Ans: Approximately 80% of the world's volcanoes are located beneath the oceans, on the seafloor. These underwater volcanoes, known as submarine volcanoes, form along tectonic boundaries, specifically at mid-ocean ridges where tectonic plates are moving apart.
Ans: Yes, during an eruption it is possible to see lava in Iceland. Volcanic eruptions and the associated lava flows can be an awe-inspiring sight. However, it is critical to prioritize safety during such events. Authorities and guided tours ensure visitors can witness these phenomena from a safe distance. It's also important to note that volcanic activity is unpredictable, and the opportunity to see lava depends on the timing of your visit and the current volcanic activity. Always refer to the latest updates from official Icelandic sources.
Ans: While Katla is one of Iceland's most powerful volcanoes and has one of the largest volcanic calderas, it's not the biggest in terms of overall size. That title goes to Bárðarbunga, which is part of the Vatnajökull Volcano system. Bárðarbunga's caldera alone spans approximately 70 square kilometers, and the whole system is considerably larger. However, when assessing the volcanic size, various factors can be considered, including the volume, height, and caldera diameter, each of which might yield a different 'biggest' volcano.
Ans: If Katla, one of Iceland's largest and most active volcanoes, erupted, it could have substantial local and global impacts. Locally, an eruption could cause massive flooding due to the rapid melting of the overlying Mýrdalsjökull glacier, a phenomenon known as a jökulhlaup. Lava flows, and ash fall could also endanger nearby communities. Globally, the eruption could impact air travel, similar to the Eyjafjallajökull eruption in 2010, which disrupted air travel across Europe for several days due to the ash cloud. It's worth noting that the specific effects of an eruption would depend on many variables, including the magnitude of the eruption, the prevailing wind conditions, and the measures taken to prepare and respond.
