On June 22, 1932, a 10- to 12-m-high tsunami wave struck ~60 km off the Mexican Pacific coast. The associated earthquake that apparently produced this tsunami is questionable because of its relatively small magnitude (M s = 6.9) to produce such tsunami heights. Historical documents, survivor testimony, tsunami catalogs, a post-tsunami survey report...

In volcanic environments, stratovolcanoes have great potential to produce landslides and debris flows due to their high relief. Their volcanic activity can trigger voluminous landslides along stream systems; however, these are rather infrequent. On the other hand, small but hazardous non-magmatic landslides occur frequently during volcanic repose....

The Trans-Mexican Volcanic Belt (TMVB) is characterized by a relatively low rate of seismicity. However, several damaging earthquakes have produced a loss of hundreds of human lives in the past centuries (e.g. 27/12/1568; 19/11/19123; 03/01/1920). The seismic risk in this region, in which maximum magnitudes of M 7 are expected, is increased by seve...
