Keywords:</strong> Stromboli paroxysm, infrasound, IMS, IS42</p>
