What kind of volcano is Santa María?

Santa María is classified as a Stratovolcano in Guatemala. Its tectonic setting is Subduction zone / Continental crust (> 25 km).

How is seismicity near Santa María monitored here?

Earthquakes within 50 km of the crater are aggregated from 18 seismic networks and checked against a swarm rule that compares the current rate with this volcano's own 30-day background. Ash advisories come from the VAAC centres that are connected.

Volcano Santa María

Letusan Oktober 1902, salah satu dari tiga letusan terbesar abad ke-20, merobek lereng gunung dan menewaskan sedikitnya 5.000 orang di sekitar Quetzaltenango. Sejak 1922 kubah-kubah lava Santiaguito tumbuh di dalam bekas luka itu dan masih menyemburkan letusan abu kecil berkali-kali setiap hari.
